A network and QoE aware P2P video streaming solution

Abstract

This paper presents a solution for video streaming in a Peer-to-Peer (P2P) fashion, which takes into account the users' context, including information related to the physical underlying networks (type of access network, topology, Internet Service Provider.), in order to optimize the content delivery. Coupled with this network-aware tree structure, the capability to dynamically adapt video data, by the peers themselves, enable to provide the video in the best possible quality according to the context of the users. Components, launched on the peers, analyse the quality perceived by the end user, namely the QoE (Quality of experience), in real-time in order to reorganize the P2P network in case of insufficient perceived quality. A demonstrator of the solution has been implemented and tests have been done on the PlanetLab network in order to validate the feasibility of such a solution.
