【摘要】 <正> 1.技术背景对等网络(P2P,Peer to Peer)技术是指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信息控制技术。实际上,P2P不是新概念。最早的互联网应用就是实现计算机和计算机之间的对等通信。当代互联网的前身ARPANet就是建立在把计算机作为对等机(peer)而连接起来这一概念之上的,这也是ARPANet最大的技术突破之一。更多还原

【Abstract】 With the explosion of content on the network and quantities of devices connected, it is urgently required todevelop the P2P technologies. Thus, JXTA, a new P2P technology, emerged as the times require. This paper explores P2P and JXTA in particular, and then gives an applied example about it. At last, similarities and differences between JXTA and other typical distributed computing technologies and their application ranges have been deeply investigated.更多还原
