摘　　要：随着计算机网络的快速发展,对于抖动,延迟,带宽敏感的视频、语音等业务越来越多的在网络中传输,这对于网络设备提出了更高的服务质量保证要求。为了对数据传输性能提供不同的质量承诺和服务,网络设备广泛使用QoS技术来保证传输质量及带宽分配提高网络利用率,基于BCM芯片方案,对二层以太网报文的QoS出口行为进行了研究,介绍了BCM方案所支持的6种调度算法SP、RR、WRR、WDRR、SP+WRR、SP+WDRR,并利用Test Center网络测试仪实现了6种调度算法的QoS解决方案。With the rapid development of computer network,jitter,delay,bandwidth sensitive video,voice and other services are increasingly transmitted in the network,which puts forward higher services quality assurance requirements for network equipment.In order to provide different quality of service for the traffic,network equipment widely uses QoS technology to ensure the quality of transmission and bandwidth and improve network utilization.This paper studies the QoS egress behavior of Layer 2 ethernet packets based on the BCM chip scheme,introducing the six scheduling algorithms supported by the BCM scheme,such as SP,RR,WRR,WDRR,and SP+WRR/WDRR and utilizing TestCenter to achieve the QoS solution of the six scheduling algorithms.
