基于组播和P2P的文件分发管理模块的设计与实现

本文对CNGI研究课题"组播与P2P相结合的文件分发系统"进行了简要介绍.通过对该系统文件管理模块的总体设计和详细设计,实现了基于IPv6组播与P2P技术的结合.该系统借助JxTA平台实现P2P的基本功能:节点搜索、节点资源搜索、节点间的通讯和文件的统一管理等,实现了尽量利用可靠的组播并利用P2P实现跨组播域的信息传输.最后通过对管理模块在不同环境下的测试数据进行分析,表明该设计思想的有效性.

Design and Implemeotation of File Distribution Management Module Based on Multicast and P2P

This paper introduces a CNGI research project A File Distributing System by The Cooperation of IP Multicast and P2P. Through careful design of the file management module of the system,a combined function of IPv6 multicast and P2P fulfilled can be realized. By using the JXTA P2P platform,the system implements the basic functions of node searching,node resource searching,communication among nodes and unified file management. The system uses the multicast function if it is available,then P2P function is used t...
