Abstract
In a path routing system for a communication network having a plurality of nodes and a plurality of transmission lines, an originate node transmits a routing message with a transmission line attribute designation to a bypass node for establishing a path between the originate node and a terminal node. A repeater node searches for a transmission line having the same attribute as the transmission line attribute designation upon receipt of the routing message with the transmission line attribute designation, and transmits the message to an adjacent node through the searched transmission line. A path between the originate node and the terminal node is autonomously selected to pass through transmission lines having the desired attribute by repeatably searching the transmission lines and transmitting the message between nodes disposed between the originate node and the terminal node.
