SDQ: Enabling rapid QoE experimentation using Software Defined Networking

Abstract

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.

“…multitasking and multi-watching) and helping users think about negotiable forms of watching [7]. HCI could work more closely with network systems researchers who are experts in, and drive the agenda of, QoE [22,23,25]. Through this partnership, HCI researchers and practitioners could: implement interfaces and services that nudge and shift users towards less demanding modes of watching [51]; be more instrumental in promoting network infrastructure running from renewable energy (e.g.…”
