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 or router layer information;
based on the multiple layer information, determining that an outage has occurred in the telecommunications network, wherein the outage is associated with a first tail comprising a first router port and a first transponder, wherein the first router port is connected with the first transponder via a dynamic fiber cross connect;
based on the determined outage, determining a configuration of a second tail to resolve the outage; and
based on the determining of the configuration of the second tail, sending a message to the dynamic fiber cross connect in order to implement the configuration.

2. The apparatus of claim 1 , the operations further comprising updating a tail database comprising the first tail and the second tail.

3. The apparatus of claim 1 , the operations further comprising, based on the determining of the configuration of the second tail, sending a message to a router comprising the first router port in order to implement a configuration change associated with the router port.

4. The apparatus of claim 1 , the operations further comprising, based on the determining of the configuration of the second tail, sending a message to a router comprising the first router port in order to implement a configuration change associated with the router port, wherein the configuration change associated with the router port comprises an internet protocol address that is the same as the first router port.

5. The apparatus of claim 1 , wherein the apparatus is a software-defined network multi-layer controller.

6. The apparatus of claim 1 , the operations further comprising, based on the determining of the configuration of the second tail, sending a message to a router comprising the first router port in order to implement a configuration change associated with the router port, wherein the configuration change associated with the router port comprises tunneling configuration that is the same as the first router port.

7. The apparatus of claim 1 , wherein the second tail comprises the first router port and a second transponder.

8. The apparatus of claim 1 , wherein the second tail comprises a second router port and the first transponder.

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 or router layer information;
based on the multiple layer information, determining, by the device, that an outage has occurred in the telecommunications network, wherein the outage is associated with a first tail comprising a first router port and a first transponder, wherein the first router port is connected with the first transponder via a dynamic fiber cross connect;
based on the determined outage, determining, by the device, a configuration of a second tail to resolve the outage; and
based on the determining of the configuration of the second tail, sending, by the device, a message to the dynamic fiber cross connect in order to implement the configuration.

11. The method of claim 10 , further comprising updating a tail database comprising the first tail and the second tail.

12. The method of claim 10 , further comprising, based on the determining of the configuration of the second tail, sending a message to a router comprising the first router port in order to implement a configuration change associated with the router port.

13. The method of claim 10 , further comprising, based on the determining of the configuration of the second tail, sending a message to a router comprising the first router port in order to implement a configuration change associated with the router port.

14. The method of claim 10 , further comprising, based on the determining of the configuration of the second tail, sending a message to a router comprising the first router port in order to implement a configuration change associated with the router port, wherein the configuration change associated with the router port comprises an internet protocol address that is the same as the first router port.

15. The method of claim 10 , wherein the second tail comprises a second router port and the first transponder.

16. The method of claim 10 , wherein the second tail comprises the first router port and a second transponder.

17. The method of claim 10 , wherein the optical layer information comprises a transponder location.

18. The method of claim 10 , wherein the device is an optical layer software-defined network controller.

19. 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 or router layer information;
forecasting a network condition based on machine learning that uses the multiple layer information;
based on the forecast, determining that the network condition may be avoided based on configuration changes of the telecommunications network; and
based on the determining of the configuration changes, sending a message to a device in order to implement the configuration changes.

20. The apparatus of claim 19 , wherein the optical layer information is obtained from a dynamic fiber cross connect and the routing layer information is obtained from a router.
