BT网络性能的研究与改进
Research and Improvement on the Network Performance of BitTorrent
近年来，P2P网络逐渐成为新一代互联网技术研究的热门话题，作为P2P网络的典型代表BT下载方式出现之后，很快就被下载迷们用来交流最新的电影大片或软件，如今已经得到广泛的推广。本文在介绍P2P技术以及BT的工作原理和下载流程的基础上提出了BT这种多源文件下载机制下的位置知晓性问题，并将从位置知晓性入手，通过加入IP节点集群方案，使之能够在节点和文件块的搜索上能有所改进，从而减小带宽消耗。在中国目前宽带网络支撑力严重不足的情况下，这种方案非常具有现实意义。
Peer-to-peer network is becoming the hot topic about the new Internet technologies. As soon as BitTorrent ,the representative of P2P networks ,emerges as a download software, many BT fans use it to share the latest movies and softwares. This paper provides an introduction of P2P networks and the concept of BitTorrent, especially the downloading mechanism. On the basis of this,we have put forward an improved scheme focusing on the Location-Awareness. The design we have suggest in this article is to increase the search efficiency of peers and blocks mainly by adding a node trunking project to the downloading mechanism. So the bandwidth consumed by BT will be reduced.It is such a significative project especially for China now facing the serious problem of network capability.
