摘要

A communication-speed-limited user extraction apparatus for extracting a user whose communication speed is limited based on communication histories includes a communication history storage unit configured to store the communication histories including throughput information on a user-by-user basis; and a communication-speed-limited user determination unit configured to extract a communication history with a same communication environment at a communication date and time within a predetermined period of time from the communication history storage unit and determine that a user with a different throughput distribution is the user whose communication speed is limited.
