Abstract
A system and method for automatically generating a protection route as an alternative to a working route through a network of switches prior to network failure. A switch selects the proposed protection route so that the protection route is disjoint from the working route. Next, a switch or switches determines whether bandwidth is available for the proposed protection route. If so, the protection route is set-up for activation when needed.
