Title:
COMMUNICATION LOG AGGREGATION DEVICE AND COMMUNICATION LOG AGGREGATION METHOD
Document Type and Number:
WIPO Patent Application WO/2021/241353
Kind Code:
A1
Abstract:
A communication log aggregation device in a control network system configured from two or more subnetworks, said communication log aggregation device being an aggregation device that is disposed in the control network system and that aggregates a flow record containing flow identification information included in a message flowing to an observation unit disposed in the control network system, and first statistical information for each of flows categorized on the basis of the flow identification information, and comprising: a communication unit (103) that acquires, from each of aggregation devices disposed respectively in the two or more subnetworks, flow information containing one or more flow records and the first statistical information for each flow; and a flow aggregation unit (104) that performs at least one from among selecting the one or more flow records contained in the acquired one or more pieces of flow information, adding second statistical information based on the first statistical information, and deleting the one or more flow records, thereby generating aggregated flow information, and outputs the aggregated flow information that was generated.
