Distinguishing between link and node failure to facilitate fast reroute
Abstract
Systems and methods for distinguishing a node failure from a link failure are provided. By strengthening the assumption of independent failures, bandwidth sharing among backup tunnels protecting links and nodes of a network is facilitated as well as distributed computation of backup tunnel placement. Thus a backup tunnel overlay network can provide guaranteed bandwidth in the event of a failure.
