Some question

Hi,everyone:
	I am a Master student and my thesis is about the admission control
in
Diffserv IP network, I have one question, anyone can help me?

Four service class defined in UMTS will be used in diffserv.
(Conversational, 
Streaming, Interactive and Background). Conversation will be used as EF,
Interactive
will be AF and Background is best effort. The problem is Streaming, if I
treat it as AF, 
because if I use Priority Queue for EF and WFQ for AF in scheduler, the
delay of Streaming
is hard to control in WFQ; if I put Streaming in the lower priority than
Conversation in EF,
it seems it doesn't conform to the standard of EF in RFC.

Anyone can give some advice, thanks!

Xiao
