Re: Effect of IP profile and how do individual ISP's use it

BT's BRAS imposes the IP profile, whether or not an ISP chooses to use it to regulate the traffic flow they send to the BRAS.

Correct - the BT limit still applies, but we don't copy it across to anything to apply it on our side too.

Phil.

Then I think Plusnet should removed their stupid ip profile to copy from bt ip profile because it pointless on unlimited package but plusnet say they need the two sides ip profile to match to stop cause any problem to the network. What a loads of rubbish.

BT IP Profile: 15.5Mb
Plusnet IP Profile: 14.4Mb

Throughput: 13.2Mb.

Surely if PN keep a copy of the IP Profile on their system in order to manage the network efficiently and are able to keep their unlimited BB prices low that can not be a bad thing. Can you be sure that it is a "pointless" and a "stupid" thing to do?

Only if and when the IP Profile is slow to update at their end is there an issue. If an end user finds that throughput continues to be slower than normal, perhaps after a period of instability and sync speed returns to the previous level, then they can check on the PN website for the IP Profile and compare it with IP Profile recorded in a BT speed test. If the profiles don't match then it is a simple matter to raise a ticket with, or contact, PN support.

I would expect the Plusnet copy, (Current line speed), to be 15.4Mbps, not 14.4Mbps. If it isn't a typo, a stop of the PPP session for a minute or so, without re-sync'ing, then a PPP restart may kick it up.

Otherwise, give them a ring.

If someone running a heavy download or P2P at the same time as trying to watch HD streaming, using VoIP or gaming how do ensure that the latter three take priority? If it is just left to the BT system surely the downloads and P2P will affect the other activities?

That's nothing to do with IP Profile copying.

No?

If their system doesn't have a copy of the IP Profile how do they know what the capacity of the line is if they apply the quality of service I'm asking about?

Where are you asking about QOS?
Are you also asking about DPI?

perhaps they apply it to a notional 8M or 22M (ADSL2+) or just leave it to BT's BRAS to do whatever the RFC calls for it to do.
