Mutil-Service Execution Environment Subsystem Design And Implementation

In recent years, under the environment of convergence network, MSEE(Mutil-Service Execution Environment) need to provide execution environment for variety of value-added services. MSEE need to provide access to various resources such as the storage access for the the date of services and the date of the users. MSEE also need to support the rapid development of services and the rapid deployment of the services. This paper focus on the Mutil-service execution environment subsystem design and implementation is base on the new generation environment of services running, controlling and collaborative under the convergence network.The paper first introduce the background of the MSEE and the related technologies which will used in the implementation of the MSEE.Second,the paper introduce the position of the MSEE in the SRC(Service Runtime Coordinative Execution) and descide the major function of the MSEE as flows, services parsed, services trigger, the services life cycle management, support for the multi-instance and multi-service running, providing services development interface and provide the support for SIP protocol. After the analysis of the functions, the paper presents the architecture of the MSEE.Third, the paper introduce the details of the modules about the design and implementation according to the architecture of the MSEE. The paper introduces the details of the modules in the order of resource module,service triggered module, service container module, execution layer and the interface for services development. The paper provide the algorithm description for the service trigger and the rollback of the conflicted services. The paper provides a detailed interactive process to describe the relationship between the modules.After completing a prototype, I design 56 test cases for the prototype to test the function. By constantly testing and debugging, the prototype finally pass all the test cases, in line with the functional requirements presented in the third chapter's.The last part is the summary of this paper and the future work of MSEE.
