Peer-to-Peer对等网络可信性的分析和比较

Analysis and comparison of dependability of P2P networks

对等网络(peer-to-peer,P2P)技术是目前新一代网络技术研究的活跃领域。随着基于对等网的应用越来越广泛,对P2P网络的可信性的研究具有现实意义。首先介绍了P2P网络的基本特征以及P2P网络的分类,提出了P2P网络可靠性评估方法,并从可靠性、可扩展性、适应性及完整性等几方面对各类不同类型的P2P网络的可信性进行了分析和比较,最后展望了P2P未来的发展方向。

Peer-to-peer （P2P） network technology is a currently emerging technology in the network research domain. With application based on peer-to-peer network the more and more widely, the research on dependability of P2P is real significance. The P2P＇s charactertics and classes are described, and a method is presented to evaluate peer-to-peer network＇s dependability. And then dependability of P2P networks is analyzed and compared, at the end, the peer-to-peer development prospect in the future is forecasted.
