| Abstract: | Several service-intrinsic performance metrics for end-to-end SLA (service level agreement) are defined taking into account both human perception requirements and service-intrinsic implementation technologies. In order to verify the SLA compliance an end-to-end SLA performance measurement model which promises better scalability for high-speed network environments is proposed. After describing the functionalities of the main components including meters, front-end processors and analyzer, the workflow of all components is provided to illustrate the time feasibility of the model. A simple algorithm for quantifying the SLA compliance is also presented. |
