20090307288 | BACKUP DEVICE - The backup server in the backup site receives messages multicast from business servers in the primary site, extracts the business data, and stores it in backup databases for each business server. Upon this storing of business data, the sequence numbers in the messages are added to the business data to be stored in the backup databases. Detection of loss in sequence numbers allows the detection of which piece of the business data is lost. The backup server does not request a business server in the primary site to retransmit data even when business data is partially lost, but instead directly requests the database server in the primary site to transmit the lost business data. | 12-10-2009 |
20100014520 | COMMUNICATION METHOD FOR SYSTEM INCLUDING CLIENT DEVICE AND PLURAL SERVER DEVICES - An objective of the present invention is to secure the continuity of the communication between a client device and a standby server device, when a failure occurs and switch to the standby device is performed. A communication processing unit of the client device establishes connection with a plurality of server devices simultaneously by transmitting a UDP packet to the plurality of server devices by multicast. After establishing the connection, data of the application is transmitted by multicast to the plurality of the server devices. In the even of a failure, a standby server device receives the data packet multicast from the client device to continue the inter-application communication. | 01-21-2010 |
