Abstract: A network relay apparatus includes: a clock generation circuit, a processing circuit, a load detector and a clock cutoff circuit. The clock generation circuit is configured to generate a clock signal having periodical clock pulses. The processing circuit is configured to operate in synchronism with the clock pulses, in order to process data that is to be relayed by the network relay apparatus. The load detector is configured to detect a load of processing by the processing circuit. The clock cutoff circuit is configured to cut off supply of the clock pulses from the clock generation circuit to the processing circuit in order to partially eliminate the clock pulses at a rate corresponding to the load detected by the load detector and to provide the clock signal having the partially eliminated clock pulses to the processing circuit.
