FIELD: information technology.
SUBSTANCE: node device and programme for simple structures autonomously select an appropriate path without exerting a load on a network. In a node device in a communication network, a FID for uniquely identifying a frame and information about a frame destination node are stored in a FID management table, and weighting information about another node as a recipient for relaying the frame to each final destination node of the frame is stored in a weighting table. When the frame transmitted to a local node is received and if the FID of the received frame is stored in the FID management table, data about the destination node associated with the FID are updated. If the FID frame received from the frame receiving device is not stored in the FID management table, the FID management table corresponding to the frame destination node is checked and another node is defined as the recipient for relying the frame.
EFFECT: reduced load on the network.
