    In client-side segmented cache based P2P VOD system, statically cached video files in peers' disks can efficiently improve data acquisition rate. However, since disk space in a single peer is very limited, it becomes a key problem to design reasonable strategies for replacing those data segments. We start at studying the three VOD system models, and analyze the necessity of utilizing segmented sto... View full abstract»

    Embarrassingly parallel grid applications require no inter-worker interaction. Thus, the underlying communication infrastructure is based on the simple but well understood client/server execution model. This is no longer sufficient if more demanding parallel applications that require true peer-to-peer interaction are to be deployed on grids. In this paper, we propose the industrial-strength eXtens... View full abstract»
