摘要:
从理论上和模拟环境上对比特洪流(BitTorrent)中的算法进行研究.首先分析了BitTorrent网络中的P2P文件传输协议,并对BitTorrent客户端和服务器端等功能进行了介绍;然后通过以相邻为1,不相邻为0,利用图的矩阵表示方法建立连接矩阵来模拟抽象数据模型对BitTorrent下载过程中的关键算法既最佳虚拟主机的查找算法进行了研究和分析;进而利用连接矩阵法构建抽象数据模型提出了在大型网络中对网络进行分块的方法来提高BitTorrent的效率,优化了网络通信;最后,搭建测试环境,测试了矩阵分块算法,测试中证明了在一定程度上分块的均匀性可以有效的提高节点文件的下载速度,缩短下载时间,提高BitTorrent的效率.
Abstract:
The algorithm of BitTorrent in theory and the simulation environment was studied. Firstly, the file transfer protocol of P2P in BitTorrent internet was analyzed and the function of the BitTorrent client and server was introduced. Secondly, the key algorithm of BT download process which was about how to find best webhosting service was discussed , which using the connection matrix imitating abstract data model through the method of one indicating adjacent and zero indicating nonadjacent. Thirdly, the largescale network to network partition method was put forward , and the efficiency of BitTorrent was improved and the network communication was optimized. Finally, by setting up test environment and testing block matrix algorithm, it is proved that the block’s uniformity effectively improves download speed of node file, shortens download time and improves the efficiency of BitTorrent.
