Abstract
When transmitting an R-APS (NR) frame, a control frame processing unit sets a priority setting value arbitrarily set by a user as a value of a node ID region. A ring control unit compares priority based on a value of the node ID region of the R-APS (NR) frame transmitted from its own device and a value of the node ID region of the R-APS (NR) frame transmitted from a different device, and the ring control unit determines whether a ring port is maintained in a block state or changed from the block state to an open state based on a result of the comparison.
