2018-00450 - [Campagne CORDI-S-CRI Paris] Optimization of Internet quality of experience in home networks

Despite the steady increase in home broadband speeds, simple tasks such as watching a video streamed over the Internet or having a Skype call can still be a frustrating experience. Overloaded servers, network congestion, and poor home WiFi quality are just a few of the potential root causes that can hamper users’ Internet Quality of Experience (QoE) [1]. Without the knowledge of where the problems might be located and in the hope of improving their experience, users often opt to pay higher fees to their residential Internet provider for increased access capacities. Yet, access link capacity is only one of the many potential bottlenecks impairing Internet quality. The key question to improve Internet QoE is: what is the root cause of Internet QoE impairments? Answering this question is challenging. No single entity (user, access ISP, content provider) has all the information to fully diagnose poor Internet QoE: the content provider can track QoE impairments, but it cannot directly identify the root causes within the network; ISPs have more information about in network issues, but no direct knowledge of Internet QoE.
