Maybe this is also the source of the misunderstanding: I referred to Linux classes, which are just generic containers of packets. 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.
