Abstract
A node may determine a failure in a first path for routing first optical network traffic between a first set of networking devices, where the first path includes a first set of optical transport nodes. The node may determine a second path for routing the first optical network traffic between the first set of networking devices, where the second path includes a second set of optical transport nodes that route second optical network traffic between a second set of networking devices. The second set of optical transport nodes may include at least one node that is not included in the first set of optical transport nodes. The node may pre-empt routing of the second optical network traffic via the second path, and may route the first optical network traffic via the second path after pre-empting routing of the second optical network traffic via the second path.
