Abstract
In one embodiment, head-end nodes receive a list of tunnels to be rerouted from a particular link of an intermediate node. If a head-end node is unable to reroute a tunnel for which it is the head-end node using conventional distributed routing, each head-end node executes the same algorithm to compute paths for all tunnels in the list (e.g., potentially applying bandwidth scaling).
