Abstract:
A method for maintaining high availability in a computer network with a trunked network connection, said method comprising:adding a first High Availability Networking (HAnet) mechanism to a first node of said computer network, wherein said HAnet mechanism operates within an Application layer of an architectural model of said computer network; adding a second trunked network connection to said computer network, wherein said second trunked network connection is between said first node and a second node of said computer network; monitoring a first trunked network connection of said computer network, wherein said first trunked network connection is between said first node and said second node, and wherein said monitoring is by said first HAnet mechanism; detecting a degradation in performance of said first trunked network connection, wherein said degradation is detected by said first HAnet mechanism; performing a failover from said first trunked network connection to said second trunked network connection in response to detecting said degradation exceeds a first threshold, wherein said failover is performed by said first HAnet mechanism; and continuing use of said first trunked network, in response to detecting said degradation does not exceed said threshold.
