ABSTRACT:
At least three control patterns are used for a connection management control of nodes in a ring network, each node determining a changeable communication status in accordance with a communication status of the own node and the nature of the control pattern received from an upstream node. The own node transmits one of the control patterns, selected in accordance with the changes in the communication status, to the downstream node. The control patterns indicate respective conditions of the own node so that the communication enable status of the ring network, as a whole, can be autonomously established by the nodes per se without employing a monitor node or supervisory node.
