Traffic flow derivation device, traffic flow derivation method, and computer program

摘要

PROBLEM TO BE SOLVED: To derive the traffic volume of a route between a starting point and a destination point based on a flow rate observed at a fixed point. A traffic flow derivation device has a reception unit that receives information indicating traffic volume at each of a plurality of different observation points measured by passive measurement, and information indicating a plurality of traffic volumes received by the reception unit. Based on the time-series data of, some nodes in the network are used as observation nodes, and the network tomography function, which is a method for deriving the internal state of the network from the behavior of packets sent and received between the observation nodes, is used. , A first derivation unit for deriving a first traffic volume, which is a traffic volume of a route between a starting point and a destination, is provided.
