Abstract

Disclosed herein are methods and systems for generating and/or obtaining at least one loading policy for a transmission line segment that is currently operating, the at least one loading policy comprising a combination of loading parameters for one or more types of loading management operations associated with the transmission line segment. At least one of the loading policies may be activated on a network element of the transmission line segment. Upon receiving a loading request to change a spectral loading pattern of the transmission line segment, current loading data of the transmission line segment and loading parameters from the activated loading policy may be obtained and used to generate a loading response. A signal containing the loading response may be sent to the network element, the signal configured to cause the network element to change the spectral loading pattern of the transmission line segment based on the loading response.

First claim

What is claimed is:

1 . A system, comprising:
a network element having a processor and a non-transitory computer readable memory storing instructions that, when executed by the processor, cause the network element to:
obtain and store at least one loading policy for a transmission line segment that is currently operating, the at least one loading policy comprising a combination of loading parameters for one or more types of loading management operations associated with the transmission line segment;
activate at least one of the at least one loading policy;
receive a loading request to change a spectral loading pattern of the transmission line segment;
obtain current loading data of the transmission line segment;
obtain loading parameters from the at least one of the at least one loading policy that was activated;
generate a loading response based at least in part on the current loading data and the loading parameters from the at least one of the at least one loading policy that was activated; and send a signal containing the loading response, the signal configured to change the spectral loading pattern of the transmission line segment based on the loading response.

2 . The system of claim 1 , wherein the loading parameters comprise one of more of a region in an optical spectrum where the spectral loading pattern of the transmission line segment is to be changed, a maximum power change allowed due to loading; a loading factor for a given range of current loading; an allowable loading limit for a given range of current loading;
whether to consider loading criteria; topology of the transmission line segment; and load balancing.

3 . The system of claim 1 , wherein the one of more types of loading management operations comprise service activation, service deactivation, band activation, band deactivation, segment activation, and segment deactivation.

4 . The system of claim 1 , wherein the at least one loading policy for the transmission line segment is generated using a user device.

6 . The system of claim 5 , wherein a first signal containing a command to activate the at least one of the at least one loading policy was sent from the user device to the network element via the network, the signal causing the network element to activate the at least one of the at least one loading policy.

7 . The system of claim 6 , wherein a second signal containing the loading request to change the spectral loading pattern of the transmission line segment was sent from the user device to the network element via the network.

8 . An optical receiver in accordance with claim 6 , wherein the semiconductor alloy includes AlGaInAs.

9 . The system of claim 1 , wherein the current loading data of the transmission line segment includes characteristics of the transmission line segment including at least one of a type of amplifier, a fiber type, offsets that are being configured, and number of spans.

10 . The system of claim 1 , wherein the network element is a network administration device and the signal containing the loading response is sent to an optical node of the transmission line segment, the signal configured to cause the optical node to change the spectral loading pattern of the optical network segment based on the loading response.
