IPC: H04L12/42
Filed: 1991-05-21
Abstract: PURPOSE:To guarantee time required for data transmission by storing the transmitting station addresses of data together with priority levels when a receiving- busy state is generated and successively executing the receiving processing of data n the received order of the data. CONSTITUTION:At the time of receiving data to a transmission control station 17 itself through a transmission line 21, the station 17 stores the address of the data in a data transmitting station in an address latch part 22. When the reception of the data is impossible, the transmission station address stored in the latch part 22 is stored in a receiving-busy table 23 together with its receiving priority order. A comparing part 24 compares the address in the latch part 22 with the data transmitting station address having the highest receiving priority order and stored in the table 23. When both the addresses coincide with each other as the result of comparison, a reception control part 25 executes receiving processing.
