PROBLEM TO BE SOLVED: To provide a MAC study correction system capable of properly transferring a frame to a switch of a moving destination without waiting for an aging timeout time (usually 5 minutes) by correcting the study information of each switch in the time of terminal movement relating to the MAC study correction system. SOLUTION: The system is configured by providing a study correction frame transmitting means 3 for performing the Unicast transmission of a study correction frame to a port corresponding to old study information when a transmission destination MAC address of a received frame is already studied and a transmission source MAC address is re-studied in a network providing a LAN service via a switch 1, and a study correcting means 4 for transmitting the study correction frame to the port corresponding to the old study information after re-studying a reception port when a transmission source MAC address is already studied and the study port is different at the time of receiving the study correction frame.
