Why is a PN profile necessary?

The topic about PN Profiles not necessarily updating properly set me to wondering why Plusnet needs to apply its own profile.  Won't the fact of the BT IP Profile do all that is necessary?  AFAIK other ISPs don't apply their own profile; or do they just keep quiet about it?

We match the IP profile against BT Wholesale so we can apply per user QoS to your line. This allows us to prioritise your high priority traffic above low priority traffic. If we didn't have this profile then we wouldn't know the maximum rate your line could support, therefore if we allowed more traffic through on our side of the network than your line could support you would see random packet loss at the BTW BRAS and this could be any type of traffic (VoIP, P2P etc).
So by applying the profile on our side we can control what traffic is affected first, therefore allowing high priority traffic to be unaffected and only the lowest priority traffic to be affected.

Re: Why is a PN profile necessary?

I'm not entirely convinced by that explanation.  For one thing the delay in tracking changes in  your BT IP profile must mean that if it goes down you will see random packet loss whereas if it goes up you just see an unnecessary speed restriction - until Plusnet catches up.  I just wonder if the whole system isn't more trouble than it's worth? And I repeat: what do other ISPs do?

Re: Why is a PN profile necessary?

Thanks Oldjim, I missed that one.  But I still cannot see that the current system is not more trouble than it's worth.  It just adds a whole layer of extra complexity for what seesm to be rather dubious benefits.
Plusnet, how about running a trial of a no/fixed PN Profile?

PN must be moving in this direction as with all fibre accounts the PN profile is fixed, so I guess they don't see it as so much of a problem when there are such vast amounts of bandwidth available?

We do have profiles for Fibre but not for 80/20 (yet)

Re: Why is a PN profile necessary?

So if profiles are not always used by Plusnet, does that mean the argument put forward in their favour is outdated or hokum?

Re: Why is a PN profile necessary?

The only reason we don't have them for 80/20 in the incremental steps is because it's not a full product, it's currently still a trial.

Re: Why is a PN profile necessary?

Sorry Oldjim, still none the wiser.
As the old saying goes: "If it's broke, is it economically repairable?".  It's clear that Plusnet's system for tracking your BT IP profile is a bit iffy at the best of times and responds much more slowly than intended at the worst of times.  I presume somebody is putting some effort into fixing this but I wonder if this is really worthwhile?  Or has the problem just been brushed under the carpet?

Re: Why is a PN profile necessary?

As you might have read on the other thread that Jim linked you to, us matching BT's profile is pivotal to our traffic management system so they are crucial and not outdated at all. As always we're taking your feedback on board about this, thanks for raising your concerns about this and I am sorry if this causes problems for you.

What I cannot get my head around is how you (Plusnet) can cope with the 24 hour delay that is normal and the 72 hour delay that seems quite common.  If your system can cope with mismatched profiles then it can't be pivotal.
