Whatever. No-one's actually trying to do "some packets are more equal than others" here in Europe, except for the mobile people with IMS and such. BT just transferred its access network into a new division with a specific remit to provide open access to all ISPs and alt- tels who want it.
I'm sorry if I made the impression that it is already happening. Now it's a game on the political arena, and it's important to support the RIR-communities' efforts to provide balanced information to decision-makers.
My guess would be that basically everybody doing triple play will prioritize the IPTV and VoIP packets in their network including the access. Considering that streaming UDP IPTV requires very very low packet loss, much better than Best Effort, this is needed to provide a good quality service.
If you do LLQ you want to make sure you can control what goes into that class, that can be done several ways, including disallowing anything you don't know about (transit/ix) to go there.
This is preferential treatment for some packets and it makes perfect technological sense.
Preferential treatment of value-added services in the providers own network is just fine. It's down-prioritizing competing services that may become a problem. Like blocking all VoIP traffic not using the providers' own "gateway-service". //per -- Per Heldal http://heldal.eml.cc/
