10 Reasons Why Hosted Desktop Services Are A Good Idea And What It’s All About


Hosted Desktop

There’s quite a buzz about Hosted Desktop Services (HDS) these days and for many businesses it makes a lot of sense. Maybe it doesn’t initially look so great for some IT support companies and departments but if embraced in the right way it can be a benefit for them as well.

HDS, sometimes referred to as cloud services or software as a service, is not really such a nThin Clientew idea. Before people started using PC’s as the mainstay device most computer systems had servers and intelligent workstations which we now call thin clients. Unix users will be very familiar with this concept.

Intelligent workstations like the thin clients of today had some memory and processor capacity but they mostly accessed software off of a server. Now that good broadband supplies are available the same type of system can be accessed over the internet. It has always been a good system!

In a nut shell a Hosted Desktop Service is “your PC” managed remotely and that can be accessed anytime, anywhere, from any device without all the headaches of maintaining it or the loss of performance that you often get with Windows based PC’s.

Here are 10 reasons why it’s a good idea for many businesses!

1 – A Uniform Experience Everywhere On Everything

Putting software on a central server means everyone can access the same software from anywhere. No more worries about which versions, which licenses, upgrading versions etc. Many HDS services will give access to software using apps that will work on nearly any device such as Citrix which works on Windows, Android, Apple OS, Linux, Unix, phones, tablets and other popular platforms that I may have missed out. It will work on different versions of different operating systems too!

2 – Backups & Security All Looked After For You

Backup and security are a necessary pain. It can be a worry when considering HDS, after all, how good is the suppliers backup and security? The answer is that it has to be good! Some companies will undoubtedly be storing sensitive and valuable data so HDS suppliers need to make sure everything is backed up in real time or close to it, often across different server locations in different countries.

Security has to be really good because if anyone hacked into the HDS systems it would be trouble for customer and supplier alike. That goes for up-time too which needs to be 99.99% of the time!

Because the software and data is stored on the HDS servers if a device is stolen or lost it’s no problem especially with HDS sessions timing out.

Similarly antivirus and anti-malware services are all taken care of.

Backup, security and availability will be better than that which most companies have on their own systems.

3 – Speed

If you have used Windows based machines you will be familiar with the way that they can slow down over time. Maybe because there is too much software on a PC, because of a virus, perhaps the hard disc has faults, not enough memory or maybe the computer is just generally underpowered. This is not a problem with HDS where the servers are high quality, fast and maintained for you. The servers are doing all the work for you, all your device has to do is run the software that allows you to access the servers which doesn’t tax a device or use much internet bandwidth.

It’s like having a new PC everyday. People can work faster, be more productive and won’t have the frustration associated with slow computers.

Just as an example I tested loading up Microsoft Word and a few other Microsoft products and the load up times were between half a second and 2 seconds.

4 – Proactive Support

Another headache with maintaining software and hardware is keeping everything up to date, often across many devices. Most of that won’t apply with HDS as support staff are keeping everything up to date for their customers and monitoring systems for faults.

HDS users will still have queries and sometimes things may go wrong so it’s important that support is available during working hours and maybe even 24/7support. This is a level of support available with HDS as many companies are using it and some at all hours.

5 – Improved Cash Flow

HDS is a scalable subscription service where different people can use different software at different times. This gives flexibility that can be controlled. The cost can be fixed to be the same each month or it can be capped to how much a customer is willing to spend each month allowing flexibility without loss of control. There are few unexpected expenses to accommodate. HDS is an easy service to build into a company’s monthly and yearly budget.

6 – Mobility

Because it works anywhere in the world where there is an internet connection and on almost any device it can be used in London, Sydney, Delhi or perhaps even in space (one day). No special connections are needed. If a company moves office it doesn’t matter, if someone has to work at home it doesn’t matter. Use a PC, tablet, laptop or even a phone!

Intel NUC Thin ClientPeople can use their own hardware or simple thin clients* with any suitable screen.

*A thin client is a small box used to connect everything together such as a screen, a keyboard and a mouse. It can be simply configured to access an HDS service. Thin clients often have a built in card reader, sockets for USB devices, headphones etc. They rarely have any discs in them and don’t need heavy duty processing power. Typically they are around 8 inches square and 2 inches deep. They use much less power than a PC too so cost less to run.

7 – Less Hardware And Software Worries

A company running its own system might have a list of IT concerns that go something like this:

  • Hardware to maintain and replace
  • Software to maintain, upgrade, fix, replace
  • Provisioning of new hardware and software
  • Security
  • Backups
  • Software version control
  • Licensing
  • Operating system support; possibly across different versions or even different OS types.
  • System availability
  • IT support, in house or contracted out
  • And more …..

At the time of writing Windows XP has recently been phased out of Microsoft’s support regime but lots of companies still have it and have the headache of what to do next as they can’t stay with XP forever. This is not an issue with hosted desktop services as it’s all kept up to date on an ongoing basis.

Most of the hardware and software that had to be looked after before is no longer a concern with HDS.

With HDS there is often a core set of software that everyone gets such as Microsoft office, Chrome, Adobe Reader etc. Other optional paid for or free standard software can be chosen from. Other off the shelf or bespoke software can be requested and put onto the system for selection or as part of a customer’s standard HDS setup.

The purchase and use of software by people or groups of people can be controlled by an approval system so that a company has control over what they are paying for.

The data for software used can be retained even if not used or paid for all of the time.

With HDS people can’t just download software as they like. Miscellaneous software can come with viruses or malware or compromise the working environment. This is another built in method of controlling the integrity of company IT systems.

8 – More Time For Your Business

Depending on how much IT infrastructure a company has and how it uses it, a significant amount of time might be spent planning and implementing IT strategies. In turn a company may have to spend time communicating with their IT support department or provider. Some of this time will be concerned with day to day IT matters such as security, backup, housekeeping etc. If much of this is offloaded onto HDS either the IT support function can be reduced or diverted to other important company IT projects.

Using Hosted Desktop Services can result in more time spent on a company’s core business and less on IT leading to savings and increased productivity.

