Analysis of Fault Tolerance in Peer to Peer Video on Demand System Using V Chaining

The video on demand system is one of the streaming applications widely access remote video programs over the Internet. One of the variant of VoD system is peer to peer (p2p) system. In P2P VoD system peers are frequently fails while chaining. To overcome the failure of peers in chaining fault tolerance mechanism is used. We have proposed VChaining mechanism on Continuous Time Markov Chain model. A birth death process is used to model our proposed mechanism. The parameters used in our model as arrival of requests of peers versus failure of peers, normal versus recovery, the average load on the system, the peer band width and buffer in the system, the server bandwidth and server load. We have simulated above parameters using Video Chaining (V Chaining) mechanism. We have compared simulation results with existing mechanism such as optimal, accelerated chaining mechanism. Our simulation results fairer among all the chaining mechanisms.
