PERFORMANCE CONTROL OF AGGREGATE QoS NETWORKING PROCESSES

This paper is concerned with the individual and aggregate performance measures for controlling the quality of service processes in a networking environment. The focus is on distinguishing the traffic parameters which are responsible for inducing performance effects and the extent of these effects. Evaluating the level of additional network resources (bandwidth or buffer) ensures that all individual traffic class loss measures will remain below their desired target in settings where only aggregate losses can be observed and controlled. Identifying the traffic parameters differentiating between the individual and aggregate traffic classes allow to derive packing rules on how the traffic can be safely multiplexed into a common service class in order to have a controllable performance.
