QUALITY ESTIMATION METHOD, QUALITY ESTIMATION APPARATUS, AND RECORDING MEDIUM
First Claim
1. An quality estimation method executed by a processor included in a quality estimation apparatus, the method comprising:
- obtaining a plurality of packets communicated between a client device at a first point and a server device;
extracting a number of losses indicating the number of lost packets among the plurality of packets by analyzing the plurality of packets;
determining statistics information of a delay time due to packet loss of the plurality of packets, based on the number of losses and quality information indicating quality of a network used for communication between a client device at a second point and the server device; and
estimating a response time of the server device on operation performed by the client device at the second point based on the determined statistics information.

11. A quality estimation apparatus comprising:
-
a memory; and a processor coupled to the memory and configured to; obtain a plurality of packets communicated between a client device at a first point and a server device; extract a number of losses indicating the number of lost packets among the plurality of packets by analyzing the plurality of packets; determine statistics information of a delay time due to packet loss of the plurality of packets, based on the number of losses and quality information indicating quality of a network used for communication between a client device at a second point and the server device; and estimate a response time of the server device on operation performed by the client device at the second point based on the determined statistics information.

12. A non-transitory computer-readable recording medium that causes a quality estimation apparatus to execute a process, the process comprising:
-
obtaining a plurality of packets communicated between a client device at a first point and a server device; extracting a number of losses indicating the number of lost packets among the plurality of packets by analyzing the plurality of packets; determining statistics information of a delay time due to packet loss of the plurality of packets, based on the number of losses and quality information indicating quality of a network used for communication between a client device at a second point and the server device; and estimating a response time of the server device on operation performed by the client device at the second point based on the determined statistics information.
