Abstract:
1. A communication device comprising: a receiving unit configured to receive a data frame and an OAM frame via a connected packet network; a transmitting unit configured to transmit the received frames and a self-originating OAM frame to the packet network; a monitoring unit configured to monitor a flow rate of the transmitted frames, the monitoring unit being configured to calculate a transmission cycle of the OAM frame that compensates for a shortfall in a number of the transmitted frames based on a number of the data frames, a number of the OAM frame and a predetermined threshold; an OAM control unit configured to cause a transmission cycle of the self-originating OAM frame to be a predetermined transmission cycle set for a normal condition when the flow rate of the transmitted frames is greater than or equal to the predetermined threshold, and to cause the calculated transmission cycle to be the transmission cycle of the self-originating OAM frame when the flow rate of the transmitted frames is less than the predetermined threshold.
