Cisco drives nail in music industry coffin with CRS-3?

Tuesday, March 9th, 2010

Most people won’t have given much thought as to how their email gets from A to B or how that video arrives from YouTube.  It just comes down the broadband connection which is plugged into the router next to the phone (or somewhere like that). Right?

Well today the worlds biggest router manufacturer, Cisco, announced their latest and greatest product.  It isn’t something that you will want to plug into your phone line though because it would take up most of the living room and there wouldn’t be enough room left for the sofa.

It would also be a bit of an overkill because this router, the CRS-3, is powerful enough to handle up to 322 Terabits1 per second, which  is roughly a hundred million times faster than the average UK broadband connection speed!

Bandwidth bandits – the story continues with the GoPro HD Hero

Wednesday, March 3rd, 2010

I have been raving about the Kodak zi8 but now enter the GoPro HD HERO stage left. This is a headcam that Ben, our head of NetOps, has bought this month to go snowboarding. Instead of holiday snaps he wants memories in 1080p HD on YouTube that all his mates can watch when he gets back. Black runs, off piste (on piste) etc etc etc.

This short 60 second video is a paltry 44MBytes. It’s a bandwidth bandit though because who knows how many fans (more…)

Kodak and YouTube are burning up your bandwidth

Tuesday, January 5th, 2010

Since I got my KodakZi8 in mid November I’ve been videoing – not a surprise. The statistics however are startling. In that time I have recorded around 13.3GB of HD video – all of which resides on my hard drive.

I have also uploaded 26 of these videos to YouTube with a modest 616 total views. I’m not sure what the average size of video is but a rough guesstimate is 1 minute and 100MB. This suggests that my videos on YouTube account for around 61GB of data download in around siz weeks (and 2.6GB of my own upload bandwidth). Let’s assume everyone has a YouTube account and is like me. In this case everyone will be downloading this amount of data. Ok I know they are not all doing it at this time but it certainly points to the future.

As a sanity check I looked at my own ADSL usage in December – 67GB!

Video is going to change the rules when it comes to growth in use of the internet.

First 100Gbps commercially available optical network rolled out by Nortel and Verizon

Tuesday, December 15th, 2009

Nortel yesterday announced that Verizon had implemented the first commercially available 100Gbps network on a 893km link between Paris and Frankfurt.

There are several significant (or at least  I think they are interesting) points to be made regarding this milestone.

First of all Nortel is clearly a leader in Optical technology, as it is in a number of its other areas of business. 100Gbps has been discussed at the last few meetings of the London Internet Exchange (LINX) but largely in terms of the fact that 100Gbps equipment has only been achieving 40Gbps, an interim step.

It is a crying shame that the mismanagement of the business during the earlier parts of the decade resulted in the Chapter 11 situation we now see today and the break up of the business. From Timico’s perspective this is at least focussing minds at Nortel and we have seen a significant improvement in responsiveness and keeness to get things done. Good I suppose.

The 10Gbps standard was ratified in 2002 and, doing a quick trawl the first network rollouts seem to be around 2005 -  this is the case at LINX who tend to be up there amongst the leaders. Truth be told it was probably earlier than this.

The 100Gbps standard has not yet been ratified so there are clearly commercial pressures and advantages to running with the technology for a commercial operator to push ahead with it. Historically this has been 4x the cost for 10x the throughput. So it is clear that the cost of bandwidth is going to continue on a downward trend the more people use it, which they are doing.

This is an interesting wave for ISPs and network operators (surfers) to be riding.  We have to be nimble atop the big rollers making sure that we keep our network costs down quickly enough to match the competitive pricing pressures of the market place.

Zi8 is a stunner and will drive internet bandwidth usage

Wednesday, November 18th, 2009

Following on from the Jeff Pulver #140 Conference in London yesterday I’ve been trying out a new toy.

