Bulldozer: A Cooperative P2P-Based Distribution Platform for User-Centric Content Dissemination

摘要

Because of marketing demand of user-centric video dissemination, promoting video content via interactive distribution platforms has received considerable attention recently. In addition, the preferences of clients are heterogenous and dynamic, effectively utilizing the network bandwidth to distribute user-centric content becomes a challenging problem, especially when the number of users in the systems scale up. Therefore, we propose a P2P-based distribution platform, called Bulldozer, which enable clients to cooperatively propagate user-centric video content in a large scale environment, and better utilizes peers upload bandwidth to share the server traffic load. Bulldozer consists of two components: 1) Clip Scheduling phase schedules the playing order of videos for each individual user, and 2) Bandwidth Allocation phase allocates users upload bandwidths to distribute videos among clients. Finally, simulation results show that Bulldozer can effectively reduce the peak traffic load of the server.
