Abstract
A method and mechanism operating within the Application layer of the architectural model for maintaining high availability in a computer network utilizing trunking technology. A backup connection is created wherein a second multi-port network card is added to a node of a computer network. A failover mechanism operating within the Application layer monitors an original, primary trunked network connection. Upon detecting a degradation in performance of the primary trunked connection that exceeds a threshold, the failover mechanism halts monitoring of the primary trunked connection, configures the second multi-port network interface with the parameters of the primary multi-port network interface, and brings up the second interface.
