Pan Shu-qin · Jisuanji gongcheng · 2010
In view of node heterogeneity and large transmission delay problems of current application layer multicast,an application layer multicast algorithm is proposed based on topology architecture and peer performance.Network will be layered and clustered according to the topology-aware approach.It can fully consider node heterogeneity when constructing the multicast tree.The algorithm makes the high performance peer close to the media source and the low performance one close to the leaf,which improves the efficiency of the multicast tree and decreases the delay of peer-to-peer,link stress,link stretch and control overhead.Experimental results show that algorithm can efficiently improve the multicast tree performance on large scale peer conditions.
