Abstract

A software-defined network multi-layer controller (SDN-MLC) may communicate with multiple layers of a telecommunication network. The SDN-MLC may have an optimization algorithm that helps manage, in near real-time, the multiple layers of the telecommunication network.

First claim

What is claimed:

1. An apparatus comprising:
a processor; and
a memory coupled with the processor, the memory storing executable instructions that when executed by the processor cause the processor to effectuate operations comprising:
obtaining multiple layer information associated with multiple layers of a telecommunications network, the multiple layer information comprising optical layer information and router layer information;
based on the multiple layer information, anticipating a need of a component of the optical layer or the router layer; and
based on the anticipating of the need of the component of the optical layer or the router layer,
providing instructions to ordering system that comprise ordering one or more spares of the component.

2. The apparatus of claim 1 , wherein the instructions are provided to a software-defined network controller for changing configurations for reconfigurable optical add-drop multiplexers (ROADMs).

3. The apparatus of claim 1 , wherein the instructions further comprise implementing a configuration change of the router layer that comprises a configuration of a routing table.

4. The apparatus of claim 1 , wherein the instructions further comprise implementing a configuration change of the optical layer that comprises a configuration of a tail.

5. The apparatus of claim 1 , wherein the instructions further comprise implementing a configuration change of the optical layer comprises a configuration of an optical regenerator.

6. The apparatus of claim 1 , wherein the instructions further comprise implementing a configuration change of the optical layer that comprises a configuration change of a reconfigurable optical add-drop multiplexer.

7. The apparatus of claim 1 , wherein the instructions further comprise implementing a configuration change of the optical layer that comprises an addition of a wavelength channel of a reconfigurable optical add-drop multiplexer.

8. The apparatus of claim 1 , wherein the optical layer information comprises an outage alarm.

9. The apparatus of claim 1 , wherein the optical layer information comprises a load along an optical path.

10. A method comprising:
obtaining, by a device, multiple layer information associated with multiple layers of a telecommunications network, the multiple layer information comprising optical layer information and router layer information;
based on the multiple layer information, anticipating, by the device, a need of a component of the optical layer or the router layer; and
based on the anticipating of the need of the component of the optical layer or the router layer,
providing, by the device, instructions that comprise ordering one or more spares of the component.

11. The method of claim 10 , wherein the instructions are provided to a software-defined network controller for changing configurations for reconfigurable optical add-drop multiplexers (ROADMs).

12. The method of claim 10 , wherein the instructions further comprise implementing a configuration change of the router layer that comprises a configuration of a routing table.

13. The method of claim 10 , wherein the instructions further comprise implementing a configuration change of the optical layer that comprises a configuration of a tail.

14. The method of claim 10 , wherein the instructions further comprise implementing a configuration change of the optical layer comprises a configuration of an optical regenerator.

15. The method of claim 10 , wherein the instructions further comprise implementing a configuration change of the optical layer that comprises a configuration change of a reconfigurable optical add-drop multiplexer.

16. The method of claim 10 , wherein the instructions further comprise implementing a configuration change of the optical layer that comprises an addition of a wavelength channel of a reconfigurable optical add-drop multiplexer.

17. The method of claim 10 , wherein the optical layer information comprises an outage alarm.

18. The method of claim 10 , wherein the optical layer information comprises a load along an optical path.

19. A system comprising:
a reconfigurable optical add-drop multiplexer;
a router; and
a software-defined multi-layer controller communicatively connected with the router and the reconfigurable optical add-drop multiplexer, the software-defined multi-layer controller comprising:
a processor; and
a memory coupled with the processor, the memory storing executable instructions that when executed by the processor cause the processor to effectuate operations comprising:
obtaining multiple layer information associated with multiple layers of a telecommunications network, the multiple layer information comprising optical layer information;
based on the multiple layer information, anticipating a need of a component of the optical layer or the router layer; and
based on the anticipating of the need of the component of the optical layer or the router layer,
providing instructions to ordering system that comprise ordering one or more spares of the component.

20. The system of claim 19 , the operations further comprising
determining a configuration change of the component based on an estimated time of repair, wherein the estimated time of repair is associated with repair of the optical layer or the router layer; and
based on the determining the configuration change of the component based on the estimated time of repair, providing instructions to effectuate a change of configuration of the component.
