摘要
首先根据传统的Qo S应用瓶颈引出多级调度的必要性,然后根据DSL论坛定义的层次化Qo S基本模型提出一个五级调度的调度树模型。该模型可灵活配置调度节点和调度单元,从而实现六级队列灵活调度以及五级的流水调度,确保了调度的效率和速度。最后,在以太网接口上应用该多级调度的模型实现多用户多业务的服务质量,为网络流量管理提供了一种合理的机制。
Firstly, the necessity of the hierarchy QoS for the bottleneck of traditional QoS is introduced. Then it presents a spanning -tree model of five-level scheduling, based on the hierarchy QoS 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 he 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.
