| 摘 要： | 为了减少BitTorrent(BT)产生的大量跨ISP流量且同时保证用户的下载速率,提出了一种基于对等方地理位置的加权tit-for-tat机制(GLW-TFT).首先,根据对等方的地理位置信息将BT群集系统中的对等方分为4类,然后根据ISP收益情况给每一类对等方赋予权重,最后利用加权的下载速率来常规上载对等方集合.基...

| Abstract: | In order to reduce cross-ISP(Internet service provider) traffic caused by BitTorrent(BT) and guarantee the downloading rate of BT users,a weighted tit-for-tat mechanism based on geographical locations of peers called GLW-TFT is put forward.First,peers in the BT swarm are divided into four categories according to their geographical locations.And then,a weight based on the ISPs' income is assigned to each category of peers.Finally,a metric based on weighted downloading rate is proposed to regular unchoke peer... |
