是一种网络新技术，依赖网络中参与者的计算能力和带宽，而不是把依赖都聚集在较少的几台服务器上。P2P网络通常用于通过Ad Hoc连接来连接节点。这类网络可以用于多种用途，各种文件共享软件已经得到了广泛的使用。P2P技术也被使用在类似VoIP等实时媒体业务的数据通信中。(It is a new network technology that relies on the computing power and bandwidth of the participants in the network, instead of aggregated dependencies on a few servers. P2P networks are usually used to connect nodes through Ad Hoc connections. This kind of network can be used for a variety of uses, and all kinds of file sharing software have been widely used. P2P technology is also used in data communications such as VoIP and other real-time media services.)
