Video streaming requires reliable transmission and a steady network to satisfy the video users and applications QoS needs. The network service must provide and meet a certain level of performance to accommodating these QoS, specially in Smart City environments, but current Internet best-effort service does not guarantee QoS. Software-defined networking (SDN) is an approach intended to separate the network control and data (forwarding) planes to get better management and optimization, which clearly enhance the planning and development of smart urban communities. In this paper, we propose a dynamic QoS algorithm over SDN to select the optimum path that meets video QoS in order to optimize the quality of experience (QoE). We differentiate the traffic based on video resolution QoE parameters to Standard Definition (SD) and High Definition (HD). The results demonstrate that the proposed method obtained better viewing quality for an smart community environment and increases the overall network throughput.

一种基于 QoS 的软件定义网络路由算法

视频流需要可靠的传输和稳定的网络来满足视频用户和应用的 QoS 需求。网络服务必须提供并满足一定的性能水平来适应这些 QoS,特别是在智慧城市环境中,但当前的 Internet 尽力服务并不能保证 QoS。软件定义网络(SDN)是一种旨在分离网络控制和数据(转发)平面以获得更好的管理和优化的方法,这明显增强了智慧城市社区的规划和发展。在本文中,我们提出了一种基于 SDN 的动态 QoS 算法来选择满足视频 QoS 的最佳路径,以优化体验质量 (QoE)。我们根据视频分辨率 QoE 参数将流量区分为标清 (SD) 和高清 (HD)。
