Towards ISP-acceptable P2P delivery systems for user generated contents

Peer-to-Peer (P2P) delivery systems, such as eDonkey, Bittorrent, attracted many people who want to share files. Other P2P systems, used for broadcasting video contents, also gained in popularity (e.g., Live systems such as PPLive, PPStream, UUSee, etc.). In the past few years, new streaming applications, initially designed for User Generated Contents (UGC) have come up and are now widely used to share video contents (e.g., Youtube, Hulu, etc.). Their growing success raises the question of the delivery architecture: will a client/server model still be of good quality? In this paper, we advocate the migration of such applications towards a P2P delivery architecture for scalability and quality purposes. A huge amount of the network traffic is currently related to P2P and UCG applications. However, most of the contents are illegal and therefore badly perceived by majors, governments and ISPs. Furthermore, because of the traffic load it generates in the network, ISPs do not really like it. In this paper, we propose a system that could be acceptable for ISPs since it aims at controlling that only legal contents are distributed and at reducing and optimizing the use of the network, via an active role played by ISPs in the peer selection process. Experiments we have performed in a real-life configuration environment proved the feasibility and efficiency of the proposed solution.
