Abstract
Enhanced messaging is described to support status notifications regarding backup nodes of a data communications network. In one example, a status of a network node at the network node is monitored. The network node is coupled to a network. It is determined that the node is operating in a backup state, and a backup alive packet is sent through the network in response to determining that the node is operating in a backup state.
