User latency estimation device, user latency estimation method, and program

摘要

PROBLEM TO BE SOLVED: To estimate users' waiting time, even when a protocol for performing encryption with respect to an application layer, or the like, is used, by reducing the size of acquired data.;SOLUTION: An apparatus for estimating the users' waiting time includes the devices: for acquiring respective packets transmitted to a user terminal from a server providing the service of a TCP base, and storing the packets in a memory together with time information; for calculating the number of the packets by each time slot; for extracting as an extraction time slot group a time slot group where the number of packets is equal to or more than a predetermined detection threshold; for identifying a continuous section being a time section, where the packets continuously appear, while deviating a sliding window in a time progress direction, based on the total time of the extraction time slots included in the sliding window having a prescribed window time length and also on the window time length; and for output of the identified continuous section as the estimated users' waiting time.;COPYRIGHT: (C)2011,JPO&INPIT
