Adaptive layered multicast congestion control mechanism

More and more attentions have been paid to layered multicast for Internet intrinsic heterogeneity, but little work had been done on "adaptive layering" multicast. We proposed and evaluated a congestion control mechanism for adaptive layered multicast (ALM). Through a novel feedback aggregating algorithm, ALM dynamically determines the number of layers and the rate of each layer. Simulation results show that ALM is adaptive and TCP friendly.
