The optical switches include different types of optical core switch and a plurality of optical-path selection switches. The optical transceivers provided near the processor have a regenerative relay function that regenerates optical signals and turns back the optical signals, and perform optical communication with a communication counterpart via the optical switches.

This optical cut-through can be effectively performed without imposing a signal processing burden that consumes electric power on the processor.
