Peer-to-Peer网络中文件查询的研究

With the development of P2P network, the search problem is coming into been one of the most critical problems in distributed systems. The efficieney of search is the key of the whole P2P network. In this paper, the present situation of P2P network is described. The solutions of search problem in unstructured, structured and loosely structured P2P systems are provided. After analyzing and comparing, we propose shortcomings of the present search and give some suggestions for the future research on P2P systems.
