An information processing apparatus is configured to acquire first communication amount information indicating a first communication amount per unit period of time of each of a plurality of flows at a first timing, specify a predictive communication amount per the unit period of time of each of the plurality of flows at a second timing later than the first timing, acquire second communication amount information indicating a second communication amount per the unit period of time of each of the plurality of flows at the second timing, specify a difference between the predictive communication amount and the second communication amount, specify a priority degree of each of the plurality of flows based on the difference and a topology value determined for each of the plurality of flows, and analyze the data traffic of a specific flow selected from the plurality of flows based on the priority degree.
