Abstract: This paper discusses some concepts on Service-oriented Architecture(SOA), insists that SOA is a developing methodology rather than a specific technology. Moreover, the paper designs the service cooperative mechanism based on SOA. Many functions are supported, including service dynamics, the load-aware self-adaptation and fault tolerance. According to simulations and applications, this mechanism has low bandwidth, fast convergence and the ability to recover from emergencies quickly.

Key words: Service-oriented Architecture(SOA), service resources, cooperative organized mechanism, bus, distributed application

摘要： 面向服务架构(SOA)是一种架构模型和开发概念，对总线的资源组织方式进行设计。通过总线资源的协同组织机制，实现总线上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。在仿真与开发中，证实了该机制效率高、收敛快、适应性好，适用于大型分布式应用集成系统。