9 – Integrate With Your Own Special Systems

A company might have some software and data that they want moved to the HDS servers and for most software this can be done. It’s sometimes referred to as on-boarding. There may be one-time costs for this but once it’s done that company won’t have to worry about looking after it again.

A company might have some systems that just aren’t suitable for HDS for example; a film company might have editing suites with specialized hardware and software that maybe 25% of the company use. Systems like these can be kept as they are and HDS still used in conjunction with those systems where required. Where needed data can be shared, synchronised and local data can be accessed directly from HDS!

10 – A Low Carbon FootprintLow carbon footprint

Last and not least you and your company will be doing your bit for the environment. The servers used with HDS are usually high quality enterprise servers that use less energy than others and a reduced carbon footprint all round.

If you and your company are using thin clients you will be using less energy at the office end which reduces your own carbon footprint and means you will make some savings too.

Each user takes 100k to 200k of internet bandwidth per session which could be less than what is used normally. Less internet capacity may be needed and may be reduced or utilised elsewhere.

A Special Microsoft Office 365 Note

Microsoft Office 365 is not a hosted desktop service, you still need a company hardware infrastructure. HDS gives you the benefits of Microsoft Office with far more flexibility and without all the maintenance.

Is Your’ Internet Connection or Wireless Letting You Down?


No internet connection

My business relies on the internet; my phone is an IP phone, it uses the internet. If the internet goes down so does most of my business until it comes back up in maybe hours or days. It doesn’t stop there though because even my TV uses the internet these days and then there’s all those cloud services which means some of my data may not be on any of my computers. I’m running a cable internet connection and it’s pretty fast especially when it comes to downloads. The faster the broadband the more we can do with it and the more we rely on it. And … it doesn’t even stop there either! Laptops, mobile phones, tablets, TV’s, set top boxes, NAS drives, stereo systems, cameras etc. use wireless so wireless is really important too.

If you are running an internet reliant business or would really miss your internet connection at home you won’t want it to go down ever! Well, maybe when you are on holiday … uh oh, got a remote security camera linked to your phone through the internet or some other device, maybe a remote internet linked pet feeder or something.

I think most of us want reliable all the 9’s uptime for our internet but of course that’s not always easy to achieve. Making it 100% reliable I cannot promise in fact even all the 9’s is not that easy but I can probably show you how to make your internet faster, have a higher capacity, make it more reliable and improve your wireless WITHOUT SPENDING A SMALL FORTUNE!

A Common Problem

Most homes and small businesses have one internet connection, one line and one router that functions as a router a switch and a wireless access point … true? If any of those elements go down then so might your internet access. You could go ask the neighbour if you could sling a wire through to your business from their supply or ask for their wireless password and maybe sometimes this is ok, it’s a temporary solution of a sort. If you want to be self reliant though you’ll need another solution.

What happens if …

Your router fails

Simple, go get another router, configure it up (hope you know where your broadband login details are) or better still, have another router on standby, just in case! From my experience most people or businesses don’t have a spare. Your current router might be a bit special but anything will do to get you back up and running if a direct replacement is not to hand.

Your internet connection fails

Could be your ISP, a fault on the line or a JCB digging outside. Either way it’s down to the service level agreements of your provider. You’ll probably be down for a few hours, maybe a few days and if you are really unlucky, a few weeks, it happens, especially if the road needs digging up.

Flaky Wireless

Wireless has come a long way but it’s still a flaky service. It depends on lots of things, how many people are already connected, what’s in your building, atmospheric conditions, the type of wireless network you have and the capabilities of the devices you are trying to connect to it etc.

It’s also not so great when you have more than one wireless access point but your device stays connected to the access point you were near 2 minutes ago and which is now nearly out of range. You could be standing next to another access point on the same network but still not connect to it unless you manually do so.

Does all or some of this sound familiar?

A Solution

JCB cuts cables

There are very fast internet connections with high up-times and excellent service level agreements that mean if your internet connection does go down it gets fixed quickly but of course that can cost a lot of money and a JCB going through the cable is probably going to scupper even that plan for a while. There’s WiMax, line of site links and even satellite connections but, well, it’s a bit expensive and maybe a bit over the top for many.

My suggested solution below is not new but it has improved over time and costs less than it used to. I’m a fan and distributor of Draytek network devices so I’m going to use and suggest Draytek in my solution but you can use other brands solutions too it’s just that I know Draytek works well, is generally of a good quality, has a high specification etc. Lot’s of businesses and computer support companies use them so I guess that’s an endorsement in itself.

More than one

Broadband is pretty cheap so how about 2 supplies over different networks so that if it’s the ISP or just one line that fails then the other is likely to continue to work. Just to make it belt and braces how about feeding in a mobile broadband supply just in case that clumsy JCB comes our way and cuts all the cables to your premises (don’t laugh, this happened to one company I worked for).

In this case you would have 2 broadband feeds going into the same router which would balance all your internet traffic using the 2 services giving you more speed and capacity. If one broadband service fails then the other carries on until the failed service comes back up. If both services fail then the mobile broadband cuts in.

Draytek vigor 2860 load balancing

The mobile broadband does depend on the mobile signal you can get where your router is located and whether it’s 3G or 4G but at least it will let you access the internet. If it’s 4G this could be pretty good! You will need to watch your mobile broadband use depending on the tariff you are using but at least you are still up and running.

What if the router fails? Well of course this can happen so for the cost of it I would keep a second router as a backup. You can backup the configuration of the router in use and load it onto the second router. You can backup the configuration each time you change it and either load it onto the second router or at least have it ready. With some Draytek devices, this one included there is 3 year extended warranty available where they will replace your failed device the next working day with no quibbling. You could even use the second router as a second modem if you configure it correctly but that’s a subject for another day.

Improving Wireless Connectivity

Wireless or WiFi has improved over time. The range is greater, it’s more reliable and easier to connect up to than it used to be but it’s still a variable and sometimes quirky technology. If you need a consistent service over a defined area then you’ll probably need to over do it with wireless coverage.

Many routers are not just routers, they are routers, switches, modems and wireless access points. The wireless part of your main router will provide all you need in a small space but as an operating space gets bigger you will need further wireless access points to cover the area. Wireless access points can be obtained for both indoor and outdoor environments and can work well in a campus type environment.

