Abstract

A method of constructing a repair path around a non-available component in a data communications network having, as components, nodes having a network address and links there between comprises the step, performed at a participating node, of receiving from a notifying node in the network, a notification identifying the notifying node and components through which the notifying node can be reached. The method further comprises the step of deriving, from the notification, a network repair address for use in the event of non-availability of a component identified in the notification. The method further comprises the step of constructing a repair path for the repair address.
