Abstract: A method to estimate, in a communication system that includes a first communication device that executes a service, a second communication device that communicates with the first communication device via a network, and a monitoring device that monitors the network, quality of the service executed by the first communication device, includes obtaining a packet transmitted in a predetermined direction over the network, classifying the obtained packet into a packet of a first type and a packet of a second type different from the packet of the first type, and determining a feature for each type of the classified packet, and estimating the quality of the service executed by the first communication device by using a training model trained by using the feature and the quality of the service at timing when the packet used to determine the feature is transmitted, by processor circuitry.