Two Variants

There are two main variants which we can call push and pull systems. To use a couple of techy terms, the wireless system is called the server and your mobile phone, laptop tablet or other wireless device the client.

Pull

Most domestic or small office wireless systems are pull systems which means you manually connect your client device to a wireless server. For example, an office or house has 2 access points, one is a wireless router downstairs and the other is a wireless access point upstairs. When your client device is connected to the downstairs router (a server) it stays connected to it until it goes out of range so if you walk upstairs you may need to manually disconnect from the downstairs router and connect to the upstairs wireless access point. It works but it’s clunky and moving smoothly from one wireless zone to another does not occur. Both wireless access points are part of the same system but the connection to them isn’t managed automatically. You could say that you have to pull connections.

Push

Using the same scenario now the wireless system is being managed and pushing Managed Wirelessconnections. The effect is that when you walk up the stairs the wireless management software built into the system monitors it’s connections and as the signal from one wireless access point becomes weaker and another stronger it pushes connection to the stronger wireless access point to your client device such as your phone.

Another great thing about managed wireless is that it will share the load so if several devices are in range of more than one access point those access points can be made to share the wireless traffic instead of one being overloaded and the other hardly used.

Now you can walk up and down stairs with your client device and stay connected without having to think about it. Where two or more access points are located to manage a lot of wireless traffic they can look after the traffic loads so the user gets a good solid wireless service throughout the operating area.

Sounds Expensive

Managed wireless used to be expensive but it’s not now. It does cost more than pull wireless but not much more and is well within credible cost for domestic or small business users. If you need it it’s well worth the modest extra cost.

If you wanted to set up managed wireless using Draytek components you would need either a Draytek Vigor 2860 or a 2925 series router to act as the controller and either a Draytek Vigor AP810 or AP900 wireless access point.

Here is my suggestion for a robust broadband set-up with managed wireless for around £525+VAT for the equipment. All the prices are relevant at the time writing so whilst prices and devices may have changed by the time you read this I am sure this kind of system will be around for a good while yet!

You will also need 2 broadband supplies which can be a mixture of ADSL max, ADSL2+, Fibre known as FTTC or some other suitable broadband/Ethernet supply. You can use Virgin cable broadband. 2 lines carrying BT like broadband will give you 2 lines of voice as well. The cost of installation of the lines and broadband might come to somewhere between £200 and £250 + VAT. Monthly rental for the 2 lines and broadband might be around £60 to £90 + VAT depending on what you have.

From new:

  • All equipment and line installations maybe ~£775 + VAT
  • Ongoing monthly rental, maybe ~£75 + VAT
Draytek Vigor 2860n Draytek Vigor 2860n ADSL Router £180.32 + VAT The most popular business class router from Draytek. It acts as a controller for the managed wireless as well as managing dual broadband connection with a third mobile broadband connection.You could get 2 of these, 1 to use and 1 as backup.
Draytek Vigor AP-900 Draytek Vigor AP900 Wireless Access Point £113.85 + VAT Currently the top of the range wireless access point from Draytek. Lots of speed, power and flexibility.If the wireless range from your w860n router is not enough then get at least one of these.
 Draytek Vigor 120 Draytek Vigor 120 Modem £41.80 + VAT You may or not need one of these depending on the broadband you have. This can used to feed a second broadband supply to the 2860n router such as ADSL2+. It cannot be used with fibre broadband. Alternatively you could use the backup 2860n as a second feed if configured correctly but you will lose the second feed if the main 2860n goes down and you have to use the backup instead.
 Draytek ADSL Tailed Microfilter Draytek ADSL Tailed Microfilter £5 + VAT These split your voice and broadband elements into 2 so you can access broadband and make phone calls at the same time.You could get 2 of these, 1 to use and one as backup.
 Optional items
 Draytek Vigor AP810 Draytek Vigor AP810 Wireless Access Point £82.80 + VAT You can use these instead of AP900’s. It’s not quite as fully featured as the AP900 but if you don’t need those features it will work perfectly well with managed wireless.
 Draytek VigorCare Extended Warranty Draytek VigorCare Enhanced Warranty Subscription B £36.40 + VAT For Draytek Vigor 2860 series routers. These extended warranties are worth having. They don’t cost much and they will get you a new device the next day. See below for more information*
 Draytek VigorCare Extended Warranty Draytek VigorCare Enhanced Warranty Subscription A £24.70 + VAT For Draytek Vigor 120 modem’s and AP900 or AP810 wireless access points. These extended warranties are worth having. They don’t cost much and they will get you a new device the next day. See below for more information*

*Draytek VigoreCare Extended Warranty Main Features

  • One per device.
  • Upgrade of warranty to 3-years
  • Advanced-Replacement of faulty unit the next working day subject to delivery destination
  • Cover for the whole 3-years for one payment

100 Snippets

Over the last few months from the 5th September 2012 until the 5th April 2013 I tweeted 100 snippet’s of information about networking, routers, broadband etc. I also published them as updates in LinkedIn and most in eCademy/Sunzu.  I hope some people found them useful. I have preserved them here in case anyone  would like to dip into them.

The objective was to explain bits of tech in small digestible chunks that were hopefully fairly easy to understand.

What can I do with my router – part 2?


Draytek Vigor 2860n
More about basic router set-up information …

Default DNS, primary, secondary

DNS stands for “Domain Name System”.   This is important for browsing the internet.  Each web site you go to resolves to a 4 part IP address such as 212.58.244.70 (in this case www.bbc.co.uk).  Try it, type 212.58.244.70 in your browsers address bar and the BBC website will come up.  Clearly it is a lot easier for us humans to remember www.bbc.co.uk instead of a 4 digit number separated by decimal points.  There are many DNS computer servers around the world that translate website names into their respective IP addresses so that you can easily access them.  Normally your Internet Service Provider automatically provides 2 x DNS server IP addresses when you connect to their service.  Primary and secondary DNS server IP addresses are provided so there are 2 x DNS servicers to go to.

