摘要
针对业务应用系统对网络传输质量要求的不断提高,通过分析路由交换设备服务质量(QoS)实现机制,研究了报文分类、优先级标识、流量监管、队列调度以及端口限速等多方面的QoS应用技术。最后,从工程实践角度提出了一套完善的QoS部署流程,解决了网际互联协议(IP)网络设备传输在拥塞避免和流量管理方面的问题,从根本上提高了IP网络的服务能力。
Requirement of business application system on network transmission quality is becoming increasingly demanding. This paper analyzes the QoS implementation mechanism of the routing and switching equipment. It also studies the packet classification, priority identification, traffic policing, queue scheduling, port limitrate and other technologies related to QoS application. Finally, the paper proposes a complete set of QoS deployment flows in the framework of engineering practice to solve the problem of congestion avoidance and traffic management in IP network transmission equipment, which can essentially improve service ability of IP network.
