Zusammenfassung:	PROBLEM TO BE SOLVED: To provide the local area network management system that acquires a token efficiently and copes with data requiring urgent transmission. SOLUTION: A master station 1-1 and plural slave stations 1-2-1-n are connected to a transmission line 3, the master station sends a transmission request recovery frame to each slave station and each slave station adds priority information set to its own data to the transmission request recovery frame received from the master station and sends the result. The master station receives the transmission request recovery frame to which priority information for each of data of each slave station is added and decides the station that permits transmission of the data transmission frame for each of data based on the priority information for each of the data of each slave station in the received transmission request recovery frame.
