plusnet shape but they also do priority class's for different types of traffic. gold silver bronze etc.

so they will throttle specific things down such as p2p and as you say very severely. Then on top of that if their pipes are hitting saturation point then stuff in their bronze class will be further throttled by deliberatly dropping packets to maintain the higher class's. Things like VOIP are in their platinum class I think. Web browsing is in gold class, and if you on their PAYG product everything is gold. So plusnet's is more advanced.

VM appear to have no system's in place that react to saturation and is a simple protocol shaping mechanism. My thoughts based on what I read here and elsewhere and what I know of plusnet's system (as they quite open about it). Plusnet even admit they shape unidentified traffic.

They even do things like throttle gaming traffic to 2mbit but put it in a high priority class. This I guess means if they accidently mark traffic as gaming or someone fakes it, they will still be throttled but gamers wont find their packets been dropped as they in a high priority class.
