新一代基于P2P的图书馆信息系统

Towards Next Generation P2P Based Library Information System

目前的图书馆信息系统是基于 C/S架构的 ,在因特网分布式网络环境下 C/S结构系统的不足越来越突出。 P2 P系统是传统 C/S系统一个很好的替代 ,它的每个节点既可作为客户又作为服务器并以允许访问其计算资源作为其参与的代价 ,象 Napster和 Gnutella系统已证明了其实用性。本文在分析 P2 P网络的现状和特点的基础上 ,给出了将其应用在图书馆信息系统中几种形式。

The current library information systems are based on Client/Server architecture, which are becoming more and more disadvantage under the distributed environment of Internet. P2P is a good alternative of C/S systems, in which each node is working as both clients and servers. The good examples are Napster and Gnutella systems which are proved to be practicable. In the paper based on the analysis of the current state and the features of P2P network, the author present several kinds of P2P-based applications in library information systems.
