| Under the environment of network convergence, SEE(Service Execution Envrionment) is not only to provide value-added Application execution environment, but also provide diversified, multimedia integrated and personalized synthetic service, and can provide open-ended, wide-area distributed coordinative and integrative ability of collaborative application operation. So this paper propose a kind of coordinative services based service execution environment(CSB-SEE).Firstly this paper introduces the background of enterprise service bus(ESB) based New Generation Operations Systems and Software (NGOSS), and then introduces and analyze the important technology of building the system:Agent, ICE middleware, interceptors and etc.Then determines the main two parts of the the system:Single Point Execution and Area Coordination. Through using the method of Attribute-Driven Design, analyses the function and quality attributes of the system, then determines the whole software architecture.For Single Point Execution, uses the message business, and makes the communication between applications and plugins became flexible and effective. And applies Interceptors into plugin, which will make the plugin can not only provide extra abilities, but also can get deep informations of the applications, network environment and the platform, and these informations can be shared through the coordinative service bus.For Area Coordination, designs the architecture, implementation and the mechanism of CSB using the technology of ESB, Agent and ICE, then makes CSB and SEE combinded together. And CSB divides the problem of distributed collaboration into some areas and parts, then through the collaboration of regional and classifical service bus nodes and the service execution nodes with agent, last achieves fast combination of services.Finally, from the aspect of application management, the plugin loading instantiation, the cooperation of plug-ins and applications, initialization of CSB, the combination services through collaboration of CSB and service execution nodes, this paper demonstrates each major functions of the running mechanism of the framework. Finally introduced testing methods and method. At the end of the paper is summarise, and further research work introduction. |
