【摘要】 SLA是一个经服务双方谈判而达成的正式协议,它约定了服务质量指标和服务双方的职责,是电信运营商与客户为达到和维持特定的服务质量而协商制定的一套相关目标和过程。SLA可以保证电信运营商和客户双方各自的利益。本文在对网络管理的基本概念、原理、现状及未来趋势分析的基础上,引入了SLA的概念,详细介绍了它的内容及意义,性能规范等。在此基础上深入研究SLA评估理论,涉及网络性能参数到QoS参数的映射机制以及SLA指标的测量方式,并给出了一个实用的SLA性能评估方法。提出一套基于IP网络的SLA评估系统,大致可归类为BSS(业务支撑系统),实现IP网络端到端SLA管理,监测,评估和报告。本系统的研发参考了TMF的SLA管理手册(SLA Management Handbook)以及eTOM业务模型,涉及到J2EE、EJB、XML等或经典或新兴的计算机软件开发技术。更多还原

【Abstract】 SLA is a formal negotiated agreement between the Service Provider and the Customer. It defines the objectives of service quality and contracts the responsibilities for the two parties. An SLA is a set of appropriate procedures and targets agreed between Service Providers and Customers, in order to achieve and maintain specified Quality of Service. SLA may bring advantage for both SP and Customer.A novel Management concept-Service Level Agreement is introduced on the basis of introduction and analysis of the basic concepts, theories and the status of the present and future researches of network management. SLA Evaluating Theories is deeply discussed. In this part the mapping of network performance Metrics into Qos parameters and measurement of SLA metrics is involved, and a set of pratical evaluating method of SLA performance is presented.A set of IP Network SLA Evaluating System is presented in this paper, which is one of the Business Support Systems.The management, monitoring, evaluating and reporting of end-to-end SLA based on IP Network is realized in this system. The system developing consults the TMF SLA Management Handbook, while it involves nowaday softwarete chnologies such as J2EE, EJB, XML, etc.更多还原
