Hello, As it is well know that CBQ is the class based queue. But i am confused on the word "class" now, especially it is used in Diffserv. IMO, different classes should mean that there are different kinds of traffics, so the class should be difined by the parameters (such as bandwidth, priority..) the traffic wanted. That is, using cbq we can define different kinds of traffics which need different bandwidth at the gateway, am i right?? Then, in diffserv the traffic is identified by the DSCP, right? From Floyd's paper Link-sharing and Resource Management Models for Packet Networks, we can see if there are two classes of traffic such as class A and class B, and each of them has traffics video and ftp, then how the two different FTP are identified in diffserv, by their DSCP? IMO, at first, according to the bandwidth the traffic needed, the traffic is classified into class A or class B, then at each class the traffic is identified by their DSCP. Eagerly waiting for your reply!
