<p>A communication system using a network route establishing technique for a network having a plurality of nodes (11 to 18) connected through links (21 to 31), in which a route search message is delivered simultaneously in a plurality of directions from a sender node (11) through a network route to a destination node, and a confirmation is delivered from the destination through the network route back to the sender node, and accordingly, a network route is established. The communication system includes a device for detecting, at a node (13) through which a search message is to be transmitted, a possibility of a transmission of the search message beyond the node (13), a device for delivering a cancel message in the direction from which the search message has been transmitted, and a device for releasing the network route engaged by the search message, based on the delivered cancel message. <IMAGE></p> |
