| 摘 要： | 随着新型业务类型如视频会议、网络游戏、交互应用等不断涌现,如何利用有限的网络资源进行有效的流量控制,以保障业务的服务质量(Quality of Service,QoS)已成为一个非常迫切的问题。而目前已有的QoS流量控制方法大多存在着对网络资源的利用率低、可靠性差、粒度粗、实现困难,可扩展性差等问题。软件定义网络(Software Defined Network,SDN)提出的控制层与数据层分离思想,为解决此类问题提供了崭新的思路。本文提出了一种基于OpenFlow技术的QoS流量控制方法,利用自适应多约束QoS路由技术,提高了QoS控制的灵活性与可靠性,实现了对网络资源的高效利用和业务流控制的细粒度。最后,我们在OpenvSwitch环境下验证了该方法的有效性。

| Abstract: | With the new application generating such as video conference, online games and interactive applications, how to use the limited network resources with effective flow control to guarantee service quality of service (QoS) has become a very urgent problem. At present, QOS traffic control methods are presented have some problems such as low utilization of network resource, reliability, coarse grain, difficulty of implementation and poor scalability .Software Defined Network (SDN) provides a new idea to solve the problem by separating controlling layer and data layer. In this paper we proposed QoS traffic method based on OpenFlow, using adaptive multi constrained QoS routing technology, which improved the flexibility and reliability of the QoS control, achieved the efficient use of network resources and traffic flow control of fine-grained. Its effectiveness is verified by OpenvSwitch. |
