Abstract
With the widespread use of dynamic adaptive streaming over HTTP (DASH) for delivering videos in the Internet, assuring an acceptable quality of experience (QoE) to the end-user is vital. Due to the use of conventional TCP for DASH, the QoE gets affected by well-known characteristics of mobile networks. MultiPath TCP (MPTCP), an extension of TCP, addresses the several limitations of TCP by utilizing the bandwidth on two or more network paths simultaneously. In this work, we investigate the influence of MPTCP on the QoE in mobile networks. We implement three common DASH adaptation algorithms on an emulated DASH over TCP testbed and assess the QoE using objective metrics. The experimental results demonstrate a significant improvement in the QoE by using MPTCP for DASH.
