摘　　要：针对现有IP承载网中重要业务存在服务质量保证不足的问题,文章分析了基于Diffserv的QoS部署方案。通过业务流量分类、拥塞管理为不同的业务在网络中做转发等级区分,保障关键业务能够处于优先转发的队列(PQ)之中,获得优先转发权限,同时平衡其他重要业务,采用加权轮询调度(WRR),在拥塞预防方面,采用加权随机早期检测(WRED),最终形成PQ+WRR+WRED的端到端QoS部署方案以供参考。Aiming at the problem of insufficient quality of service guarantee for important services in existing IP Bearer networks,this paper analyzes the QoS deployment scheme based on DiffServ.Through traffic classification and congestion management,forwarding levels are differentiated for different services in the network to ensure that key services can be placed in the queue of priority forwarding(PQ) and obtain priority forwarding authority,while balancing other important services.Weighted polling scheduling(WRR) is adopted.In terms of congestion prevention,weighted random early detection(wred) is adopted.Finally,an end-to-end QoS deployment scheme of PQ + WRR + wred is formed for reference.
