This paper introduced a dynamic layered multicast scheme,ADLM,to address layer multicast receivers′ heterogeneity in available bandwidth.ADLM uses an optimal layer rate allocation algorithm which can maximally satisfy each receiver′s available bandwidth.Through a novel feedback aggregate algorithm,ADLM dynamically determines the number of layers and the rate of each layer.Simulation results show that ADLM strategy can use network bandwidth more effectively than the RLC strategy,it also solves the problem of network bandwidth heterogeneity.And ADLM is TCP friendly,it can greatly improve the utility performance of layered multicast.
