Abstract

We developed a novel scheme to maintain QoS (Quality of Service) requirement for different traffic classes in the dynamic environment through full utilization of statistical multiplexing. Previous designs on measurement-based admission control mainly focused on strategies that consider the worst case traffic source model to guarantee QoS bounds for all connections. This can result in overallocation of resources. The proposed mechanism not only allows statistical multiplexing gain to be exploited, it also simplifies the estimation process. An accurate formula for the cell loss probability which is combined with measurements, is presented for a new traffic model. Furthermore we enhance the performance of this mechanism through real-time measurements of traffic and monitoring of QoS.
