摘　　要：从网络拓扑结构着手,提出基于超立方体拓扑结构的发布订阅系统,并在此基础上设计对应的路由算法。基于超立方体拓扑结构网络不仅仅具有一般结构化P2P网络的特性,即能够支持大规模、动态的分布式应用,而且由于自身结构的特点使其更适合于发布订阅系统中对大量事件传播的要求。仿真结果表明,超立方体结构的引入能显著降低系统负载,节省带宽。Starting from the topology of network, this paper proposed a kind of publish-subscribe system based on hypercube with its related routing algorithm, The hypercube-based topology shares the merits of general structured peer-to-peer network, which can be applied dynamically in large scale. Moreover, due to its own characteristics, the needs of propagating a large number of events can be met. The result of simulation indicates that the system load can be well balanced and bandwidth can be saved, when hypercube-based network is introduced.
