基于内容的Pub/Sub系统中分发器网络自重构的研究

Self-reconfiguration of Dispatcher Network for Content-based Publish/Subscribe System

提出了提高基于内容的Pub/Sub系统健壮性和交互效率的系统自重构方法。该方法包括系统的恢复策略和系统的自组织策略。系统的恢复策略,预防了节点的意外崩溃造成的系统瘫痪;系统自组织策略,有效地降低了系统的事件交互成本,提高了基于内容的Pub/Sub系统的效率。自重构方法在基于内容的Pub/Sub系统SOES中得到了体现。

This article presents a strategy for the network to be fauh-tolerant, which enables the system to quickly recover from crash of underlying dispatchers. Moreover, it brings forth a novel solution based on “ Dispatcher Association” for the network to self-organize to boost dispatching efficiency, SOES is the system under development to testify such a notion that underlying network for content-based pub/sub system support self-reconfiguration.
