SLA实现技术及其应用

随着网络服务的内容越来越丰富，用户对服务质量（QoS）的要求也越来越高。为了管理提供QoS保证的电信业务，服务等级协定（SLA）被提出，用来解决用户和服务提供商间有关QoS保证的问题。SLA表示模板、违例处理和指标评价是SLA的3种关键的实现技术。一个典型的SLA管理系统通常包括SLA数据管理、SLA问题管理和SLA管理3个部分。SLA的研究还处于起步阶段。需要进一步规范SLA管理内容。定义通用性和专用性相结合的管理方法，形成统一的工业标准。

SLA Implementation Technologies and Their Applications

With more and more network services developed, network customers now have higher requirements on the Quality of Service (QoS). In order to manage the telecom services supporting QoS, Service Level Agreement (SLA) is proposed to solve the problems about QoS between the customer and the service supplier. The presentation template, violation disposal and index evaluation are three SLA key implementation technologies. A typical SLA management system generally includes 3 units: SLA data management, SLA problem management and SLA management. The research of SLA is still in the primary stage. It is necessary to further specify the contents of SLA management, to define the generality-specialization-combined SLA management methods, and to make a unified SLA standard finally.
