5Mb the magic number
 

5Mb is the average speed a person on the 20Mb will get when they are on an overloaded UBR.
I find this very suspicious. almost as if it's not coincidental but deliberate.
who needs STM when you can use other rules?

Re: 5Mb the magic number
 

indeed

Re: 5Mb the magic number
 

I used to get 5mb constantly on my 20mb line after 6pm for over a month when my problems started, but for the past 3 months I usually get between 0.2 & 2mb until 11pm.

Neighbours & friends around the corner exactly the same, we are hoping the forthcoming reseg finally helps us.

Do you know what else I've noticed?
when someone asks support if they are being STMd or on an overloaded UBR, and they ask them in a way that you know they're going to kick off if support say yes you are STMd outside of the official times, or yes you are on a congested UBR. why do support always say No you're not STMd or no your UBR looks fine from here, it's currently running at less than 2% capacity.

:D

Figures to back this up,times, dates...source?

I'm on a particularly busy uBR, and I used to live in student territory, but I see good speeds almost daily, often above 14Mb at peek times.

Re: 5Mb the magic number
 

Asking for figures to back up an observation is just plain silly.

That's nice. did I say particularly busy. or did I say overloaded?

Re: 5Mb the magic number
 

5mb seems high for overloaded ubrs to me :p:

Re: 5Mb the magic number
 

I know. between 0.2 & 2Mb sounds more like it :D

Re: 5Mb the magic number
 

My particular case was weird, it was fine for over 8 months - constantly 18-20mb every night, then one weekend it suddenly droped to 5mb & pings of about 200.

Then I rang lots of times over the following month as the speed never went above 5mb after 6pm (was always just under 5mb). I was told they'd only added 3 more people and the UBR only had 80 people on it so was not over subscribed.
The following 3 months it drops to 0.2 to 2mb every night after 6pm & im told its an over subscription issue. - hence why they refunded my £30+ last month.

All my neighbours suffer exactly the same.

The weird thing to me was when it intially started droping to 5mb every single night after 6pm, id of thought the speed would of gradually droped over a matter of weeks as more people got added... but no it droped straight from 20mb to 5mb on a friday night & carried on doing that every night that month.. then the following month its the dredded 0.2 - 2mb after 6pm (for the past 3 months).

Reseg hopefully next wedneday/thursday so fingers crossed if it is an oversubscription issue - it gets fixed finally.

Re: 5Mb the magic number
 

Oversubscription on cable is a tricky beast to predict, especially with the pipes being so small relative to the top tier of service available.

I'm not sure about 5Mbit being the average speed people see, I've seen everything from 14Mbit as mentioned by Toto right down to sub-1Mbit. It's all about how much bandwidth is available at the time.

I'd hold off theories until I can build a definite pattern.

If you have a set of data you've built this observation from please show it, would be interesting to see. I presume you built it up from observing things, what are they?

Re: 5Mb the magic number
 

Silly?

I hardly think so, I thought it was a reasonable request, as I assumed you had the data to back up your observation, but if you don't then fair enough.:shrug:

Re: 5Mb the magic number
 

Good idea. that's why I never do them.

Not for someone's observation. I am going to do you a favour and ask Virgin what the average speed is for a user to have on an over subscribed UBR. could be interesting as to what the actual figure is.


If the average speed is 6.13Mbps, then I think me saying 5Mb is a bit optimistic for an overloaded UBR I think. but you have to think that some of the results obtained to come up with that figure of 6.15Mbps would have had to have been given from a percentage of users that were on an overloaded UBR.

if you think that to obtain a figure of 6Mb from the use of 10Mb and 20Mb. then what does that work out as an average?

Re: 5Mb the magic number
 

Given that something like 80% of users are on the 2Mbps profile, if users are averaging 6.15Mbps, it just shows how good the higher speeds are.

ps. Can anyone tell me the name of an overloaded UBR? I want to check something.

Re: 5Mb the magic number
 

So 20% are on 10Mb and 20Mb?
what's the average speed an O2 ADSL person is on would you say? considering that it's a copper connection and not fibre optic I'd hazard a guess of around 7Mb?

Be. top possible speed has got to be around 22Mb if you live in the exchange and again is a copper connection and not fibre optic. (Virgin tell us that copper is useless remember) I'd say the average speed was again around 7Mb.

So we have
Virgin - 10-20Mb FIBRE OPTIC - 6.13Mbps average speeds obtained
02 - 7Mb COPPER - 5.32Mbps average speeds obtained
Be - 7Mb COPPER

Virgin won by just under 1Mb. you're right the speeds are very good for 20Mb fibre optic :D

27% oversubscribed apparently.

Apolagies if thats not what u ment.
