Abstract

In this demonstration we extend our recent work - "D-LiTE: A platform for evaluating DASH performance over a simulated LTE network". With D-LiTE we stream actual DASH content between real physical clients and an Apache2 server, over a simulated NS3-LTE air interface in real-time. We enhance our platform to encompass both an Software Defined Network (SDN)-enabled backhaul and an SDN-enabled WIFI router attached to the backhaul. Similar to data offloading in most ISP networks, with D-LiTE-ful we demonstrate how distributing video flows to local WIFI networks improves achievable Quality of Experience (QoE) not only for the clients moving to the WIFI hotspot but also for the remaining clients on the LTE network. Based on feedback from both a "Panoramic UI" which provides a mechanism for LTE and Client parametrisation, and a means of viewing the output of their interactions, and an "SDN UI" which offers packet level information and illustrates routing behaviours in the backhaul, we observe real-time variation in both network conditions and improvement in client QoE. The demonstration showcases how an SDN-enabled multifaceted ISP network can provide dynamic offloading between LTE and WIFI networks by offering a means of local caching, temporary re-routing of TCP flows and centralised control.
