Background and Motivation Important issues currently not addressed Hard bounds on recovery times Using signalling for fault notification in large-scale WDM networks would not scale well Long process for recovery if we use signaling to activate the protecting Label Switched Paths Provisions in proposed draft Ability to reach nodes on protection paths within time constraint Scalability: Bundling of fault information by initiating protection of all relevant LSP’s using per-fault notification as opposed to per-LSP protection Increased options for protection paths to increase sharing
