<p>An audio-communication bandwidth management system includes a communication connection server and two or more network apparatuses connected to each other via two or more connections on a network. When there is a change in a usage state of one of the connections to other network apparatuses, the network apparatus recalculates bandwidth data for network areas based on the changed usage state and transmits the recalculated bandwidth data to the server. The server references corresponding bandwidth data stored in a database upon receiving an audio-communication line request, and then determines whether normal communication is enabled by comparing the bandwidth data with a required bandwidth calculated based on the audio-communication line request. Then, the server determines whether a line should be permitted based on the determined results, transmits results to a terminal, and updates the database in accordance with the bandwidth data received from the network apparatus.</p> |
