[Abstract]:In recent years, with the rapid development of information technology, integration services as the main presentation of the next generation of network services, the realization of a brand-new business development and supply mode. Through BPEL technology, the converged service can quickly integrate various forms of services under different networks, provide users with integrated services supported by the whole network of voice, data and video, and realize the rapid integration and development of services. However, there are three problems in the efficient and stable external supply of converged service: first, the partner link call of converged service lacks reliability guarantee and can not adapt to the frequently changing network environment; Secondly, the concurrency ability of the converged service execution engine based on BPEL is limited, so it needs to be extended to meet the more onerous business requests. Third, the integration of business deployment, management, monitoring and alarm needs lack of a unified management and control platform, its management and maintenance operations are not convenient. In this paper, a distributed business management and control system supporting variable services is proposed. By analyzing the requirements of the system, the functional and non-functional requirements of service rapid adaptation, business distributed execution and multi-directional control are proposed. Based on this requirement, the system is extended on the open source business execution engine, and a service adaptation algorithm based on interface feature cluster is proposed to solve the problem of too long time for alternative service discovery in business operation. Implementation of rapid service adaptation; Secondly, the single engine is transformed into a distributed cluster architecture, which improves the concurrent processing and expansion ability of business. The Web management platform, which integrates business deployment, monitoring, management and alarm, is implemented to manage the whole execution environment and achieve the goal of multi-directional control. Based on the analysis of background and requirements, this paper designs the architecture of distributed business management and control system to support adaptive services, designs the main functional modules in detail, and expounds the service adaptation algorithm based on interface feature cluster in detail. It is used to solve the key problem of converged business service adaptation. Finally, the correctness and rationality of the system design are verified by the experiments on the adaptability, concurrency and control ability of the system. Finally, the whole paper is summarized and analyzed, and the shortcomings are sorted out, and the future work is prospected.
