Netflix, YouTube, and the like, are now the dominant sources of traffic on the Internet. Recent studies observe that competing adaptive video streams generate flows that lead to instability, under-utilization, and unfairness behind bottleneck links. Additional measurements suggest there may also be a negative impact on users’ perceived quality of experience as a consequence. Intuitively, application-generated issues should be resolved at the application layer. In this presentation I shall demonstrate that fairness, by any definition, can only be solved in the network. Moreover, that in an increasingly HTTP-S world, some form of client interaction is required. In support, a new network-layer ‘QoE-fairness’ metric will be be introduced that reflects user experience. Experiments using our open-source implementation in the home environment reinforce the network-layer as the right place to attack the general problem.
