摘　　要：在采用面向服务架构(SOA)实施分布式开发中,为实现对服务资源在效率、可伸缩性和自适应动态演化的支持,通过对企业服务总线(ESB)拓扑模型的分析,引入对基于域内服务注册的统一ESB基础设施的自组织机制(SOM)。通过对SOM的设计,实现了ESB中服务的动态加入和退出机制、服务状态动态变化机制、负载感知的自适应机制和节点的容错机制。在对SOM的仿真与实践中,证实了SOM占用带宽少、信息收敛快、适应性好。To support service resources＇ efficiency, scalability and dynamic adaptability in the distributed developing which adopted method of SOA, by analyzing the topology of ESB, introduced SOM to union ESB infrastructures in which service instances registered in ESB domain. By the self-organizing design, supported many functions, including service dynamics, the load-aware self-adaptation and fault tolerance. In the end, evaluated the performance of SOM through simulations and applications. It demonstrates that SOM has low bandwidth, fast convergence and the ability to recover from emergencies quickly.
