<p><P>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. <P>SOLUTION: An apparatus for estimating the users' waiting time includes the devices: for acquiring respective packets transmitted to a user terminal from an application server, and storing the packets in a memory; for calculating the number of the packets by each time slot having a predetermined time width; for extracting as an extraction time slot group a time slot group where the number of packets is equal to or more than a detection threshold; for identifying a continuous section, where the packets continuously appear, based on the total time of the extraction time slots included in a sliding window and also on a window time length; for estimating a server processing time with referring to TCP header information in each packet; and for joining the continuous section with the server processing time and for output of the joined time section as the estimated users' waiting time. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
