A method and mechanism operating within the Application layer of the architectural model for maintaining high availability in a two node computer network. A backup connection is created wherein a second network card is added to each node of a two node network and a crossover cable is coupled between them. Each backup network card is configured with dummy parameters and taken down upon startup. A failover mechanism operating within the Application layer monitors the original, primary network connection. Upon detecting a failure of the primary connection, the failover mechanism halts monitoring of the primary connection, configures the backup network interface with the parameters of the primary network interface, and brings up the backup interface.
