Abstract
Systems and methods for fast restoration in a network using a control plane include detecting a failure on a link associated with the node; and providing failure information through in-band data path overhead of an affected connection, wherein the in-band data path overhead is sent over a fast path, wherein the failure information is received at an originating node of the affected connection via the fast path, prior to the originating node receiving control plane signaling via a slow path relative to the fast path.
