Probably fastest deployment of DOCSIS 3.0 yet
Tuesday 07 April 2009 11:34:39 by Andrew Ferguson

Monday saw a number of places parade a 160Mbps cable broadband service as the worlds fastest broadband, but we recall there being news of 1Gbps being available in parts of Japan.

KDDI offers a symmetric 1Gbps service for around £40 a month, but it only has limited availability. The news of a 160Mbps connection seems somewhat dull in contrast, but this was picked up due to the service using DOCSIS 3.0 which is the technology Virgin Media is using for its 50Mbps product. Virgin Media has hinted that it can increase speeds, but for this to happen the remaining analogue TV channels will need to be switched off to allow for bonding.

Speeds of 1Gbps into the home while sounding exciting bring other issues. Sharing this between multiple computers can be fun as home routers have trouble coping with 50Mbps connections sometimes and Gigabit network connections on computers are still far from standard. If you use a wireless connection you will also be limited by the speed of this before that of your broadband service. There is also the issue of whether people will ever actually get data at speeds of 1Gbps. Many websites are still hosting on 100Mbps links in datacentres, though the most likely bottleneck will be where 100's or 1000's of 1Gbps connections aggregate onto the backhaul network.

For those bemoaning the price of the Virgin Media XXL product at £36 to £50 a month, they can afford to charge a premium price in the UK as they have little competition at this speed point. Hopefully in two years with competition increasing as FTTC appears ,the pricing may be more competitive. Lower pricing is a double edged sword though, as the usual way to lower pricing is to increase contention or introduce other limits.

They have this already in Poland http://www.vector.com.pl/en/article/51174_The_first_deployment_of_the_DOCSIS_3.0_I-CMTS_in_Poland.htm

Backhaul is a major issue and has been for years for some networks that neglect their peering points and let them get hwavily congested to the point where traffic to many destinations simply stops flowing.

Better congestion in the backbone where it can be managed than the access network where it is usually somewhat less graceful.

Not sure which networks you've worked on, but the ones I have transit and peering wasn't neglected, though one of them has been neglecting things since.

@evector - Pre-DOCSIS 3 and DOCSIS 3 networks have been in deployment since late 2007. The Japanese deployment is unique in that it'll be utilising upstream bonding which is a first.

It's all progress, so power to those that are doing it, including good old OZ. It is making the rural urban divide even wider though, I hope Lord Carter is paying attention on his Easter break...

Lord Carter is probably busy reading PR magazines and contemplating what to have for supper.

Im just happy to see that when fibre becomes mainstream its likely many of us will have an alternative choice to BT and their so called fibre. I guess for us in the UK so far its H20 or Virgin as alternatives but it looks like other schemes are slowly being developed.

Like VM and their so called fibre which is actually FTTC.

Like for like with BTs service than is it not?

I don't see BT trying to claim that it's not copper between the cabinet and house, though, Carpet. Which VM do.

Really so when FTTC becomes mainstream throughout the UK from BT you dont think they will sell it as a fibre service?

Simply using the term FTTC would seem to show that BT have a grasp of the difference, yes.

If BT called their service fibre and its only FTTC than its really no different to virgins service... A bit of fibre to a cabinet, something entirely different into your home. Grasp the difference??? Id say its more a copy the liars.

They haven't called FTTC "fibre", though. VM have. While this might change, BT have freely accnowledged that it isn't fibre all the way.

BT do tend, generally, to be more realistic than VM over advertising terms if you hadn't noticed...
Posted by comnut over 7 years ago
I think BT is trying not to sound like VM...

The only diff. is that VM send COAX from cab to premises, and BT often use the *ancient* copper/ali twisted pair...

sure, it can be called 'copper', BUT its the same stuff that gets quality HDTV to your sat receiver...

Stop defending BT you sound stupid, if they are not going to call their future FTTC services fibre what do you think they will call them? BTs planned service is no different to Virgins, simple plain bending of the truth.

"BTs planned service" ??? heh, I may believe that when BT start routing coax to the premises, like VM do.... :D

"BT do tend, generally, to be more realistic than VM over advertising terms"

including the * footnote that tells you how much MORE it will cost, and how long you will be trapped in a contract, that 'renews' if you are not quick enough to cancel early enough....

According to away with the fairies BT supporters it will be ok for BT to call that fibre while at the same time in the past deeming Virgins service not to be fibre.
Maybe im missing their logic...... Or blinkers

Listen to people like Dawn_Falcon and every provider apart from BT are useless. He/She/(maybe IT) seems to think LLU is terrible, Virgin media is terrible and anything that doesnt contain 30 year old multiple joined stringy bits of copper and Alu should be outlawed, thank got the rest of us live in the year 2009
Posted by Dawn_Falcon over 7 years ago
No carpet, in your mind you think that somehow the fact I've stated that BT haven't called the service "fibre" translates to the fact that I have.

Well, I have't. And no, LLU is not "terrible", it's simply based on an government-imposed economic model which has held back broadband development in this country by five years

The only comment you made there which resembles reality is that I consider VM terrible.

What do you think BT will call their FTTC services then? Are you seriously trying to state they wont pull the same stroke as VM and tag glossy adverts with the word "FIBRE"? Im so confident they will id lay cold hard cash on it right now.
