基于JXTA的P2P即时通信系统设计

课题研究使用JXTA搭建P2P网络,完成即时通信系统。即时通信系统分为发送、中继转发和接收三部分。其中中继转发部分在启动时加入P2P网络,并且在P2P网络中发布提供即时通信服务的通告。发送部分加入P2P网络,通过查找P2P网络通告寻找提供服务的即时通信结点,选择结点形成P2P网络通道。发送端在这个通道基础上建立与接收端的SOCKET连接,将信息传递到接收端。

The P2P Instant Messaging System Based on JXTA Network

The subject is studied and uses JXTA to put up P2P network, to finish the instant messaging system. The instant messag- ing system is divided to three parts of the sender, transfer and receiver. Transfer joins P2P network while starting, and issue the no- tice offering the instant messaging service in P2P network. Sender add to P2P network, through looking for P2P look for transfer that render service by network notice, Choose transfer to form P2P network pass way. The sender set up and connected with SOCKET of the receiver on the basis of this pass way, will transmit information to the receiver.2
