Service Level Agreement (SLA) is thereby proposed to manage telecom services with guaranteed QoS and to address the QoS issues between Service Providers (SP) and users. SLA representation template, violation process and metrics evaluation are three key techniques to implement SLA. A typical SLA management system includes SLA data management, SLA problem management, and SLA management. SLA research is still in its primary stage and SLA management is yet to be standardized With general and special management approaches to be defined in the future, the unified industry standard will finally take shape.展开更多
