Abstract:
A network relay device constituting a network includes a frame determination unit for referencing a protocol identifier contained in a frame from an external network relay device constituting another standard network different from the network, to determine whether or not the frame contains a confirmation frame for network operation, administration or maintenance, and a processing unit for performing operation, administration, or maintenance on the frame, when the frame determination unit determines that the frame is the confirmation frame.
