Abstract:
1. A system for making a replication decision in a Peer-to-Peer Video-on-Demand (P2P VoD) architecture, the system comprising: a plurality of peers; a server maintaining a replication indicator for each of a plurality of videos distributed over the peers, wherein the replication indicator for each video indicates a redundancy, inadequacy or balance of replication of the video; wherein each of the peers reports to the server first information regarding one or more first videos of the plurality of videos which are stored in the peer and reports second information that includes a downloading rate of a second video of the plurality of videos which has been viewed at the peer; and wherein the server determines, according to the first information, the second information and the replication indicators for the one or more first videos and the second video, whether the peer is to replace at least one of the one or more first videos with the second video when the peer does not have enough space for storing the second video; and wherein the server determines the replication indicator for the second video using the downloading rates for the second video reported to the server by all the peers at which the second video has been viewed.
