Publication number: 20120151059Abstract: A first relay server transmits, to an access management apparatus that manages an access right to a second relay server, an access request with respect to the second relay server. The access management apparatus confirms that the access right to the second relay server is set in the first relay server, and then requests the second relay server to permit an access by the first relay server. In a case where the second relay server permits the access from the first relay server, the access management apparatus notifies the first relay server of such access permission. Based on the notice from the access management apparatus, the first relay server establishes a routing session with the second relay server. By using the routing session, the first relay server starts the communication with a general server that serves as a maintenance target.Type: ApplicationFiled: August 11, 2010Publication date: June 14, 2012Applicant: MURATA MACHINERY, LTD.Inventors: Yoshifumi Tanimoto, Kazuo Soumiya, Keisuke Nishimura, Suguru Suzuki
