Popularity based distribution schemes for P2P assisted streaming of VoD contents

Abstract

The Video on Demand (VoD) service is becoming a dominant service in the telecommunication market due to the great convenience regarding the choice of content items and their independent viewing time. However, it comes with the downsides of high server storage and capacity demands because of the large variety of content items and the high amount of traffic generated for serving each request. Storing part of the popular contents on the peers brings certain advantages but, it still has issues regarding the overall traffic in the core of the network and the scalability. Therefore We propose a P2P assisted model for streaming VoD contents that takes advantage of the clients unused uplink and storage capacity to serve requests of other clients and present popularity based schemes for distribution of both the popular and unpopular contents on the peers with the objective to reduce the streaming traffic in the core of the network, improve the responsiveness of the system and increase its scalability
