Abstract
In an embodiment, an apparatus for forwarding data in a data communications network having as components nodes and links therebetween comprises a network interface configured to couple to a data communications network having as components nodes and links therebetween; first logic which when executed is operable to receive a repair address; second logic which when executed is operable to compute a repair path from a repairing node to the repair address around a failure component on a primary forwarding path between the apparatus and a repairing node; and third logic which when executed is operable to propagate the repair address along a label switched path (LSP), comprising the repair path, to the repairing node. The apparatus offers improved efficiency in computing a repair path in a network around a failed component because unnecessary computations are not performed with the disclosed apparatus and approach.
