对等网络计算平台JXTA的研究
摘要
日新月异的计算机科学为互联网的发展带来了无穷的活力。随着微电子技术、光电子技术的发展，掌上电脑(PDA)、移动电话(Mobile Phone)，各种信息家电不断问世，同时它们也需要得到来自互联网的现有丰富服务资源。这些设备和传统的服务器、工作站、个人电脑组成了一个庞大的、复杂的网络，所有这些设备又可能提供自己的服务。但是怎样才能管理这个复杂网络和其中的各种设备和服务?怎样实现设备之间的相互通信?对等网络计算可以解决这些问题，从而进一步拓展互联网的空间。
论文首先阐述当前互联网服务所普遍采用的客户/服务器模式、对等网络计算的历史与发展现状；其次详细分析新的对等网络计算平台——JXTA，包括它的架构和协议；最后给出开发实例——一个建立在JXTA平台之上的对等网络游戏框架，并对JXTA进行技术总结和展望。
Computer science changing with each passing day has motivated the development of Internet. With the rapid development of micro-electronic and photoelectron technologies, PDA, Mobile Phone, Information Appliances have been produced, and they all need the rich existing service resources. These devices, together with traditional server, station, personal computer, compose a huge and complex network, and these all devices can also provide services themselves. But how do you manage the complexity of a network and all kinds of devices and services? How to make these devices communicate each other? Peer-to-peer networking(p2p) can solve these problems and extend Internet.
First, the paper explains client/server model, the most popular model used by most Internet services, and the history, status quo of peer-to-peer networking. Secondly, it analyses a new p2p platform, JXTA, including its frame and protocol. Finally, the paper provides a practical instance - a p2p network game framework built upon JXTA, and pictures the prospect of JXTA technology.
