Packets can = be redirected into Linux classes by defining filters. In other words, by defining a pair (desired filter, Linux class) one can = redirect the desired packets into the class. I used this mechanism to put each UDP flow, as well as the video stream, = in a separate Linux class, and then perform per-flow scheduling among = these flows. I think that, in Linux, using these classes is the only way to perform = per-flow queueing with differentiated weights.
