A New Adaptive Cumulative Layered Multicast Scheme

In this paper, we introduced an adaptive cumulative layered multicast scheme, ACLM, to address multicast receivers' heterogeneity in available bandwidth. ACLM uses an optimal layer rate allocation algorithm which can maximally satisfy each receiver's available bandwidth. Through a novel feedback aggregate algorithm, ACLM dynamically determines the number of layers and the rate of each layer. Simulation results show that ACLM is adaptive and TCP-friendly. Meanwhile it can optimize overall throughput.
