摘要：PURPOSE: A VOD(Video On Demand) server is provided to transmit high definition video and audio data to clients by using low priced distributed proxy servers which does not impose a large load on a network. CONSTITUTION: The system comprises a VOD multicast transmission server, and a switching agent. The VOD multicast transmission server includes a HEN(Head End Node) near a client side which stores data requested by one client, and instantly transmits the stored data to other client without connecting the client to a server if the stored data is requested. The switching agent checks the video data stored at all the HENs and the data on the clients requesting the video data, and plans a proper HEN rearrangement strategy.
