基于NGOSS体系结构的服务等级协定管理系统
|
摘要
电信市场的开放使得多种服务提供商得以进入市场参与竞争,在这种竞争的环境中,争取更多的客户成为服务提供商要解决的首要问题。服务等级协议(Service Level Agreement简称SLA)就是这个竞争环境的产物。
本文首先阐述了SLA系统的相关规范和理论。其中包括下一代运营系统和软件(Next Generation Operations Systems and Software,简称NGOSS)规范的介绍、企业应用集成(Enterprise Application Integration,简称EAI)与SLA系统关系的分析,SLA理论研究。在SLA理论研究中给出了系统的管理数据模型。然后根据这些规范和理论设计出自己的SLA系统,其中对系统的软件体系结构和运行体系结构进行了研究,同时给出了系统的网络拓扑结构和技术路线。SLA系统中的一个关键问题就是服务质量(Quality of Service,简称QoS)参数的计算。针对QoS参数计算这个问题,我提出了一个具有普遍性和灵活性的算法。我将算法的设计同数据库的设计相结合,将计算公式进行分解,并把信息存入数据库。最后对该系统的优点和缺点方面作了总结。
The telecommunication market is being opened up, enabling a variety of service providers to enter and compete for customers. Under this competitive environment, drawing more customers has been the first problem to be resolved to win in the competition. Service Level Agreement (SLA) is a competitive outcome.In the first, this paper introduces the interrelated criterions and the theories of SLA, including of introduction of Next Generation Operations Systems and Software (NGOSS), analyse of connection of Enterprise Application Integration (EAI) and SLA, studying of the theory of SLA. In that studying, I bring the models of the managed data. In the second, depending on the criterions and the theories, design my own SLA management system. In the system, I analyse the software construction of the system and running construction of the system. At the same time, I bring the network configuration and technical route. It is import problem about Quality of Service (QoS) parameter calculating in SLA. Aiming at this problem, I bring a universal and flexible arithmetic. I relate the design of arithmetic to the design of database, and decompose the formulae, and save the information into database. In the last, I sum up the advantage and disadvantage about the SLA management system.
