Description

基于P2P网络的数据处理方法、装置及系统

技术领域
本发明实施例涉及信息技术领域，尤其涉及一种基于P2P网络的数据处理方法、装置及系统。
背景技术
近些年来，随着信息技术的不断发展，P2P技术得到了广泛的应用，P2P是英文Peer-to-Peer(对等)的简称，又被称为“点对点”。“对等”技术是一种新兴的网络技术，主要依赖于网络中参与者的计算能力和带宽，而并非把所有依赖都聚集在成本较为昂贵的服务器上去。P2P亦是point-to-point(点对点)的简称。也就是说它自己的下载的同时，也要上载给网络上的其他节点。参与P2P网路的用户越多，相应的上载者就越多，上载者数量越多，P2P终端到服务器上取数据的机会也就越小，所以P2P的存在不但使服务器压力大大减少，更达到了人数越多速度就越快的效果。
目前，在P2P网络中节点与节点之间进行数据交互时，有时其中的一个P2P节点在获取得到另外一个P2P节点的节点信息之后，会与其进行恶意链接，并向其发送虚假数据；或者由于网络延迟等原因，会导致数据交互的不完整，进而会造成一方节点误认为另一方节点发送的是虚假数据。无论以上哪种方式都会占用P2P节点连接资源，进而会影响P2P网络的分享效率。