DNS server addresses

You don’t have to use your ISP’s DNS servers but they are usually the most convenient as they are automatically supplied.  The most likely situation when you might want to change these is if your ISP’s DNS servers have a problem, in this case you could temporarily use public DNS servers.  You can easily find some on the internet by Google’ing “public DNS servers”.  Take a note of some so that you have alternatives in hand should your normal DNS servers have a problem or your router does not pick them up when connecting to your’ broadband.  In fact, Google have public DNS servers, see https://developers.google.com/speed/public-dns/.

IPV4 and IPV6

If your eyes start to glaze over in this bit then skip to the next bit but actually this is quite important going forward.

An IP address is used by devices such as computers, mobile phones, routers, web sites, internet phones etc.  It’s the same as each house, shop, town or railway station, everywhere has an address.  An IP address is a 4 part number like 212.58.244.70 which is given to each location on the internet so that it can be found.  A 4 part IP address is an IPV4 address.  When IPV4 was implemented people did not imagine how many devices, websites etc there would be and the result is that IPV4 will not be able to provide enough unique addresses needed for all that it will be used for.  This means we need to move to a standard that will allow for more addresses and that standard is IPV6.

IPV6 is an 8 part address in hexadecimal notation separated by colons such as “fe80:0000:0000:0000:0202:b3ff:fe1e:8329”.  Not so easy to remember or read but it will allow for many more IP addresses.  An IPV6 address also carries more routing information and an 8 part IP address can carry more information than a 4 part address allowing for more efficient data routing and better allocation of IP addresses to countries, for different uses etc.  If you want to know more please see IPV4 and IPV6.

Subnet mask

Hmmm, well, this is a tad more techy.  In effect a subnet mask is used to identify the boundaries of a network or if you like the number of IP addresses available to it.  To keep it simple your router will have an address starting with 192.168 and then it will probably have 0.1 or 1.1 as the last part so for example you get 192.168.1.1. Well, so what?!  This is the local address of your router; 192.168.1.1 it is the first address of your own local network.  It’s like the first address of a flat in a block of flats.  The subnet mask lets the router know how many flats there are in the block.  Say your router has a local address of 192.168.1.1 and each device such as a computer or mobile phone that connects to it must have a unique local IP address, for example:

  • 192.168.1.1         My router
  • 192.168.1.2         My desktop computer
  • 192.168.1.3         My laptop
  • 192.168.1.4         My mobile phone
  • 192.168.1.5         My internet phone

If your subnet mask is 255.255.255.0 then the pool of local IP addresses will be 192.168.1.1 to 192.168.1.254 allowing for 254 devices to be connected to it.

A subnet mask can be used at local level, company level, country level etc.  IP addresses are shown as decimal numbers for our convenience but the network sees them as binary numbers and masking is a technique used to evaluate binary numbers in certain ways.

A technical explanation of how binary works and network topography is beyond the intention of this blog so I will move on.  If you are curious then have a look at InetDaemons article.

Subnet Mask

MAC

In this case we are not talking about the Apple MAC computer or an item of clothing meant to keep the rain off (sorry, I am known for my very bad and not very funny jokes).  A MAC is a Media Access Control address and it looks like “01:23:45:67:89:ab”.  Every device that can be attached to any part of a network has a unique MAC.  For example a mobile phone that can be connected to a network will have its own unique and permanent MAC.  This is different to an IP address.  An IP address will be given to a device when it connects to a network and may get different IP addresses from different networks but its MAC will always be the same.  You might enter different buildings and stay in different rooms but you will always be you, a unique individual!  In the same way any device connected to the internet could be identified wherever it is in the world if its MAC is known.

Dynamic  / Static IP addresses

Ahh, something simpler to explain.  When your router connects to your ISP it will be given an IP address.  Each time you connect you might get a different IP address, this is known as a dynamic IP address.   If you want to connect to your London office from your office in Birmingham then it’s not going to help if the IP address of the London office keeps changing!  In this case your ISP can give you the same known IP address each time your router connects to that ISP, this is known as a fixed or Static IP address.  Change your ISP and your static IP address will change

DHCP

Dynamic Host Configuration Protocol!  This is the system that hands out IP addresses to devices that attach to your network.  This is often performed by routers but on larger installations it is usually performed by a computer server.  Only one system should be handing out IP addresses on a network, all other DHCP capable devices must have this feature switched off otherwise there will be chaos and your network will not function properly.

LAN

This means Local Area Network.  This is a network usually confined to one location although that location could be large such as a site with several buildings.  It excludes networking over the internet although a LAN can access the internet.

For example, in your home or small office, a desktop computer, a networked hard disk, a mobile phone, a tablet might all be connected to the same router either by wires or wirelessly.

This could  be your home LAN:

Home or small office LAN

An office LAN might have many computers, switches, servers etc. connected.  It might have LAN’s within LAN’s, it might be complicated with lots of security but it is still a LAN.

WAN

This means Wide Area Network and is the network that links different locations together.  They might be locations that are in the same city or country or it could be linking locations in different countries.  The links might be private links setup by companies to link their locations together or links might be over the public internet.  The World Wide Web (www) works over a very large WAN.  If you work for a large company you might have an intranet which is like the World Wide Web but is maintained by your company, is private to your company and perhaps its customers, this will work over a WAN.

Packets

I like packets, especially ones with nice stuff in them that come through the post.  Metaphorically that’s more or less what we are going to look at now.  When you order something to be delivered to you, you often receive a box with an address attached to the outside.  The address label might also have a return address on it and perhaps some information about what’s in the box such as the contents, weight, size etc.  Inside the box there may be another box with more information on it and maybe even another inside that, eventually you will get to the actual contents.  Sometimes you might receive a box with just simple information and the actual contents present themselves as soon as you open it.

Simple Data Packet

Data packets are like a mail order box.  A packet is a chunk of data with a header that tells the network about what’s in the packet, where it needs to go and what method should be used to move it around.  Sometimes there will be a footer which is used to mark the end of the packet and may have a special number in it to verify that the packet is complete.  Like the box analogy there may be packets within packets.

If you think I have missed something out that is basic let me know and I will add it as appropriate to a third article although I guess it is a matter of opinion where to draw the line.

