Abstract

Video streaming is often carried out by congestion controlled transport protocols to preserve network sustainability.However, the success of the growth of such non-live video flows is linked to the user quality of experience. Thus, onepossible solution is to deploy complex quality of service systems inside the core network. Another possibility would be tokeep the end-to-end principle while making aware transport protocols of video quality rather than throughput. The objectiveof this article is to investigate the latter by proposing a novel transport mechanism which targets video quality fairness amongvideo flows. Our proposal, called VIRAL for virtual rate-quality curve, allows congestion controlled transport protocols toprovide fairness in terms of both throughput and video quality. VIRAL is compliant with any rate-based congestion controlmechanisms that enable a smooth sending rate for multimedia applications. Implemented inside TFRC a TCP-friendlyprotocol, we show that VIRAL enables both intra-fairness between video flows in terms of video quality and inter-fairnessin terms of throughput between TCP and video flows.
