Re: ntl Confirms 10Mb Broadband Speed Increase
an upload of (upto) 1.3meg sounds very appealing.

Just checked there Address checker. March next year :Yikes: . 2.2 km from the exchange which should give me between 9 to 14 meg. Hardly the 24 that they are saying. But they get away with that by saying up-to :dunce: . Still i am happy with what i have :). Wonder how long before there is a www.behell.co.uk Silly me i forgot i just registered that name :LOL: |

Fastest usable data throughput you'll see on Be or any other 24Mbit ADSL2+ service is around 21.5Mbit/s download and 1.1Mbps upload. In the interests of fairness though and by the same token you're unlikely to see 10Mbit 24x7 on cable, already some Telewest customers who have been upgraded to 10Mbit have reported seeing less than 5Mbit most of the time with the odd spike into the 7Mbit territory. Being honest if I have a choice between ADSL2+ and cable if I'm close enough to the exchange I'll take 2+ every time. My 21.5Mbps would be aggregated onto a gigabit, whereas cable you're dealing with a 10Mbps slice of 38Mbps, the statistical contention works much better on DSL2+ as the contention point is further down the chain. Anyway isn't this conversation about ntl? :p: |
Re: ntl Confirms 10Mb Broadband Speed Increase
Well Checking my line here shows maximum of 2mbs from anyone. :(

If I move I have to do behind my landlord's back plus the following. Pay for BT line install Pay for ADSL install Pay £27.99 for the package I want. Keep NTL line active as I want the tv. Pay for BT line removal when I move out. So amongst spending tons of money on installation/removal I will be paying 2 line rental's and increasing my monthly expenditure. This example is just for me but its not as cut and dried as you think to just simply leave NTL. I have no aerial on the roof either and there is no way I could get away with a sat dish the landlord would almost certianly notice that. __________________ Quote:

Re: ntl Confirms 10Mb Broadband Speed Increase
I believe this is the difference...
when you're on cable you're contended at UBR level sharing a smaller pipe whereas when you're on ADSL you are contended further away (at the exchange). so cos you're further away you're contended on a larger pipe (but with more users). __________________ nb. if 10meg users end up contended on a 38meg pipe then we're screwed, aren't we? |
Re: ntl Confirms 10Mb Broadband Speed Increase
maybe we should start a vote on why people stay with NTL.. happy with service.. like the price.. can't get another ISP provider etc

They could provide a service that provides that if only one user is connected but you only get half of that if two are connected or a tenth of that if ten are connected. The statement is still valid even if no one could ever achieve the speed unless they were the only one connected. |

