摘　　要：为解决实验教学中出现的局域网内大文件快速分发问题,提出了一种基于P2P技术的传输方案。分析了P2P的工作原理、网络分类、网络特点以及BitTorrent工作过程等,设计了一个典型实验网络拓扑,并搭建了真实网络进行了验证。利用MYBT软件搭建了P2P服务器,在种子节点和下载节点数量变化情况下,对约4GB的文件进行分发,统计了平均下载时间。实验结果表明,相对于FTP等集中式传输而言,基于P2P技术的文件共享系统节省了大量时间,很好地实现了局域网内大文件的快速分发。A transmission solution based on peer-to-peer（P2P）technology is proposed to use the large file fast distribution via LAN in experimental teaching.This article studies the principles,network classification and network characteristics of P2 Ptechnology and working process of BitTorrent.A typical experimental network was designed and verified in a real network environment.A P2 Pserver was built by MYBT software in the experiment.The average download time was counted for a 4GB file with difference of seed nodes and download nodes.The experimental results show that,compared with the centralized transmission mode such as FTP,the file sharing system based on P2 Ptechnology can save a lot of time and ensure the large file fast distribution via LAN.
