Abstract: A method and system are provided for continuously monitoring bandwidth utilization in real time on a backbone of a network. Prefixes using the highest traffic can be identified and additional bandwidth can be provisioned in the form of optical transponder wavelengths. The additional bandwidth can be an express path that passes directly through optical nodes (thereby bypassing transit network devices) to the destination optical node. A centralized controller can perform the monitoring of the network devices, decide that an express path needs to be generated, and control both the network device and the optical network nodes to generate the express path from the network device, through the optical network, to the destination network device. The controller can apply and remove IP static routes and IP addresses associated with an express path. Additionally, the controller can request the setup or tear-down of an optical wavelength within the optical network.

Abstract: Techniques for dynamically identifying an optical path to utilize in an optical network in response to a bandwidth request are disclosed herein. In embodiments, router port information, IP address information, and optical transponder information may be obtained by a network controller system from a router controller. An optical network path and a particular wavelength may be obtained from a CDC node controller. The network controller system may instruct an optical transponder controller to configure an optical transponder in the optical network path to utilize the particular wavelength based on obtaining the optical network path. The network controller system may instruct the router controller to configure router ports for one or more routers to utilize the IP address information and the router port information based at least in part on the instructing of the optical transponder controller to configure the optical transponder.
