Application Layer Multicast Algorithm Based on Peer Performance Evaluation
Lei Lv · Jisuanji gongcheng · 2009
This paper proposes a new Application Layer Multicast(ALM) algorithm based on the peer performance evaluation, an ALM based on Peer Performance Estimate(PPE) which constructs and maintains the ALM tree. PPE organizes the multicast tree mainly by the peers transmission ability and incorporates other related information. 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. Analysis and simulations show that PPE can efficiently improve the performance of ALM on large scale peer conditions.
