摘要
以BitTorrent为例,分析了目前流行的P2P系统的工作原理及其存在的问题,介绍了在P2P系统运用网络编码技术来解决这些问题的方法,说明使用网络编码技术可提高文件下载速率,增强系统的鲁棒性,可很好地解决P2P系统中“种子”退出造成的文件下载不完的问题。
In this paper,the operating principle and weakness of the popular P2P software system like BitTorrent are analyzed. A method to overcome the weakness with network coding is proposed. File download time is improved with network coding. Moreover,network coding can improve the robustness of the system and is able to smoothly handle extreme situations in which the server and nodes quit the system.
