一种改进的P2P文件共享系统研究

Research of an Advanced P2P File Sharing System

在分层的网络结构基础上构建一种改进的文件共享系统模型,针对改进的模型,引入了移动Agent技术并充分结合了蚁群算法的思想,在该模型的基础上具体实现了一个P2P文件共享系统MAPP并对其进行了测试,结果表明,该方法的搜索性能、搜索的准确性和搜索效率等方面与传统的方法相比具有一定的改善和提高。

Based on hybrid network, the paper put forward an improved file-sharing system model. According to the model it introduced a relevant resource search strategy by importing mobile agent and antnest algorithm and optimizing rendezvous. Therefore it implements resource search better. Based on this model, it implemented and tested a P2P file-sharing system which is named MAPP. The result indicates that this system adopts a kind of safeguard search mechanism, comparing with others, it has certain improvement and enhancement on search performance, search accuracy, search efficiency, etc.
