ABSTRACT:
A method of constructing a repair path around a non-available component in a data communications network is described. The data communications network has, as components, nodes and links therebetween defining a network topology. The non-available component is a member of a shared risk group of components commonly renderable non-available. The method comprises the step, performed at a repairing node, of identifying as a repair target a neighbour component of the non-available component. The method further comprises the step of constructing a repair network topology omitting the shared risk group. The method further comprises the step of constructing a repair path to the repair target in the repair topology.
