THE RESEARCH ON DISTRIBUTED PACKET SCHEDULING METHOD FOR AN INPUT AND OUTPUT QUEUING SWITCH
一种输入输出排队交换机中分布式分组调度方法的研究

In this paper, a distributed packet scheduling algorithm called DHIOS(Distributed Hierarchical Ingress and Output Scheduling) is presented and simulated for an input and output queuing switch whose switch fabric is a shared memory. The distributed packet scheduling algorithm can support variable length packets and guarantee the QoS (Quality of Service) of flows. The simulation on OPNET shows that the distributed packet scheduling algorithm has good performance.
