Abstract:

Based on study of requirement for service QoS (quality of service) monitoring, a SLS-based (service level specification based) QoS monitoring mechanism was proposed. The QoS monitoring of specific services and the assessment of QoS according to their SLSs were performed with the mechanism. With higher efficience, flexibility and scalablity, there exist SLS layer, network layer and node layer in the so called layered-based mechanism architecture. In addition, when considering both subjective and objective facts of QoS, the violation of QoS consistency was presented according to continuous degradation of performance indexes. The quantitative representation of service satisfaction level was also defined.

Key words: quality of service, service level specification, quality of service monitoring, quality of service conformance
