PROBLEM TO BE SOLVED: To efficiently use a communication path.SOLUTION: A port 1a transmits a frame 5 of a first type to a relay device 2. A port 1b transmits a frame 6 of a second type to the relay device 2. Based on transfer information, a control unit 1d identifies the port 1a to be a transfer destination port of the first type frame 5 to access a node 3 connected to the relay device 2. Thereafter, according to the load of the port 1a, the control unit 1d generates a second type frame 6 including the first type frame 5. The control unit 1d transmits the second type frame 6 from the port 1b, instead of the transmission of the first type frame 5 from the port 1a. |
