Peer-to-peer video delivery scheme for large scale video-on-demand applications

On the basis of the emerging peer-to-peer structure and the characteristics of user behavior, this paper proposes a scalable video delivery scheme, named P2PVD, for large scale video-on-demand application. In P2PVD, two types of orders are permitted: reserved and urgent orders. Reserved orders are encouraged with a lower price policy to smooth the network traffic and the server load. A delay-aware dynamic parallel transmission in the requesting peer is introduced to serve the reserved and urgent orders. The supplying peer is carefully designed based on three priority rules to increase the capacity of P2PVD. Experimental results indicate that P2PVD is scalable.