I’m going to start another category; “I want to <something>” and the next article will be “I want to setup a wireless LAN” as this is one of those questions that come up often.   This will include Wireless LAN basics.

Well, I think that’s enough for now, how am I doing?

 


What can I do with my router part 1?


Draytek Vigor 2860n Front

It’s been a while since I wrote an article for this blog.  I’ll skip the excuses and see if I can muster some continuity from now on

I thought I’d touch on some basic set-up information and maybe some more useful feature setup info.  Routers vary so I might talk about some things your router doesn’t have or maybe uses different terminology.  Your router may have some features I don’t mention.

Basic internet connection

Most routers have set-up wizards or make it easy for you to get connected to the internet even if you don’t know what it all means and if that’s as far as you want to go then fine but if you are a bit more curious then read on dear reader.

PPPOA / PPPOE

Let’s get straight into the acronyms!

This will be one of the first configuration choices when you want to connect to the internet manually.  In this country PPPOA is the common choice and may be the default, it stands for “Point to Point Protocol over ATM”.  PPPOE is over Ethernet instead of ATM.  In English it is simply the way that your router is going to connect to your provider so you can access the internet.  It handles your login details and holds up your’ connection.  ATM stands for “Asynchronous Transfer Mode” (and I’ll thank you to stop yawning) which is the way information is switched or if you like traverses the “internet / network”.  PPPOA uses your login user name and password to authenticate your connection.

PAP & CHAP

PAP – “Password Authentication Protocol”, CHAP – “Challenge Handshake Authentication Protocol”.  These are two methods of handling the authentication process.  CHAP is the more secure.  Your router may be able to work this out for itself and you may be able to choose “PAP or CHAP” as a setting.

VPI / VCI

Usually have the value of 0 and 38 respectively.  VPI is for “Virtual Path Identifier” and VCI is for “Virtual Channel Identifier”.  Different countries have different combinations of values, 0/38 is the UK combination and this identifies the next destination point for your data to go to, initially the BT network.

Encapsulation

VC-MUX stands for “Virtual Circuit Multiplexing“.  This is a method of controlling how little bits of data (called packets) get around.  LLC or “Logical Link Control” and SNAP or “Sub-network Access Protocol” are other methods that may be used.  VC-MUX is common in the UK.  I’ll leave it there otherwise we will have to enter techy hell analogous to taking a clockwork watch apart and trying to put it back together again.

Modulation

Er, um, this is old school stuff.  This is the way a frequency is used to transmit and receive information.  There are several ways of doing this for example if a frequency is changed between 1000hz and 1001hz then 1000hz can be used to signify a “0” and 1001hz can be used to signify a “1” and so, an analogue signal can be used digitally.  Changing the strength (amplitude) of the signal or staggering it (phase) are other ways.  Anyway, different types of broadband use different regimes so you can either choose the appropriate modulation by broadband type such as “ADSL2+”, “ADSL2+ Annex M” or set it to “Multimode” so that the router can work it out for itself.  There are times when the router may have trouble doing this in which case you may need to pick the correct setting manually.

Frequency Modulation

Always on / Nailed Up and Idle Timeout

If given the option and you want your broadband to remain connected continuously then tick “always on” (this is sometimes referred to as “Nailed Up”).  If you don’t want the connection to disconnect if it’s not used for a while then set the “Idle Timeout” to -1.

Ok, that’s enough for now.  It’s not riveting stuff unless you are techy minded in which case you probably already know all this.  Let’s look at something a little more interesting …

Load balancing and failover

Oh dear, my ISP (Internet Service Provider) is having some problems today and my internet has gone down, what am I going to do or … our business is growing and our broadband is not fast enough anymore but I can’t afford one of those expensive leased lines just yet, what shall I do, boo hoo

Well folks, there is an answer … “Load Balancing” and “Failover”.  Certain routers can accommodate this such as the Draytek Vigor 2830 or 2850 series or the Billion BiPAC 6200 NXL.  These routers can take a second broadband supply and balance the 2 supplies to give you more capacity.  If one supply fails the other will continue to work.  You will need an inexpensive broadband modem such as the Draytek Vigor 120 for the second connection and you will probably want the broadband supplied by two different suppliers who use two different networks as if one ISP has problems hopefully the second will keep on working.

Dual WAN setupMobile broadband failover

Ok, so what happens if a digger working in the street cuts all my telecommunication cables?  Well, you can also plug a mobile broadband modem into a USB port in the router for failover only.  This will only work if the signal is strong enough in your area / premises and it probably won’t be as fast your land line broadband but at least you can continue to function.

Ok, so what happens if the router fails?  Have a second router configured as a standby.  If broadband is critical to your business then this is a very small price to pay for some assurance.  You might want to protect your routers electricity supply by plugging it into a UPS (uninterruptable Power Supply).

Well, I think that’s enough for now, how am I doing?

Next time I’ll talk about some more basics and, now, let me see, hmmm, maybe wireless, Firewalls or VPN’s, not sure yet.


How can I get more from what I already have (broadband)?


Is your broadband performing as well as it could be?  Maybe it is frustratingly slow or you are thinking, maybe I could get more out of it?!  There are quite a few factors involved in how good a service you get so I am going to go through them using a check list with explanations approach.  It may not be exhaustive but I hope it will help.

My equipment

If you think you have a problem with your broadband and you call your ISP the first thing they will ask you to do is check your equipment so let’s do this first.

  • Old BT sockets and iPlates.

    iPlate

    • Some older BT sockets have bell ringer wires that interfere with broadband.  You can isolate this by plugging an “iPlate” into your BT master socket if one is not already fitted.  Bell ringer wires are not needed for modern phones.  This can make a significant improvement where relevant.  It is possible that more recent ones have bell wires as well.
  • ADSL filter – This is the little box that splits the voice element from the broadband.  You plug your phone into one socket and your router into the other.  You will find it plugged into a phone line wall socket.
    • If an ADSL filter is not being used then start using one, the difference can be quite significant.

