Abstract

A method of managing an optical service in a node utilizing a flexible grid for optical spectrum includes utilizing a Media Channel (MC) model to manage a portion of optical spectrum on an optical line, the MC model includes first frequency information which define the portion of optical spectrum; utilizing a Network Media Channel (NMC) model to manage the optical service and to model a path of the optical service in the MC model, the NMC model has frequency information and port connection information for the optical service; and programming hardware in the node based on the MC model and the NMC model to implement the optical service.

Claims (31)

1. A method of managing an optical service in a node utilizing a flexible grid for optical spectrum, the method comprising:

utilizing a Media Channel (MC) model to manage a portion of optical spectrum on an optical line, the MC model includes first frequency information which define the portion of optical spectrum;

utilizing a Network Media Channel (NMC) model to manage the optical service and to model a path of the optical service in the MC model, the NMC model includes second frequency information and port connection information for the optical service; and

programming hardware in the node based on the MC model and the NMC model to implement the optical service.

2. The method of claim 1 , wherein the MC model has a plurality of NMC routed therein each with its own NMC model.

3. The method of claim 1 , wherein the MC model is a Trail Termination Point (TTP).

4. The method of claim 1 , wherein the NMC model includes two models with a first model to model a port for the optical service and a second model to model a path of the optical service in the MC model.

5. The method of claim 4 , wherein the first model is a Connection Termination Point (CTP) and the second model is a Cross Connection (CRS).

6. The method of claim 1 , wherein the optical line is an Optical Multiplex Section and there are one or more MC models for the optical line.

7. The method of claim 1 , wherein the MC model has one or more NMC models related thereto for associated optical services in an MC associated with the MC model.

8. The method of claim 1 , further comprising utilizing a connection function model to manage cross-connection between MC models and/or NMC models.

9. A node configured to manage an optical service in an optical network utilizing a flexible grid, the node comprising:

one or more optical ports connected to physical layer components; and

a controller configured to

utilize a Media Channel (MC) model to manage a portion of optical spectrum on an optical line, the MC model includes first frequency information which define the portion of optical spectrum,

utilize a Network Media Channel (NMC) model to manage the optical service and to model a path of the optical service in the MC model, the NMC model includes second frequency information and port connection information for the optical service, and

program the one or more optical ports and/or the physical layer components based on the MC model and the NMC model to implement the optical service.

10. The node of claim 9 , wherein the MC model has a plurality of NMC routed therein each with its own NMC model.

11. The node of claim 9 , wherein the MC model is a Trail Termination Point (TTP).

12. The node of claim 9 , wherein the NMC model includes two models with a first model to model a port for the optical service and a second model to model a path of the optical service in the MC model.

13. The node of claim 12 , wherein the first model is a Connection Termination Point (CTP) and the second model is a Cross Connection (CRS).

14. The node of claim 9 , wherein the optical line is an Optical Multiplex Section and there are one or more MC models for the optical line.

15. The node of claim 9 , wherein the MC model has one or more NMC models related thereto for associated optical services in an MC associated with the MC model.

16. The node of claim 9 , wherein the controller is further configured to utilize a connection function model to manage cross-connection between MC models and/or NMC models.

17. A non-transitory computer-readable storage medium comprising instructions that, when executed, cause a processor to perform the steps of:

utilizing a Media Channel (MC) model to manage a portion of optical spectrum on an optical line, the MC model includes first frequency information which define the portion of optical spectrum;

utilizing a Network Media Channel (NMC) model to manage the optical service and to model a path of the optical service in the MC model, the NMC model includes second frequency information and port connection information for the optical service; and

programming hardware in the node based on the MC model and the NMC model to implement the optical service.

18. The non-transitory computer-readable storage medium of claim 17 , wherein the MC model has a plurality of NMC routed therein each with its own NMC model.

19. The non-transitory computer-readable storage medium of claim 17 , wherein the MC model is a Trail Termination Point (TTP).

20. The non-transitory computer-readable storage medium of claim 17 , wherein the NMC model includes two models with a first model to model a port for the optical service and a second model to model a path of the optical service in the MC model.
