Research on Model of Multi-level Scheduling

Firstly,the necessity of the hierarchy Qo S for the bottleneck of traditional Qo S is introduced. Then it presents a spanning-tree model of five-level scheduling,based on the hierarchy Qo S base model defined by DSL forum. By configuring the scheduling node and the scheduling unit flexibly,the six-level queue scheduling and five-level pipeline scheduling can be realized,besides,the efficiency and speed are guaranteed as well. In the end,the five-level scheduling is applied in Ethernet interface to realize the quality of service for multi-customer and multi-service,providing a reasonable scheme for the traffic management.
