可扩展发布/订阅中间件技术研究

Research on Extensible Publish/Subscribe Middleware

发布/订阅系统技术具有异步松散耦合和多对多通信的特点,适应了目前动态多变的大规模分布式计算环境的需求,有着广阔的应用前景。由于应用需求的日益增长,发布/订阅中间件面临特殊化与通用化的两难选择。文中采用动态体系结构设计方法,以配置管理和元服务管理的机制,设计和实现了可配置和可扩展的发布/订阅中间件系统,能够有效地解决基于特定应用领域需求配置发布/订阅服务系统的问题。

The publish/subscribe system is adapted to the dynamic large-scale distributed computing environment well and will be used widely due to its asynchronous ,many-to-many and loosely-coupled communication properties. With their increasing popularization ,developers face the dilemma to choose application-specific or general purpose publish/subscribe middleware. With the method of dynamic architecture design, this article designs and realizes a customizable and extensible architecture for publish/subscribe middleware,which is based on configuration management and meta-service mechanisms. Such design efficiently solves the problems of configuring publish/subscribe service system based on any specific application domains.
