Abstract
A network includes node devices each storing a table that manages paths to plural gateway devices for connecting to another network. A node device generates a hello frame for specifying a main gateway device of the node device at a predetermined timing, and transmits the hello frame to adjacent node devices. The node device, upon receiving a hello frame from an adjacent node device operating as a first hop destination of a data frame destined for the main gateway device, determines whether quality of a path to the main gateway device is lowest among paths to the plural gateway devices, based on path quality information included in the hello frame. When the quality of a path to the main gateway device is lowest, the node device changes the main gateway device to a gateway device that is registered in the table and specified by information included in the hello frame.
