A traffic information aggregating apparatus (hereinafter an aggregating apparatus) receives traffic information from a network apparatus. The aggregating apparatus generates aggregated data in which the traffic information for each previously determined aggregation time is aggregated, and stores the aggregated data into an aggregated data management table correspondingly to an aggregation identifier. The aggregating apparatus determines, at the interval of the aggregation time, whether a difference between the aggregated data and a base value is within a previously determined range, and accumulates, in the case where it is within the range, the aggregated data to corresponding accumulated data of the aggregated data management table, and resets the aggregated data. In the case where it exceeds the range, the aggregating apparatus exports the aggregated data and/or the accumulated data of the aggregated data management table to the monitor server.
