SYSTEM AND METHOD FOR PREVENTING REPEAT DATA PASSING OVER WHEN UPDATING REPEAT CONTROL INFORMATION AND RECORDING MEDIUM

PROBLEM TO BE SOLVED: To provide a system capable of preventing the data from passing over by parallel operating of a high-speed repeater means when registering repeat information. SOLUTION: This system has a destination determining means 3 for determining the destination of data, to which a destination address non-registered in repeat control information 1 to be used for repeating by a high-speed repeater means 2 is set, according to a procedure determined mutually between repeater equipment when such data are received, repeating of the relevant data, and storing information concerning the relevant destination address in the repeat control information for repeating the data to the relevant destination address through the high-speed repeater means later, the repeat information in the repeat control information is equipped with a permission flag 5 of a flag for judging whether the high-speed repeater means can perform repeating of the data to the relevant destination address or not and when storing the repeat information concerning the destination address of the relevant data in the repeat control information, the destination determining means 3 sets the permission flag of the repeat information into repeat suppression state and cancels the repeat suppression of the data concerning the relevant destination address after the repeat information is completely stored.
