【摘要】 随着移动通信网络的迅速发展,在移动网络中提供P2P服务,特别是BitTorrent(BT)文件共享系统的需求日益突出。该文从BT协议的特点及3G网络的实际情况出发,分析扩展eDunkey体系、移动代理服务器等方式的不足,提出一种基于IMS的BT文件分布系统架构,研究了系统的工作机制和各组成部分的功能,解决了网络结构复杂、成本高、不易推广等问题。更多还原

【Abstract】 With the fast development of the mobile communication networks,the need of providing P2P(Peer-to-Peer) services,especially the BitTorrent(BT) file-sharing system in mobile networks is growing.According to the features and actual situation of BT protocols and the 3G networks,a BT file-sharing system architecture based on IMS(IP Multimedia Subsystem) is presented,after analyzing the disadvantages of the extended eDunkey,mobile proxy,and other existing manners,mechanisms of the system and the function of each part are described.The problems of complicated network structure,high cost and hard to promote are solved.更多还原
