Abstract: A queue scheduling with polling and reservation strategy for the network node is designed.Because the delay sensitive traffic and the non-delay sensitive traffic need the different qualities of service(QoS),they will gain the different services through scheduling appropriate transmission rates.A three-dimensional Markov queue model is proposed to investigate the queue scheduling.The queue is analyzed by using a method of matrix-geometric solution.The performance index are derived,including the mean queue length,mean waiting time and throughput of both the delay sensitive traffic and the non-delay sensitive traffic,and the blocking probability of the delay sensitive traffic is also obtained.
