P2P流媒体索引服务器的快速源节点选择算法

软件简介：

在P2P系统中,源节点的选择方法对网络的性能有很大影响,已有的拓扑相关源节点选择法着眼于改进在请求节点执行的算法,忽视了服务端的源节点选择质量,可能会导致请求节点根本无法选出满意的服务节点。本文提出了适用于执行查询请求的服务端的源节点选择算法,可以使节点间平均延迟大约降低80%,同时也具有可接受的执行速度。本算法最大的特点是简单、有效、高效。

In P2P networks, the algorithm of selecting source peers has a significant influence on the performance of the system. Existing methods on topology-aware peer selection focus on improving the algorithms performed in the requesting peers, these methods ignore the quality of source peer selection in server side, and this might cause the requesting peers to be unable to pick out satisfied servant peers. We propose a source peer selection algorithm suitable for the server side which executes query requests. Whi...
