无结构P2P网络搜索方法及其改进

Search Methods and Its Improvements for Unstructured P2P Networks

对等(P2P)计算是未来网络中的关键技术,对等网络是实现下一代互联网的重要组成部分。如何高效地搜索P2P网络上的资源是P2P网络实现的最为关键的问题。在讲述对等网络的基本搜索方法的基础上,分析了许多改进的搜索方法,包括基于转发的改进方法、基于缓存的改进方法和基于覆盖网拓扑优化的改进方法。

Peer-to-Peer computing will be a key technology in future networks, P2P networks will be an important part of the next generation Internet. How to search the resources in the P2P networks efficiently is the key problem when the P2P networks are developed. After introducing the basic search methods, this paper presents many improved search approaches. These include： forwarding-based approaches, cache-based approaches and overlay topology optimization.
