Abstract

See full text

A failover procedure for a computer system includes steps for routing traffic from a routing device to a first server, storing in the routing device data representing a fingerprint of the first server, receiving periodically at the routing device a status message from the first server, detecting at the routing device an invalid status message from the first server by absence of the fingerprint in a status message from the first server within a predetermined time period after last receiving a valid status message, and routing the traffic from the routing device to a second server in response to detecting the invalid status message from the first server. A redundant server system implementing the failover procedure may include servers each capable of generating its fingerprint by reading current system configuration data.
