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

Free registration required

Executive Summary

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. The authors have proposed V-Chaining mechanism on Continuous Time Markov Chain model. A birth death process is used to model their proposed mechanism. The parameters used in their 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.
