Abstract
To improve the application layer multicast data distribution efficiency, this paper presented one kind of hybrid application layer multicast model based on the virtual P2SP( peer to server & peer)VPHM.The model created a four-layer data distribution structure.From top to bottom was the service node layer, super node layer, the virtual service layer, Peer node layer.The multicast domain including the top three layers was employed to ensure the breadth of multicast, while the VP2SP (virtual P2SP) domain including the lowest two layers was used to ensure the depth of the multicast.Simulation results show that the model reduces the control overhead and cuts down the average end to end delay, which is suitable to those large scale ALM applications with high quality of service guaranteed.关键词
