用IP组播实现同位体发现机制

Peer to Peer（P2P域对等网络），是一种在不同电脑用户之间不经过中继设备而直接完成数据交换或服务交换的技术，Peer to Peer技术将引导网络计算模式从集中式向分布式转移，组播是一种允许一个或多个发送者（组播源）发送单一的数据包到多个接收者（一次的，同时的）的网络技术，文章探讨了IP组播技术的Peer to Peer网络中应用的可能性。

A Peer Discovery Implementation by IP Multicast

Peer to Peer is the technology that gives customers the chance which they can grasp to share files or exchange data directly. Peer to peer leads the trend from center computing to distribution computing .IP multicast is also a useful technology in case of NetMeeting or video cast, thanks to its natural character which allows one source send the same packet to multi-receiver. This paper wants to seek the combination possibility of these two technologies.
