20100268687 | NODE SYSTEM, SERVER SWITCHING METHOD, SERVER APPARATUS, AND DATA TAKEOVER METHOD - A plurality of active servers are connected in cascade such that data synchronized to data of a preceding server is stored in a subsequent server. A standby server stores data synchronized to data of a last one of the plurality of active servers connected in cascade. When any active server fails, servers, from the one subsequent to the failed active server through the standby server, take over services so far provided by the respective preceding servers using data synchronized to the preceding servers. | 10-21-2010 |
20110093604 | COMMUNICATION SYSTEM, SERVER APPARATUS, INFORMATION COMMUNICATION METHOD, AND PROGRAM - The communication system of the present invention includes a terminal, a first server apparatus that manages movement of the terminal, and a second server apparatus that performs authentication of the terminal. The first server apparatus uses an AAA protocol to transmit a first message that includes a pseudo-NAI of the terminal to the second server apparatus. The second server apparatus records the pseudo-NAI and true-NAI of the terminal in association with each other, and upon receiving the first message from the first server apparatus, uses the AAA protocol to transmit to the first server apparatus a second message that includes the true-NAI that was placed in association with the pseudo-NAI that was included in the first message. | 04-21-2011 |
