ABSTRACT:
In a system in which a plurality of nodes are connected using a light wavelength multiplexing connection route which can simultaneously connect nodes using light beams of a plurality of different wavelengths, each node has a cache memory for holding data in memories in other nodes. Some or all of the pieces of information required for data transfer in one node or between the nodes are transferred from the node to an arbiter used in use arbitration of the connection route via one of arbitration optical signal routes for respectively connecting the arbiter and the nodes. The arbiter distributes the transferred information to other nodes, and each node updates the contents of its cache memory on the basis of the distributed information.
