Abstract

The emerging network paradigm of Software Defined Networking (SDN) has been increasingly adopted to improve the Quality of Experiences (QoE) across multiple HTTP adaptive streaming (HAS) instances. However, there is currently a gap between research and reality in this field. QoE models, which offer user-level context to network management processes, are often tested in a simulation environment. Such environments do not consider the effects that network protocols, client programs, and other real world factors may have on the outcomes. Ultimately, this can lead to models not functioning as expected in real networks. On the other hand, setting up an experiment that reflects reality is a time consuming process requiring expert knowledge. This paper shares designs and guidelines of an SDN experimentation framework (SDQ), which offers rapid evaluation of QoE models using real network infrastructures.

SDQ:使用软件定义网络实现快速QoE实验
软件定义网络(SDN)的新兴网络范例已被越来越多地用于提高跨多个HTTP自适应流(has)实例的体验质量(QoE)。然而,目前该领域的研究与实际存在差距。QoE模型为网络管理过程提供用户级上下文,通常在模拟环境中进行测试。这样的环境没有考虑网络协议、客户端程序和其他现实世界因素可能对结果产生的影响。最终,这可能导致模型在实际网络中不能像预期的那样运行。另一方面,建立一个反映现实的实验是一个耗时的过程,需要专业知识。本文分享了SDN实验框架(SDQ)的设计和指导方针,该框架可以使用真实的网络基础设施对QoE模型进行快速评估。
