一种输入输出排队交换机中分布式分组调度方法的研究

THE RESEARCH ON DISTRIBUTED PACKET SCHEDULING METHOD FOR AN INPUT AND OUTPUT QUEUING SWITCH

针对采用共享缓存(shared memory)做为交换机构(switching fabric)的输入输出排队交换机,该文给出了一个分布式分组调度方法DHIOS(Distriduted Hierarchical Ingress and OutputScheduling)并做了详细的仿真。表明DHIOS可以支持变长分组,能够确保业务流的QoS,性能优良。

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.
