Abstract

See full text

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.
