Abstract

For a flooded packet transmitted from a first base to a second base connected to a transport network, a first edge node in the transport network first sets path selection information for selecting a return path for transmitting a packet from the second base to the first base, and then transmits the packet to the second base via the path configured in advance. When receiving the flooded packet, a second edge node selects the return path on the basis of the path selection information from a plurality of path candidates configured in advance between the first base and the second base and learns the path in association with information indicating the transmission source.
