基于自组织算法的发布/订阅系统的研究

Research on Publish /Subscribe System Based on Self-Organizing Algorithm

通过重组织覆盖网络拓扑结构,提出了一种高效的发布/订阅系统。自组织算法把匹配相同事件的事件代理直接相连来实现重组织拓扑结构。结果表明,由于减少了事件发布过程中的事件代理的数量,从而降低了系统开销。

In this paper we propose an efficient publish/subscribe system by reorganizing the overlay network topology. This reorgani-zation is done through a self-organizing algorithm executed by event brokers whose aim is to directly connect,through overlay links,pairs of brokers matching same events. The results show that the number of brokers involved in an event dissemination decreases,thus,reduc-ing its cost.
