Abstract :
A novel Priority-Aware Two Rate Three Color Marker (PATRTCM) is presented in this paper. PATRTCM retains the token buckets scheme of Two Rate Three Color Marker (TRTCM) and its associated parameters, but introduces three marking probabilities, which are calculated in terms of the relative importance of the video packet and the traffic conditions in the network. According to the probabilities, a video packet is marked red, yellow or green. Simulation results show that PATRTCM can improve the end-to-end video quality over DiffServ Networks.
