An approach to identifying QoS problems

Abstract

Broadband ISDN will be the vehicle of a great variety of services. The quality of the services provided should be constantly monitored, evaluated and kept within specifications, despite the fact that the information available to QoS monitoring agents is usually limited. In this paper, we examine how performance problems can be resolved by combining the information available to agents that minitor end-to-end QoS performance. We show that a central management system is capable of identifying the cause of performance degradation quickly by correlating the information of many QoS monitoring centres. © 1994.
