Abstract
A method to provide high availability in network elements using distributed architectures. The method employs multiple software components that are distributed across data/forwarding plane and control plane elements in a network element. The software components in the data/forwarding plane include active and standby components. Components in the control plane a re provided to communicate with the components in the data/forwarding plane. A keep-alive messaging mechanism is used to monitor operation of the various elements in the network element. Upon detection of a failure to a hardware or software component, the data/forwarding plane and/or control plane elements are reconfigured, as applicable, to replace a failed active component with a corresponding standby component. This enables the network element to be reconfigured in a manner that is transparent to other network elements, and provided high availability for the network element.
