Next upgrades.

Because it's easy, you just tick a few boxes on a GUI.

How do you know there isn't any taffic shaping going on or monitoring at UK Online for a FACT?

I said none on the LLU which is quite different to none full stop. If there were shaping on the LLU network I'd know because I'd be working on it. (The joys of contracting)

Why did he receice the letter then and had his speeds reduced to 200kb/s? for newsgroups and torrents. If I need to I will ask him to scan this document and post it to me to show you. He was actually downloading at 200kb/s till he got a work around for it.

The amount of workarounds is very limited and changing ports isn't one of them. People weren't throttled to 200kb/s, there is global shaping on the non-LLU platform which is dependent on the bandwidth being utilised by these protocols. Customers whose usage was targetted specifically were not throttled to a set rate in any way but were given a strict contention ratio.

Sorry but you are wrong because my friend HAS one of those letters for high utilisation with a LLU

Considering it's not being monitored it's not likely. If such a letter were sent it would have referred to non-LLU connections he might have had.

Well what happened to Mr Insightful?. I'm sorry for being cheeky but I've already mentioned my friend has this letter. If I bloomin' read about it in the paper, fair point but no I didn't. Well it seems that UK Online is doing it ALSO. FACT

Again I didn't say that they weren't doing it at all just that they weren't doing it on LLU.

I apologise for that scare I was just worried as what I was downloading was running about 200kb/s and after what happened to my m8 made me paranoid. Was a "just incase".

You're welcome.

Since this topic is meant to be about speed upgradesi thought i post it here, i have bene looking on telewest maintenance page and recently they have been doign a lto of network upgrades and doign upgrades to the ubr's nto jsut in my area but nationwide do you think this is the start of potential upgrades to teh speed in some way?

Not really, constant upgrades are needed anyway in order to maintain capacity for the current customers, also the more capacity that's free the better the performance.

Ex-Telewest areas are currently upgrading their upstream paths to allow them to fit more customers onto the same hardware.

Telewest didn't as a rule do big upgrades unless customers were complaining however these upgrades aren't necessarily major.

They may be looking at an increase in upstream capacity to match up with ntl's deals and get the 512k upstream on the 10Mbit product.

Rumours are also abound of a 15 - 20Mbps service being released to compete with ADSL2+, however this could prove challenging to support on an unlimited basis especially as customers would expect and demand at least 1Mbps of upstream on such services.

It's very tricky to guage exactly what ntl are up to. In the US the cable providers there compete solely on speed and are ahead of the DSL operators. Here the cable operators aren't number 1 for speed or price so it's tricky to figure out where they are going.

i suppose that true, i just thought the ubr is what determines the speed ie if they can only have a max of 100mb (just random figure nto meant to be real) then with 10 people on 10mb they be at max capacity but if they wher eto upgrade it to 1gb (another random number not real) then they could say have 20 people on 50mb

but when i had the enginner install my tvdrivve 3 weeks ago he meantioned when i asked that telewest ar eflaling behind adsl2+ and are planning on try to top it somehow including making the u;pload speeds higher , so it that why ia m guessing it might be happening witht he upgrades

btw telewest is still operating indepently of ntl (for internet and tv) but will soon be under the new name i think. from what the engineer told me they want to merge the 2 networks together but it wether the costs will be worth it and they could save mroe money on it merged and that depends on the high acrtie to decide even they dnt know yet

Ah you can't just upgrade the uBRs beyond a certain point. Under the current standards no local area can be supplied with more than 38Mb downstream capacity and 6 x 9.6Mbit/s upstream capacity.

When that isn't enough you can add more downstream channels, which Telewest do, up to a point. Think Telewest only run up to 2 downstream channels at the mo, so that's 76Mb/s downstream and 57.6Mb/s upstream available to a local area.

Please note that pings and speeds will get shaky with 40Mb/s or less of upload used, and that it's very difficult to have all 6 upstreams equally balanced for load so you're probably talking 30 - 35Mb/s of upstream available before some customers begin to notice issues.

At that point you have to do the big upgrade, network resegmentation which consists of splitting a single fibre optic link into two links so that an area that was fed from a single fibre link is split into two areas with fibre, then Telewest would have the capability to supply the 2 x 38Mb/s and 6 x 9.6Mb/s to each of those areas.

The difficulty of resegmentation varies between a little irritating and taking days right up to having to pull new fibre in and taking weeks.

ok i unndeerstand a bit bette rnow so the ubr doesnt have much infulance on teh speed well that how i interupt it, if it max of 78mb how do telewet plan on giving 50-100mb to people like they annouce in thee report i think thi year? unless part of it to do with the docsis?

Totally new system which involves completely replacing the existing uBRs and/or cards and will require new modems for customers to take advantage AND can only be done in purely digital areas.

The uBR doesn't have that much influence it's more how many homes each one is feeding that's the major thing.

I'm sorry about the post before James Henry. I thought you were calling me a liar and that my friend hadn't received any letters for high utilisation. So I spat the dummy out. lol.

As for what software/hardware ISP's would use to shape traffic, not got a clue. Thats why I asked if it would be easy to use without messing with other lines (which was stooooopid of me saying)

You do know your stuff and have a lot more knowledge on this networking side of it. Again I apologise.
