P2P网中基于IP组播的发现机制研究

对等网络技术是近年来计算机网络技术的一个热点,而对等技术中的一个热点技术就是如何找到节点的发现机制问题。介绍了P2P技术及其发现机制和IP组播的原理,利用IP组播技术来解决P2P中对等体的发现问题。文中分析并建立了一个IP组播发现模型,在此基础上,结合SUN公司为P2P分布式计算提供的通用统一、可互操作的平台JXTA技术,实现了IP组播技术在P2P网络对等点发现机制中的应用,有效地解决了单点发送多点接收、多点发送多点接收的问题。

Discovery Implementation by IP Multicast in Peer to Peer Network

Peer to Peer network has become new focus of the computer network technology in recent years.Discovery Implementation is one of critical technology in Peer to Peer network.This paper introduces the P2P technology and IP multicast technology,then analyzes and proposes an IP multicast discovery model.On the basis of this,with the use of JXTA project,the application of IP multicast technology in Peer to Peer network discovery implementation is realized and the problem of information transmission from single-peer to multi-peer or multi-peer to multi-peer is effectively solved.
