Abstract :
We consider a priority cell scheduling in the following scenario. High-speed cell networks accommodate constant bit rate (CBR) streams from real-time sources and unspecified bit rate (UBR) streams from non real-time sources. The real-time traffic requires guarantees of its delay time. On the other hand, the non real-time traffic is relatively tolerable to its delay time. We obtain the queueing delay distribution of cells from CBR streams. Further the average queueing delay of cells from UBR streams is obtained in some special cases. We provide some numerical results and discuss the effectiveness of quality-of-service (QoS) guarantees based on the statistical bound and the influence of UBR streams on the system performance
