摘要： PROBLEM TO BE SOLVED: To quicken the write-in of data to a storage medium and the readout of data from the storage medium by reducing the delay of frame transfer. SOLUTION: A number of hop decision part 312 decides whether or not the number of hops stored in the header part of a frame input from a C port 311 or a C port 313 is 2 or more. Then, when the number of hops is 2 or more, a number of hop decision part 312 subtracts 1 from the number of hops, and restores it in the header part of the frame, and outputs from a C port 313 or a C port 311 opposed to the port to which the frame is input. Meanwhile, when the number of hops is 1, the number of hop decision part 312 outputs the frame to the port decision part 315. The port determination part 315 acquires the transmission destination address from the header part of the frame, and determines the port corresponding to the transmission destination address to the output port of the frame by referring to a routing table 314.
