Abstract
First to N-th circuit interface unitstocorresponding to first to N-th circuitstoinclude an input traffic counter unit, etc. and an output traffic counter unit, etc. for counting the traffic of input and output. A traffic counter monitor blockin a control unitspecifies an input traffic counter unitand an output traffic counter unitof two circuitsthrough a switch unitin a specific packet flow, and periodically obtains the count values, based on which the utilization rate, the discard rate, etc. of the corresponding circuitare obtained to monitor the traffic. This makes it possible to monitor packet signal traffic when a plurality of circuits are to be switched without capturing each packet signal.