      Tailed ADSL Filter

    • Are there secondary extensions taken from the back of the master socket?  If there are each one that you are using must have an ADSL filter even if it’s just a phone or a fax machine plugged into it.
    • Is your ADSL filter faulty?  All you can do is try another one and see if it makes a difference.
  • Cables– The network cables that you use between the BT socket and the router or from the router onwards are important.
    • Are any cables damaged?
    • Are there any suspect plugs or sockets?
    • If any are suspect try replacing them with another cable and see if that makes any difference.  You may be able to swap them around to check.  One faulty cable coming from the router to a switch for example could compromise the whole network.
    • Are they too long?  The maximum recommended distance for a cable run is approximately 100 metres, after that things start to deteriorate.   Either use shorter runs or boost the signal by adding a powered switch along the way.
  • Routers and switches.
    • Is your router able to handle the service plugged into it, for example older routers may not be capable of handling ADSL2+ in full or in part.
    • Can the router handle what you are putting through it?  If you have 50 users going through a cheap router then it may be too much for it and therefore you may perceive your broadband to be slow or unreliable.  Try a better router.
    • Is it a 10/100 router or a gigabyte router.  Older routers may only supply 10mbs to your local area network (LAN) which is probably not enough these days.  Make sure it is at least supplying 100mbs or better, gigabyte speeds.  This partly depends on your connected devices such as an old PC with a network card that will only support 10mbs.  As above if you suspect your router try another more recent one and see if this makes a difference.
  • Devices.
    • Is your laptop PC, desktop, tablet or smart phone slow?  If other devices are getting good speeds then it’s probably not the LAN or your broadband etc, it’s just that particular device or the network card in it.
  • Web sites.
    • Some websites are faster than others so check by using a control website such as www.bbc.co.uk or another reliable site.  If this appears slow then it’s not slow websites that are the problem.  You can use www.speedtest.net to check your speed when no-one/nothing else is using your broadband.

My location

The distance between you and your BT exchange and the quality of the cables etc. between can make a big difference.  If you are next to the exchange then your broadband service should be very good but if you are 10 kilometres away, the BT cable is old and not so great then the service you get may not be so good.  Too far away and / or poor cables could at worst mean you don’t get a useable service at all or it may be unreliable. See my previous blog for more information about this.

There is not a lot you can do about this unless BT are prepared to replace some of their infrastructure but this is probably unlikely.  Sometimes just having a new line put in will give you a better (or even worse) broadband service as this line may take a route back to the exchange using different cabling.  BT has been known to replace the bit of cable between the green box on the street and premises but there are no guarantees that they will do this or that it will make a difference.

What can your ISP do for you?

Time to get a bit more technical but I will try and make this easy to understand.  This bit you can’t really control but to some extent your ISP (Internet Service Provider) can.  Some characteristics of your broadband depend on your ISP and the networks they use.

  • Sync – This is simply the raw up and down connection speeds that your router reports on its online status page.  It is the speed of connection between your router and your ISP.  If you check your speed with something like www.speedtest.net it won’t be quite as good as this is the speed you get accessing the internet which is beyond your ISP’s area of control

    Draytek router sync status

  • SNR or Signal to Noise Ratio – Pick a phone up and if the line is noisy (not the phone itself) then you are not likely to get as good a broadband service as when it is quiet.  Broadband might be a digital service but a normal phone line is an analogue transport service and noise on it will interfere with a digital service which is not so tolerant with interference and causes data errors.  BT fixing faults, should there be any, in their infrastructure could improve this.

You can usually see the SNR on your routers online status page.  It’s measured in decibels and a good average is 6db.  If the line is noisy and the signal is not strong enough there will be lots of errors which means the broadband appears slow as data with errors has to be re-sent to you.  Your ISP can change the SNR in 3db stages from 3db to 15db to increase the signal strength.  Increasing the SNR will slow your broadband down but if there are fewer errors then from your point of view it goes faster.  Get your ISP to increase the SNR by 3db at a time and try it out for a few days each time.  If it gets better, keep going until it slows down again or you get to 15db.  If you get to say 9db and works better then go to 12db, if it slows down then get your ISP to back it up to 9db again.  It’s a balance between speed and errors.

  • Attenuation – This is measured in decibels.  It’s the quality of signal.  10db is good, 30db is ok, 60db is acceptable, just about, more than 60db and things rapidly go downhill.  Apart from changing cables or moving closer to the exchange there is not much that can be done.  Changing the SNR as above should help.
  • Latency – Another word for delay in this context.  It’s the round trip of your data.  For example, if you go out to get a take away pizza straight down the motorway it might take you 15 minutes to get back but if you go cross country down small roads with grass growing in the middle and lots of turns etc. then it might take an hour to get back even if the distance is more or less the same.  This is generally the case on the internet but some services can be routed down a prescribed route if the source and destination is known, for example voice calls (VoIP) are known types of data and can be routed more directly to particular destinations and back. Some latency your ISP can control and some they cannot. www.speedtest.net will give you a “ping” speed which is the time a piece of data takes to go out to a particular destination and come back to you.  It’s measured in milliseconds. 30ms is great, 50ms is still good, 80ms ok, 100ms+ not so good, 200ms+ definitely talk to your ISP.
  • Jitter – This how much latency varies so for example a general variance between 30ms and 60ms is not going to cause too much of a problem but if variance is between 50ms and 200ms then things like VoIP are not going to work very well as your broadband service in effect speeds up and slows down.  There are lots of reasons why this might occur and may be nothing to do with your ISP but you can ask. This problem could be within your local area network.
  • Packet loss – This is caused by some of the characteristics above.  Data is broken up into pieces called packets, sent to you and then re-assembled.  If some packets are lost due to noise on the line corrupting them for example then the data needs to be re-sent to you which slow things down.  If you went to Ikea to buy some flat pack furniture and a box was missing then you will have to go back for it which means it will take longer to put it together.  In the case of a real time services such as a phone call over the internet “sme its ight be missg” and a re-send will do you no good as by then it’s too late.

What’s left?

If you’re broadband service is still poor after all the above and maybe a few other checks that become apparent then maybe two broadband services using a load balancing router such as the Draytek Vigor 2830 series may be the answer.  At least you will get the benefit of 2 poor services combined which might then be satisfactory and probably more reliable.  It could be the difference between unsatisfactory and acceptable.

