<p>A relay server 20 transmits, to an access management apparatus 30 that manages an access right to a relay server 10, an access request with respect to the relay server 10. The access management apparatus 30 confirms that the access right to the relay server 10 is set in the relay server 20, and then requests the relay server 10 to permit an access by the relay server 20. In a case where the relay server 10 permits the access from the relay server 20, the access management apparatus 30 notifies the relay server 20 of such access permission. Based on the notice from the access management apparatus 30, the relay server 20 establishes a routing session with the relay server 10. By using the routing session, the relay server 20 starts the communication with a general server that serves as a maintenance target.</p> |
