KEYWORDS Video on demand (VoD), Peer to Peer (P2P), Live streaming

Video on demand is a popular multimedia application on the internet. Now a day's peer to peer video on demand is the most popular technique that captures most of the users on the internet. Therefore, we have proposed a video on demand based on the peer to peer network and also defined a detailed working principle of peer to peer video on demand using chaining mechanism. In comparison to it, we have also considered some of the existing approaches that use chaining mechanism for the transmission of video streams for the video on demand system. To our proposed video on demand system architecture, we have proposed Video Chaining (V-Chaining) mechanism that enhances the performance of the chaining mechanism in terms of bandwidth, buffer in both server and peer load. Hence, we have derived an analytical model for different performance metrics for our mechanism and the same is simulated to have fairer comparisons between the existing mechanism and with our mechanism. The result of the simulation shows that our mechanism fairs better in all aspects of performance metrics than the existing mechanism such as standard, advanced, optimal and accelerated chaining.