This is the Zi8 HD digital video camera by Kodak and I have to tell you it is a stunner. Presented to me yesterday by Jeffrey Hayzlett, CMO of Kodak the HD video quality is outstanding and it is extremely easy to use.

My kids have already latched onto it and started playing with it though rapid adoption by children is not necessarily a pointer to how easy a gadget is to use – technology comes naturally to them.

The camera facia comes printed with the YouTube and Facebook logos, which is a strong enough hint for even the dumbest of users.

I’m not going to bore you with the camera spec. What I will says is that the 75MB of the 59 second video below is well within the 2GByte allowance that YouTube gives for a single video!

The video is presented below for all to see. It’s no professional production and I note that I should have combed my hair first – I’m desperate for a haircut. That’s showbiz folks.

The Zi8 is groundbreaking and although I’m no expert I have no hesitation in recommending it after just a short test.

You may have noticed that this blog doesn’t major on gadget reviews.  The point here is that this another contributor to the growth in bandwidth usage as people start to upload more and more HD footage to sites such as YouTube. What goes up once of course gets downloaded many times, assuming it is any good. It’s a worry for those of us having to manage ADSL backhaul bandwidth but that’s progress for you.

LINX67 15th birthday meeting – the internet continues to grow

Monday, November 16th, 2009

A milestone for the London Internet Exchange with its 15th birthday meeting today at Goodenough College in London. These are seriously useful meetings of like minded souls from the internet industry.

The internet is run by geeks that work extremely hard. In fact they live and breathe technology on a 24 x 7 x 365 ¼ basis and these LINX meetings bring them together for long days of meetings and presentations but also long evenings of letting their hair down.

LINX meetings are quarterly. Since the last one in the summer the peak traffic on the LINX network has grown by an incredible 25%. If the trend continued that would mean more than doubling in a year. The traditional perceived wisdom for growth in internet usage is 50% pa which is close to what I see on the Timico ADSL network.

LINX’s growth has been fuelled by an increase in membership of around 15% this year though clearly that wouldn’t account for the proportional increase in bandwidth.

For geeks everywhere who believe that size does matters the LINX network currently has over 2.5Terrabit per second capacity. The organisation is clearly providing value for money which is why all these new members are knocking on the door.

A year ago I seem to remember a statistic that said that 65% of the internet was reachable via LINX peering. Now this has grown to 70%. This is good news for end users as it helps to keep prices down.

Interestingly 75% of new members are from outside the UK, including a fair number from Russia. The UK is becoming increasingly an important place on the internet map.

More snippets from LINX67 as I think of them. The meeting is absolutely packed.

shock horror – high performance laptop costs $100m

Thursday, November 12th, 2009

Did you know that a state of the art supercomputer costs $100m?  The price never comes down with time – the speed just goes up. Today’s leading edge box (actually it’s a datacentre full of racks, not a single box) has over 1Petaflops of processing power.

Such is the progress of technology that in three years time this will not even be in the top 500 of supercomputer performances. At that point the maintenance costs also start to ramp up so your average supercomputer owner just bins it and buys another one. It’s what I’d do :-)

What is also interesting is that today’s supercomputer processor speed flows down to the laptop of 12 years hence. So in 2021 you will get one hell of a bang for your buck. Whether you will need that much power to send emails and operate Word 2021 (or whatever it will be called then) is unlikely.

I guess the power will be usable for improved 3D HD graphics for gaming and TV but I’m not sure what other apps will need it.  Whole brain simulations on a laptop perhaps.  Build it and they will come…  It does point to a huge continued growth in network bandwidth usage.

Of course the laptop won’t cost $100m. I just put that in for effect! My guess is that all laptops will come free with subscription to network services.

what type of traffic uses up broadband bandwidth

Thursday, September 10th, 2009

It is interesting to see the mix of traffic on the Timico ADSL network and thus what is taking up the bandwidth usage. As a B2B ISP the profile will be dramatically different to that of a consumer provider.

