摘要
文章介绍了超节点结构P2P覆盖网拓扑不匹配问题,分析了当前在研究解决这一问题时面临的不足,在此基础上提出一种在经典拓扑(Topology)和地理(Geography)位置相结合的基础上形成覆盖网的方法MBTG(Method Based on Topology and Geography)。实验表明该方法解决了超节点结构P2P覆盖网中物理结构和逻辑结构拓扑不匹配问题,保证了物理网络与覆盖网的一致,从而节省了文件搜索时间,提高了查询成功率等。
The paper introduces the topology mismatching problem of the P2P overlay based on super-node, analyzes the deficiency of current researches about this problem. The paper presents a method based on the cooperating of typical topology and geography (MBTG). The simulation shows that the MBTG is effective in solving the topology mismatching between the physical structure and logical structure. It guarantees the consistency between physical networks and overlays. So it saves the search time of files and improves the search success rate and so on.
