Flexible channel coordination for multiple optical carrier optical networks

摘要

One or more management systems coordinate wavelength configuration patterns of a plurality of multi-wavelength optical transport nodes in an optical network for a first transport period. The one or more management systems determine data traffic demand changes in the optical network; and coordinate wavelength configuration patterns of the plurality of multi-wavelength optical transport nodes in the optical network for a second transport period, that is subsequent to the first transport period, based on the determined data traffic demand changes.

1. A method, comprising:
assigning, at a network device for a first transport period, a first multiple optical wavelength configuration pattern to multiple transport cards and multiple Reconfigurable Optical Add/Drop Multiplexers (ROADMs) in an optical network; receiving, at the network device, a first notification related to a first traffic demand change request for the optical network; assigning, at the network device for a second transport period based on receipt of the first notification, a second multiple optical wavelength configuration pattern to the multiple transport cards and the multiple ROADMs in the optical network, wherein the second multiple optical wavelength configuration pattern is different from the first multiple optical wavelength pattern and wherein the second transport period is subsequent to the first transport period; and instructing the multiple transport cards and the multiple ROADMs to switch from the first multiple optical wavelength configuration pattern to the second multiple optical wavelength configuration pattern at the second transport period.
