Patent abstract
Methods and apparatus for rerouting network traffic are described herein. In one embodiment, an example of process includes maintaining as a part of a routing table of a network element information regarding one or more backup links leading to a node using label switched protocols (LSPs), the node being adjacent to the network element, and in response to a failure of a primary link coupling the network element to the node, the network element rerouting network traffic to the node via the one or more backup paths without having to notifying and waiting for a response from a headend node that originates the network traffic. Other methods and apparatuses are also described.
