摘要: 为合理引导对等网络(P2P)的流量,减少关键位置的带宽占用,该文以常用P2P软件BitTorrent(BT)为例,提出一种基于片段融合度的peer选择算法,使得在BT下载效率降低很少的同时,减少了BT流量。通过建模与分析,证明该算法可以大大减少P2P的网间流量。

关键词: 对等网络, BitTorrent软件, peer选择, 下载带宽

Abstract: In order to lead the Peer to Peer(P2P) traffic and reduce bandwidth occupancy at key location, this paper brings forward a peer selection algorithm based on file piece merging degree using BitTorrent(BT) as an example which is a P2P software used by large-scale people. Applying the algorithm, BT traffic can be leaded and optimized. P2P traffic between networks is reduced heavily, which is testified by modeling and analyzing the peer selection algorithm based on piece inosculation degree.

Key words: Peer to Peer(P2P), BitTorrent, peer selection, downloading bandwidth
