A method of searching for an available path in a mesh architecture in a multinode transmission system having a plurality of node apparatuses is disclosed. In setting a shortest path between first and second node apparatuses, the identity of a destination node and the immediate adjacent path along the shortest path from a source node are registered as path management data, for the source node, in a path management table. The identity of a destination node and the immediate adjacent path along the shortest path from each relay node is registered as path management data, for each relay node, in a path management table. Searching for an available path between two node apparatuses is performed on the basis of the path management data in the path management table. By limiting each data registration for each respective node to a destination and immediate path, the memory space for maintaining path management and control and the time required to search for an available path are reduced.
