摘要:
 文中主要研究基于软件定义网络的业务流的优化控制,通过面向用户体验质量(Quality of Experience,QoE)的驱动,引入QoS匹配和优化模型,采用最终用户之间的服务和通信参数的协商机制,根据约定的服务配置分配用于提供业务流传输的网络路径.文中基于软件定义网络的概念,网络的逻辑控制功能和高层策略可以通过中央控制器灵活地进行动态管理和配置,以达到集中式的多用户路径分配的优化.为此,提出建立一种新型的业务流控制模型,从而使多媒体业务流采用最好的服务配置在最佳可用的路径上传递,最终实现总体QoE最大化的目标.
Abstract:
 In this paper,study the optimization of service-flow control based on software defined network,through Quality of Experience (QoE)-driven,introducing a QoS matching and optimization models,adopting the negotiation of service and network communication pa-rameters between end-users,assign the network paths that are used for delivering multimedia flows according to the agreed service config-uration. Based on the concept of software defined networks,the logical control functions and high-level policy of the network can be dy-namically managed and configured flexibly by the central controller,in order to achieve a centralized multi-user optimization of the path assignments. Therefore,propose a new service-flow control model that allows delivering multimedia service-flow over the best available path using the best service configuration,in order to achieve the goal of maximizing the overall QoE.
