OTN RATE ADJUSTMENT SYSTEMS AND METHODS FOR CONTROL PLANE RESTORATION, CONGESTION CONTROL, AND NETWORK UTILIZATION
First Claim
1. A method in an Optical Transport Network (OTN) network, comprising:
- provisioning an end-to-end path with a defined committed information rate (CIR) and a peak information rate (PIR) via an optical control plane;
computing a path for the end-to-end path based on the CIR and the PIR;
configuring the end-to-end path on the computed path at an Optical Channel Data Unit (ODU) data rate supporting the PIR if the computed path can support the PIR or at the ODU data rate supporting the CIR if the computed path can support the CIR and not the PIR; and
adjusting the ODU data rate of the end-to-end path based on a rate adjustment requirement in the OTN network and based on the CIR and the PIR.

Abstract
A method, a controller, and an Optical Transport Network (OTN) network include provisioning an end-to-end path with a defined committed information rate (CIR) and a peak information rate (PIR) via an optical control plane; computing a path for the end-to-end path based on the CIR and the PIR; configuring the end-to-end path on the computed path at an Optical Channel Data Unit (ODU) data rate supporting the PIR if the computed path can support the PIR or at the ODU data rate supporting the CIR if the computed path can support the CIR and not the PIR; and adjusting the ODU data rate of the end-to-end path based on a rate adjustment requirement in the OTN network and based on the CIR and the PIR.

11. A controller, comprising:
-
a processor; memory storing instructions that, when executed, cause the processor to; receive a request for an end-to-end path with a defined committed information rate (CIR) and a peak information rate (PIR) in an Optical Transport Network (OTN)-based network; compute a path for the end-to-end path based on the CIR and the PIR; cause the end-to-end path to be configured on the computed path at an Optical Channel Data Unit (ODU) data rate supporting the PIR if the computed path can support the PIR or at the ODU data rate supporting the CIR if the computed path can support the CIR and not the PIR; and cause the ODU data rate to be adjusted based on a rate adjustment requirement in the OTN-based network and based on the CIR and the PIR. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18)

19. A Optical Transport Network (OTN)-based network, comprising:
-
a plurality of interconnected nodes operating an optical control plane therebetween; an end-to-end path controlled by the optical control plane with a defined committed information rate (CIR) and a peak information rate (PIR) implemented through at least two of the plurality of interconnected nodes; and a controller configured to cause the end-to-end path to adjust an Optical Channel Data Unit (ODU) data rate based on a rate adjustment requirement in the OTN-based network and based on the CIR and the PIR. - View Dependent Claims (20)
