We present in this paper a simulation-based comparison of two single-rate multicast congestion control schemes (TFMCC and PGMCC) against our proposed Adaptive Smooth Multicast Protocol (ASMP). ASMP consists of a single-rate multicast congestion control, which takes advantage of RTCP Sender (SR) and Receiver Reports (RR). The innovation in ASMP lays in the “smooth” transmission rate, which is TCP-friendly and prevent oscillations. The smooth behavior is naturally well suited to multimedia applications as high oscillations of the sending rate may create distortions of Audio-Video (AV) encoders and decoders. Simulation results, which are conducted with the network simulator ns2 software, showed that ASMP can be regarded as a serious competitor of TFMCC and PGMCC. In many cases, ASMP outperforms TFMCC in terms of TCP-friendliness and smooth transmission rates, while PGMCC presents lower scalability than ASMP.
