【摘要】：近年来,随着信息技术的飞速发展,融合业务作为下一代网络业务的主要呈现形式,实现了全新的业务开发提供模式。通过BPEL技术,融合业务能够快速整合不同网络下的多种形式的业务,为用户提供全网支持的语音、数据和视频结合的综合服务,实现了业务的快速整合开发。然而,融合业务在高效稳定地对外提供方面存在以下三个问题:其一,融合业务的伙伴链接调用缺乏可靠性保障,无法适应变化频繁的网络环境;其二,基于BPEL的融合业务执行引擎的并发能力有限,需要扩展以满足更繁重的业务请求;其三,融合业务的部署、管理、监控和告警等需求缺乏统一的管控平台,其管理维护操作不够方便。本文提出了一个支持适变业务的分布式业务管控系统。通过对该系统进行需求分析,提出了服务快速适变、业务分布式执行和多方位管控三个方面的功能及非功能需求。基于这样的需要,该系统在开源业务执行引擎上进行扩展,提出了基于接口特征簇的服务适变算法,用于解决业务运行中进行备选服务发现耗时太长的问题,实现服务快速适变;其次将单一的引擎转化为分布式集群架构,提高了业务的并发处理和扩展能力;实现了集业务部署、监控、管理、告警于一身的Web管控平台,对整个执行环境进行管理,达到了多方位管控的目的。通过对背景的阐述和需求分析,本文设计了支持适变业务的分布式业务管控系统的架构,对主要的功能模块进行详细设计,并详细阐述了基于接口特征簇的服务适变算法,用于解决融合业务服务适变这一关键问题。最后,通过对系统的适变能力、并发能力和管控能力三个方面的实验测试,验证了该系统设计的正确性和合理性。最后,对整篇论文进行总结和分析,整理了不足之处,并做出下一步的工作展望。
[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.
