Abstract:
1. A node device in a network having a plurality of node devices, the node device comprising: an identification information management table configured to store, as information about a frame transmitted by a local node, identification information for unique identification of a frame and information about a destination node of the frame; a destination node weighting table configured to store weighting information about another node as a destination node for relay of the frame for each final destination node of the frame; a frame reception device configured to receive the frame transmitted addressed to the local node from another node; a destination node weighting table update device configured to update data of the destination node weighting table corresponding to the final destination node of the frame for the destination node stored as associated with identification information when an occurrence of a loop or a back-track is detected by comparing the identification information of the frame received by the frame reception device with the identification information stored in the identification information management table; and a frame destination determination device configured to determine another node as a destination node for relay of the frame by referring to the destination node weighting table corresponding to a final destination node of the frame when he identification information about the frame received by the frame reception device is not stored in the identification information management table, wherein the weighting information includes one of an incoming route link weight, an outgoing route link weight, a bidirectional link weight, an incoming route quality weight and an inter-link reach weight.
