    摘要： A method and apparatus for performing admission control in a peer-to-peer video-on-demand system are described including determining if there is sufficient bandwidth to support leading sub-clip streaming for a new request from a video playback device, determining if there is sufficient bandwidth to admit the request without sacrificing quality of service for existing requests, accepting admission of the new request if both determining acts are positive and rejecting admission of the new request if either of the determining acts are negative. Also described is an apparatus for providing content to a video playback device in a peer-to-peer video-on-demand system including an admission control unit and a data engine component.

    摘要： A multimedia-on-demand peer-to-peer device acting as a receiving peer includes a local cache memory device adapted to store a multimedia prefix. Local storage of the multimedia prefix allows rapid commencement of playback of the requested multimedia program without substantially loading the streaming capacity of an associated server device. The storage of multimedia prefixes in local cache memory of the receiving peer device can take place during periods of relatively low network loading so as to optimize network and server scheduling. Included is a method and apparatus for performing admission control in a peer-to-peer multimedia-on-demand system. The admission control system determines if there is sufficient system capacity to support a new request from a peer-to-peer device acting as a client in light of the presence of stored multimedia prefixes at the peer-to-peer device acting as a receiving peer device, among other factors.
