Abstract

PURPOSE:To decrease the number of channel devices for connection of node terminals of a computer system by using a node terminal device to store and exchange data. CONSTITUTION:For a system where plural HOSTs which perform different jobs are connected to plural hosts which perform processes proper to areas via nodes and an optical loop, a node terminal device has a store/exchange function. When data are sent to a HOSTa from a HOST1, node 1 receives and stores data after receiving a WRITE input/output action from a channel device of the HOST1 and then releases the channel device. Then the node 1 puts the stored data on the optical loop. A node (a) fetches data from the optical loop and applies an interruption to the channel device of the HOSTa. The channel device of the HOSTa carries out a SENCE input/output action and a READ input/output action after detecting the interruption and then fetches data. The node (a) releases the channel device after the fetching of data is through and informs the release of the chnnel device to the node 1 of the remote side. The node 1 reports this release information to the HOST1 and discontinues a connection state to the node (a).