In my last blog I promised something a bit lighter than all this serious stuff and I have found something worth a mention.  In the blog following after this one I am going to have a bit of a rant about “Contracts – use, abuse and downright dishonesty”.

How am I doing?  Please help me to improve my blogs by commenting.


How do I choose the right broadband for me?


By now you will have got the idea that there are a fair few broadband options available and maybe you are not sure what to choose for your given situation.  One important question to consider; my broadband connection is important to me or it is not important to me.  I say this because if you access the internet occasionally at home and look at your emails a couple of times a week then some issues now and then with your broadband are not going to cause you too much distress but if you are running a business where your broadband is critical to it, it’s worth making sure you have good supplies and suppliers, and that you do your best to ensure continuity.

Before I get on with the “what’s right for me” bit I think it’s worth considering a few things.

BT, TalkTalk (who own Tiscali), Sky and a few others are the underlying suppliers of broadband and what I mean by that is if you change your supplier you might very well end up with the same broadband that you had before.  For example, if you have your broadband with TalkTalk and change to “Really Nice People Telecom limited” they might still supply you with TalkTalk broadband even if it’s branded with their name.

Another thing to consider is that behind the scenes telecoms is complicated, layered, fragmented and often process driven.  From my past experience working in telecoms and putting my finger in the air (so don’t quote me) around a third of all installations or changes go wrong in some way, from a minor delay to a full blown nightmare of a saga.  It doesn’t matter which supplier you use this can still happen, the big difference is how an issue is handled.  The vast majority of phone and broadband lines are installed by either BT or Virgin whoever you go through and this bit is not always easy to control.  A good and reputable telecoms supplier will take a lot of the burden away from you and deal with an issue as quickly as they can.  This means the difficulties of resolving an issue falls to them and even though they have special links into BT it can still be difficult for them.  A supplier with poor customer service like the ones supplying dead cheap broadband will sometimes have you pulling your hair out and other times will resolve an issue easily but you will have to drive things more either way.

In business a poor telecoms/broadband supplier can sometimes cost you much more than you save on a cheap service so pick your supplier with some care.

Let’s look at some scenarios:

In most cases here you might as well get the fastest ADSL available, it doesn’t usually cost any more.  Virgin may be different and charge a bit more for their faster broadband.  BT or LLU services (Local Loop Unbundled, where an ISP has their equipment installed in a BT exchange) are both fine.

The prices below are indicative and you may pay more or less.

All the DSL speeds below are “upto” speeds.  You are unlikely to get the maximum speeds when these services are actually installed.

I am a light domestic user who doesn’t use my broadband very often and if it didn’t work for a week then although it would be a bit frustrating I could live with it ok.

If this is all that you need then why not go cheap and just get the best deal from Sky, BT, Virgin, TalTalk, O2, Plusnet or another cheap supplier.  If something does go wrong the customer service might not be up to much, it’s pot luck, this is the downside of “cheap” but it probably doesn’t matter too much at this level.  To a point you get what you pay for.

Expect to pay in the region of £5 a month for the broadband, possibly as part of a line, broadband and calls package.

Example: 24mbs download, 1mbs upload, 3gb cap, 50:1 contention if relevant

A router will probably be supplied to you along with the broadband and should fine.

I am a relatively light domestic user who does use my broadband often AND if it didn’t work for a week then I would be really put out.

You don’t have to be a business user to buy business broadband so I would suggest a low end business broadband from a customer focussed supplier.

Expect to pay in the region of £15 a month upwards.

Example: 24mbs download, 1mbs upload, 3gb cap, 20:1 contention if relevant

I recommend a Draytek Vigor 2710 series router or a Vigor 2110 / 2130 if you want cable.

I am a heavy domestic user who does use my broadband often and if it didn’t work for a week then I would be really put out.  I download films, music etc.  I don’t want any limits on how much I download.

Buy an uncapped business broadband as fast as you can get for your location and with a low contention rate, no more than 20:1 (that is you share the service to the exchange with up to 19 other people).  10:1 is better.

Expect to pay in the region of £20 a month upwards.

Example: 24mbs download, 2.5mbs upload, uncapped, 20:1 / 10:1 contention if relevant

I recommend a Draytek Vigor 2710 series router or a Vigor 2110 / 2130 if you want cable.

I am a business user and although broadband is not critical to my business I want good customer service from my ISP, I want quick resolutions to issues where possible and a reliable service.  I access my business computers from home.  There are only a few staff.

Buy a low end business broadband.  Make sure you get a static IP, most ISP’s supply one for free and charge if

you need more.  This is a fixed internet protocol address assigned to you.  Look at it a bit like living in a house and having a permanent address as opposed to living in a caravan where your address changes (if you don’t have a static IP you getwhatever IP address your ISP gives you each time you connect to their service).  An example of a static IP address is “92.27.115.68”.

Expect to pay in the region of £15 a month upwards.

Example: 24mbs download, 1mbs upload, 5gb cap, 20:1 contention if relevant

I recommend a Draytek Vigor 2830 series router.

I am a business user, broadband is critical to my business and I want good customer service from my ISP, I want quick resolutions where possible and a reliable service.  If my broadband went down my business would suffer and lose money.  I am not a heavy user, it is mostly internet browsing and emails I need.

I would recommend buying a dual WAN capable router such as the Draytek Vigor 2830 with a Draytek Vigor 120 to put on the end of the second broadband connection.  You can then get 2 x low end business broadbands’ from 2 different ISP’s so if one ISP has problems the other will still work. 

You can additionally plug a mobile broadband modem into the Draytek Vigor 2830 if the mobile broadband signal is good enough where you are.  This means if your lines are cut by a digger working in the street for example the mobile broadband will still give you a service even if it’s a bit slow.

Expect to pay in the region of £15 a month upwards for each broadband and maybe £15 a month for the mobile broadband so perhaps £45 a month (excluding the cost of the lines).   Compare this to the cost of not having internet access at your business for a couple of days. Don’t forget the static IP’s.

