METHOD, SYSTEM AND CONTROL PROGRAM FOR STREAM DISTRIBUTION SWITCHOVER, AS WELL AS RECORDING MEDIUM RECORDING STREAM DISTRIBUTION SWITCHOVER CONTROL PROGRAM

摘要

PROBLEM TO BE SOLVED: To provide a method, a system and a control program for stream distribution switcho ver, as well as recording mediums recording stream distribution switchover control program, which does not give rise to any hindrance to stream broadcasting even if the number of distribution requests increases and the number of clients becomes huge.;SOLUTION: The characteristic configuration means is provided with: distribution device management units 11-n1, which keep track of the operational condition and the operational content for respective stream distribution devices 1-n; distribution processing units 12-n2 which are equipped with client information storing unit 12a-n2a in the inside; and a distribution switchover control units C, which determines an optimum stream distribution device which can optimally conduct distribution processing to be conducted in the (one) stream distribution device 1-n after the associated content to be kept track of is collected from the distribution device management units 11-n1 in the respective stream distribution device 1-n, and transfers client information in the stream distribution device to which the relevant distribution processing is conducted until keeping track of the information to a client information storing unit in the optimum stream distribution device 1-n.;COPYRIGHT: (C)2002,JPO
