Today, the management of massive data collections draws much attention as data grids have been developed to deal with large computational problems and provide the opportunity for sharing geographically distributed resources for large‒scale data‒intensive applications. Therefore, finding an effective approach to discover data resources in order to promote better interactions between application communities...
Video-on-demand (VoD) service has been greatly enhanced with the maturation of both peer-to-peer (P2P) and network coding (NC) technology. Digital video cassette recording (VCR) function provides users with more freedom that they can choose different playback modes while viewing video clips. Besides, users are able to switch between different scenes with the support of video-segmentation. Based on...
Although coding over P2P is effective in some ways, coding at routers can bring us more significant benefits. Unfortunately, routers in todaypsilas network are mostly not capable of network coding. We propose a novel scheme to equip routers with coding functionalities. To do this, we design a routing protocol based on network coding and regulate the coding functionalities at routers. Simulation results...
VCR functionality is difficult to be implemented in a P2P VoD system, since it may give more server workload and fails some distribution paths. In this paper, we first analyze the user behavior of VCR interaction, and propose a video segmentation-aided P2P VoD System with VCR functionality. The simulation results show that our mechanism could reduce the server workload and improve the VCR performance...
