Abstract
A packet processing device includes a memory; and a processor configured to acquire an amount of packets arriving in each first section length as a first sampling value, determine a plurality of temporary periods based on a multiple of the first section length, calculate, for each of the temporary periods, a statistical value obtained by quantifying a bias in the amount of packets arriving in each first section length based on the first sampling value, estimate the temporary period having a maximum statistical value as a neighborhood period, acquire an amount of packets arriving in each second section length as a second sampling value, determine a plurality of neighborhood temporary periods around the neighborhood period, calculate a statistical value for each neighborhood temporary period based on the second sampling value, and estimate the neighborhood temporary period having the maximum statistical value as a true period of the arriving packets.