For example the amount of bit torrent traffic is fairly low at around 6%. This compares with up to 40% sometimes seen on residential ADSLs. There are legitimate business uses of P2P but it does suggest that a few customers are hitting it hard. The nature of P2P is that it will hog all available bandwidth which actually makes it a highly efficient protocol for transferring large amounts of data. In fact the 6% of P2P traffic on the Timico could well be largely down to half a dozen ADSL2+ customers hitting it hard which represents a tiny proportion of our customer base.

The usual business type applications such as email and VPN are apparent on the chart but the biggest driver is clearly simple web browsing. No great messages here regarding bandwidth growth.

There are however some hidden gotchas. This chart was a snapshot over one working day sometime recently. It does not, for example cover the Ashes cricket matches where video streaming saw a huge growth as people at work tuned in on Skyplayer. How many business managers knew that their staff were watching the TV all day instead of working?  It is costing them twice – in the salaried time spent watching the cricket and in the cost of the bandwidth.

Also it is daytime usage and does not cover night time where a significant amount of file transfer traffic takes place. We do see a small rise in P2P in the evenings -  Timico provides thousands of corporate homeworker ADSLs. However the overall bandwidth falls significantly for us after 5 o’clock which is the exact opposite to what is seen in the consumer world. It will be interesting to periodically track the changes in usage and look at where the trend takes us over time.

bandwidth bandit – off site backup case study

Thursday, September 3rd, 2009

One of the big drivers for bandwidth usage is offsite back up and storage.

The amount of backup and storage capacity required by a business is to a large extent dependant on the nature of that business. An organisation which regularly processes a large amount of financial transaction or billing data is going to need a lot more than somewhere whose main concern is the safekeeping of CRM data and perhaps the security of information on individual PCs. Moreover as a rule of thumb the larger the amount of data that needs backing up on a daily basis the more critical that data is likely to be for a business.

One of Timico’s customers performs a 50GB daily backup to tape. The tape is removed from the premises every night to an offsite storage location. This is far from ideal. The company until recently operated over a bonded ADSL connection which gave them approximately 2Mbps uplink.

Backing up 50GB over the 2Mb connection was going to take 555 hours. This was not a practical proposition. The company has just put in a 100Mb leased line. The time taken to perform the backup would now be 11 hours which makes an overnight run a real proposition.

Not everyone has a 50GB requirement but as faster broadband technologies come along at cost effective prices more and more people will use an offsite on-net backup facility which will in turn drive bandwidth usage.

The chart is self explanatory. I’ve made some assumptions regarding packet overhead on the pipes

Bandwidth bandit CCTV

Tuesday, August 18th, 2009

One of the applications rolled out as standard when people are trying to promote the use of faster broadband is Closed Circuit TV. I’ve always treated this with some contempt as a poor contribution by some unimaginative marketeer somewhere desperate to think of reasons why someone should upgrade their connection.

In the interests of pursuing the theme of bandwidth bandits I was however prompted to look into CCTV as a subject. I am amazed the progress in this space. 

Timico uses a product called X-Protect.  Cameras plug directly into the LAN and are powered by Power over Ethernet.  The product supports a number of codecs including H264 and MPEG-4 and you can select the quality of your stream based on how much bandwidth you have.

As an ISP with a high bandwidth Gigabit fibre based WAN Timico has plenty of bandwidth and our cameras stream at an aggregated 10Mbps to the recording server.  Timico IT staff can view these streams from anywhere in the network, including from home and including on the move with their PDAs.  The bandwidth used for viewing from outside the network does not of course have to be the same as on the LAN/WAN.

What this does show though is an application that is promoting high bandwidth usage.  Manufacturer Milestone Systems states a recording capacity of 960GB per day per server.  A quick back of a beer mat calculation suggests this would need a total of around 90Mbps streaming to support this capacity.

The only way is up for bandwidth usage.
