Wei Zhou · Jisuanji gongcheng · 2009
According to the characteristics and special requirements of constructing Application Level Multicast(ALM)tree,this paper proposes a new ALM algorithm based on available bandwidth measurement.Depending on the relation between the input data rate and the one-way delay,it uses multicast data as the probing source,and calculates the available bandwidth.The method helps the application reduce probing cost and influence on the network.Simulation demonstrates the effectiveness of the algorithm in terms of throughput and average link stress.
