中文摘要: 从发布/订阅(Pub/Sub)系统的拓扑结构入手,基于结构化P2P,提出分层次的发布/订阅系统拓扑结构,将节点按处理能力分为超节点和普通节点,超节点组织形成超立方体结构,实现整个网络的广播遍历。层次式分布网络不仅具有一般P2P 网络的特性,即能够支持大规模、动态的分布式应用,而且更适合于发布订阅系统中对大量事件的传播的要求。仿真结果表明,基于结构化P2P 的发布订阅系统能显著降低系统负载,提高系统的可扩展性。
Abstract:Starting from the topology of network, based on structural P2P, this paper proposed a hierarchy of publish - subscribe system. The nodes were separated into super nodes and common nodes according to their ability, and those super nodes were organized in Hypercube structure. According to the broadcasting algorithm of the Hypercube, it realized the traverse in the whole network. The result of the simulation indicated that the system load could be well balanced and bandwidth could be saved in this system.
keywords: publish-subscribe system structural P2P Hypercube load
