视频流量体验质量的优化

Optimization of Quality of Experience for Video Traffic

Qahhar Muhammad Qadir, Alexander A. Kist, Zhongwei Zhang

摘要:

向视频点播和实时的信息系统的快速转变已经影响了移动网络以及有线网络。研究界非常关注优化视频流量的体验质量(QoE),主要是因为视频在互联网用户中很受欢迎。已经在不同的方向上提出了技术,以改善视频用户的感知。本文研究了一种新的跨层架构的性能优化的视频流量的QoE。所提出的架构相比,其他两个架构,非自适应和自适应。对于前者,视频流量在没有自适应的情况下发送,而对于后者,视频源调整其传输速率。两种方法在视频会话的平均意见分数、会话数、延迟、丢包率、抖动和利用率方面进行了比较。大量的仿真结果表明,所提出的架构优于非自适应和自适应架构的视频流量。

英文摘要:

The rapid shift toward video on-demand and real time information systems has affected mobile as well as wired networks. The research community has placed a strong focus on optimizing the Quality of Experience (QoE) of video traffic, mainly because video is popular among Internet users. Techniques have been proposed in different directions towards improvement of the perception of video users. This paper investigates the performance of a novel cross-layer architecture for optimizing the QoE of video traffic. The proposed architecture is compared to two other architectures; non-adaptive and adaptive. For the former, video traffic is sent without adaptation, whereas for the later video sources adapt their transmission rate. Both are compared in terms of the mean opinion score of video sessions, number of sessions, delay, packet drop ratio, jitter and utilization. The results from extensive simulations show that the proposed architecture outperforms the non-adaptive and adaptive architectures for video traffic.
