[Qin]: There are two different levels for service differential
 1evel 1: How to separate HTTP streaming service from High Speed Internet Service(HSI) Since HTTP streaming service and HSI share the same channel and HTTP Streaming service may require more bandwidth or other resource to support high quality content delivery. If the serve can do some mark in the HTTP header and there is some smart cache with intelligence to understand this mark situated between the server and client, the smart cache can treat HTTP streaming traffic in the different way as web traffic.

 level2:   How to treat different HTTP streaming traffic with different priorities.
 This is more precise granularity of service differential. If there is way to do this, HD HTTP streaming can be treated in the different way as SD HTTP Streaming. 
 Smart cache is one way to do this.

 As for these two levels of service differential, I agree there is other ways to deal with it, I just think it is quite interesting issue to me, when I dig this problem out
