Abstract
A centralized controller provides dynamic end-to-end network path setup across multiple network layers. In particular, the centralized controller manages end-to-end network path setup that provisions a path at both the transport network layer (e.g., optical) and the service network layer (e.g., IP/MPLS). The centralized controller performs path computation for an optical path at the transport network layer and for a path at the service network layer that transports network traffic on the underlying optical transport path, based on information obtained by the centralized controller from the underlying network components at both layers.
