Abstract

A method and mechanism, operating within an application layer of the architectural model of a communications protocol, for maintaining high availability in a computer network utilizing virtual Internet Protocol (IP) addresses. A backup connection is created wherein a second network card is added to a node of a computer network. A failover mechanism operating within the application layer captures an original virtual IP configuration corresponding to a primary network connection of the node and monitors the primary network connection. Upon detecting a failure of the primary network connection, the failover mechanism halts monitoring of the primary connection, captures the current virtual IP configuration of the primary network connection, configures the second network interface with the parameters of the primary network interface, and brings up the second interface. If the current virtual IP configuration was successfully captured, it is used in the configuration of the second interface. If the current virtual IP configuration was not successfully captured, the original virtual IP configuration is used in the configuration of the second interface.