In my opinion this is a very unfair comparison as with the Be and UKOnline services, as with all DSL services, the maximum speed is limited by line quality and length which isn't an issue with active cable networks. The 10Mbit that ntl and Telewest advertise is also a maximum 'up to' speed which is governed purely by bandwidth utilisation rather than by line length. However the advantage that Be and UKO have is that they can purchase a 1Gbit connection from the exchange to their backbone, multiple if required, whereas ntl / Telewest are only able to offer 38Mbps shared to each area. Apples and oranges it is indeed, but then so is comparing distance limited bandwidth and contention limited. Unless you can change the laws of physics of course. I'm not being a fanboy or a hater I'm just setting out the facts as they are here. Contention bandwidth wise will be a plague to cable networks for the foreseeable future and distance limitation to DSL based broadband services and that's the nature of the beasts. |
Re: ntl Confirms 10Mb Broadband Speed Increase
But when they remove the analogue channels they will have loads of network capacity to be able to resegment ubrs and offer many more 38mbs channels thus lowering the contention.
|
Re: ntl Confirms 10Mb Broadband Speed Increase
Quote:
Resegmentation itself isn't a magic bullet as it can be massively expensive especially when having to split nodes, pull fibre and build new cabinets. There are only so many nodes that are combined to each card and once you're down to a node a card it starts getting really expensive. As I said, foreseeable future :) There's also the cost-benefit to consider, how much are you going to break a network down. It still also is unavoidable that 4 10Mbit users can saturate their area, all you can do is minimise that possibility by breaking down to as small an area on each card as possible. |
Re: ntl Confirms 10Mb Broadband Speed Increase
Out of interest roughly how many people, on average, are there per area?
:edit: That didn't make much sense. I mean how many people is that 38mbit shared between, on average? |
Re: ntl Confirms 10Mb Broadband Speed Increase
Hehe varies a lot, and I'm not at liberty to divulge node sizes or homes passed per card due to ongoing NDA :)
Piece of string question really, in student areas not many due to their hunger for the bandwidth :) |
Re: ntl Confirms 10Mb Broadband Speed Increase
if NTL advertise their contention level as 20 to 1 then the top tier is 3meg so a 38meg pipe is shared by the equivalent of approx 250 3meg as an example.
and it takes 13 users or more running on max for speed to suffer. if they're all upgraded to 10meg then the pipe has to be shared by a max of 76 10meg users - and it takes 4 users or more running on max for speed to suffer. __________________ conclusion - we're screwed! |
Re: ntl Confirms 10Mb Broadband Speed Increase
Yeh but no but, this is why file sharing is the crippling to a network as it results in constant traffic, so if each of those 76 users is file sharing then you're screwed.
Everything else is very bursty, a web page here, a ftp there, a VOIP over there, all this traffic fits in for the few ms it takes to transfer those packets of data. 76 people sharing a 38Mb connection, many office infrastructures have more users that that sharing 10Mb over a floor with only backbones etc at 100/1000Mb. The contrarian view is that these users now they are on 10Mb will shift the traffic they need to accross the network faster and thus create less of a bottleneck at the UBR. |
Re: ntl Confirms 10Mb Broadband Speed Increase
what about when NTL compete with these LLU 24meg companies and release a 24meg product! all it takes then is a couple of 24meg users maxing out their 38meg pipe and things start to contend big time?
|
Re: ntl Confirms 10Mb Broadband Speed Increase
Thats why that'll come around when the new tech is available to be used. Never can say I've heard of a 24mbit cable ISP?

Re: ntl Confirms 10Mb Broadband Speed Increase
Something which has not been discussed or clarified is ntl's mention of the speed boost button (SBB) in their 10Mb upgrade plan.
This would appear to indicate, to me at least, that the future normal speed will be somewhat less than 10Mb until the SBB is clicked. Presumably, clicking the SBB will only boost the speed for a set amount of time otherwise everyone would run at full speed all the time, additionally, I would expect that you will not be able to boost the speed again until the current operation has finished, or a set time has elapsed, otherwise it defeats the object of the SBB which is obviously designed to conserve bandwidth/allow more connections on the pipe. Another thought is that the SBB would only be available to you until such time that you have used up your cap whereupon the SBB would be totally disabled, this would confirm the previously mentioned statement by ntl of dropping users to a lower speed when their bandwidth is exceeded. If the above assumptions are correct what is the base speed going to be set at, even setting it at 512kb would still allow ntl to advertise the service as †œup to 10Mb/sâ₠ÂÂÂ. |

Re: ntl Confirms 10Mb Broadband Speed Increase
based on their own rules (ie. the contention ratio of 20 to 1), if they put (for example) all 10meg users on a 38meg downstream then they will have to limit it to 76 users. alternatively they could bung more users on and revise the contention ratio they use.

can you point to where they specify 20:1 as I have never seen ntl advertise a contention ratio.

Well if you work it out this way, max possible download on 10mbit = 3200gig, cap of 75gig on £37.99 then max traffic possible equates to 43:1 contention ratio and thats on the top tier.

Re: ntl Confirms 10Mb Broadband Speed Increase
My friend in Bothwell got his upgrade not the 10MB but free from 512 to 2MB uncapped and could not be happier. Iâ₠™d accept this tier on my NTL. 10Mb is too much for me a steady 2MB would be great.
This merger could speed up or slow down NTL upgrade. God there will be a total re-branding and name changing |