Example: 24mbs download, 2.5mbs upload, 40gb cap, 20:1 contention if relevant

I recommend a Draytek Vigor 2830 series router.

Another advantage is that the Draytek Vigor 2830 will balance the 2 x broadband supplies for you so that you will get faster broadband.  Should one of them fail it will continue using the good supply, should both fail it will then use the mobile broadband whilst you get your line based broadband fixed.

I am a business user, broadband is critical to my business and I want good customer service from my ISP, I want quick resolutions where possible and a reliable service.  If my broadband went down my business would suffer and lose money.  We are heavy users, there are quite a few staff and we download some big files.

I would recommend buying a dual WAN capable router such as the Draytek Vigor 2830 with a Draytek Vigor 120 to put on the end of the second broadband connection.  You can then get 2 x high end business broadbands’ from 2 different ISP’s so if one ISP has problems the other will still work.

You can additionally plug a mobile broadband modem into the Draytek Vigor 2830 if the mobile broadband signal is good enough where you are.  This means if your lines are cut by a digger working in the street for example the mobile broadband will still give you a service even if it’s a bit slow.

Expect to pay in the region of £25 a month upwards for each broadband and maybe £20 a month for the mobile broadband so perhaps £70 a month (excluding the cost of the lines).   Compare this to the cost of not having internet access at your business for a couple of days. Don’t forget the static IP’s.

Example: 24mbs download, 2.5mbs upload, uncapped, 10:1 contention if relevant

I recommend a Draytek Vigor 2830 series router.

Another advantage is that the Draytek Vigor 2830 will balance the 2 x broadband supplies for you so that you will get faster broadband.  Should one of them fail it will continue using the good supply, should both fail it will next use the mobile broadband.

Now things move up a stage.  You could use four ADSL supplies with a Draytek Vigor 3200 or 3300 Quad WAN router which could give you something equivalent up to 96mbs download and up to 10mbs upload (you probably won’t actually get those speeds but it should still be pretty good) with the resilience of four supplies from upto four ISP’s.  The 3200 has a socket for mobile broadband as well.

Example: 24mbs download, 2.5mbs upload, uncapped, 10:1 contention if relevant

I recommend a Draytek Vigor 3200 or 3300 series router.

If FTTC (Fibre To The Cabinet, see previous blog) is available to you then a Draytek Vigor 2850 (the 2850Vn is available now, 2850n should follow in December) dual WAN router could give something equivalent up to 80mbs download and up to 20mbs upload (you probably won’t actually get those speeds but it should still be pretty good) with the resilience of two supplies from two ISP’s.  The 2850 has a socket for mobile broadband as well.

Example: 40mbs download, 10mbs upload, uncapped with possible guaranteed throughput after survey.

I recommend a Draytek Vigor 2850 series router.

Another possibility is EFM (Ethernet First Mile) which is several broadband supplies combined into one as described in my previous blog.  Better SLA’s (Service Level Agreements) and guarantees may come with this.

Example: Up to 20mbs download, upto 10mbs upload, uncapped with possible guaranteed throughput after a site survey.

I recommend a Draytek Vigor 2930 series router.

You may also at this stage want to consider a leased line backed up by a high end ADSL which could give you between 10mbs and 100mbs both up and down guaranteed with a high end SLA.  I am not going to go into too much detail except to say that these lines cost from around £500 a month.  The higher end ADSL type broadband such as FTTC may give nearly as good a service as a 10mb leased line so I would probably start to look at leased lines if I needed 20mbs both ways or more.

With all of options in this section you are probably best consulting an IT professional in house or contracted to decide the best option.  If you are an IT professional reading this then you probably know a lot or all of this already.

I may be able to help you or it may be best to get an IT/network audit performed to help you decide.  I will make some recommendations for a situation if I can.

I recommend a Draytek Advanced Networking product or Switch.

VoIP

I think a special note for VoIP (Voice over Internet Protocal), that is running your phones over broadband, is needed here.

Unless you are making just one or 2 calls at the same time it is better to keep the broadband used for VoIP separate to the broadband used for data.  In fact it’s better to keep it separate full stop really, it avoids conflicts.

For this you want a consistent broadband service.  SDSL can be good for this and can support up to 20 high quality calls at the same time or 40 low quality calls. Typically at upto 2mbs both ways with a low contention ration and QOS (Quality Of Service) added to it.

Some business ADSL services have QOS (Quality Of Service) attached to them that makes sure calls get a higher priority and some avoid using the internet as much as possible by routing your calls straight through to where they need to go.  The lower a contention rate broadband has the more consistent it should be.

Leased lines are fabulous for VoIP especially the latest ones where you can reserve a portion of the “pipe” for calls only.

How long does it take and what do I need to do?

So now you have chosen what you need and want to know what will happen after you order it!

When a BT engineer comes to install a line or fix a fault they will usually specify a morning or afternoon slot, that is 8am to 1pm or 1pm to 5pm.  You can get your supplier to pass on instructions to them such as a phone number to call before they visit you but there is no guarantee that an engineer will see or follow those instructions.  If BT cannot get access to do their work and they have to go away they may charge you for it so someone needs to be there even if they have to wait around for several hours.  There is no 100% guarantee that BT will turn up when they say they will but they do more often than not.  They base their appointment attendance on average times so a few too many long jobs will make them late or come the next day, you should be informed if this is the case at some point.

If you are having a new line put in for broadband it takes between 10 and 20 working days before the broadband starts working.  Depending on the type of broadband it may take 10 days to settle down to an optimal speed.

Putting broadband on an existing line or changing broadband supplier will take up to 10 working days and it is unlikely that a BT engineer will need to visit.

Allow at least 10 working days for FTTC installations.

EFM installation times are probably subject to survey but are normally around 26 working days.

Leased lines usually take up to 3 months, they are subject to survey and there are several stages to an install.

What do you think so far, are these blogs useful, are they easy to understand?  Please comment or I won’t know and won’t be able to improve them if that’s what they need!

Well, I think that’s enough for now!  Next time, “How can I get more from what I already have?” and perhaps something lighter and more amusing.  To be continued …
