摘要:
一直以来,互联网IP网络的服务质量(Quality of Service, QoS)是研究人员关注的热点问题,提出了一系列理论和解决方案。QoS为各种网络应用提供了带宽、延迟、丢包率等的保证,对多媒体应用至关重要。本文分析了传统QoS技术存在的问题,并提出了利用SDN技术提升网络QoS服务质量的观点。对基于OpenFlow协议提升QoS服务质量的一些关键技术进行了介绍。本文是利用SDN网络实现QoS技术的指南,同时也为其他网络服务在SDN框架下的实现提供了重要的实际借鉴意义。

Abstract: The Quality of Service (QoS) of IP network has been a hot issue concerned by many researchers and they put forward a series of theories and solutions. QoS provides guarantee of bandwidth, delay, packet loss rate, etc. for a variety of network applications and it is essential for multimedia applications. This paper analyzes the problems of traditional QoS technical and realizes the QoS technology based on SDN network. To enhance the quality of service QoS based OpenFlow protocol some key technologies were introduced. This article is a guideline of using SDN network to realize QoS technology; simultaneously it provides important practical reference in implementation of internet service based on the SDN framework.
