Optical Line Spectral Loading Policies for Error-Free Reconfiguration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing optical communication systems face challenges in configuring spectral loading due to user errors in parameter settings, leading to potential failures and the need for software updates with each change, which is inefficient and prone to errors.
Innovation Solution
A loading management system that provides an automated framework for dynamically creating, installing, and activating loading policies to configure spectral loading patterns in optical transmission line segments, using a network element with a processor and memory to manage loading parameters and operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If operators manually configure loading parameters in the presentation layer, then flexibility in configuring spectral loading is improved, but user errors occur and reliability deteriorates
Solution Approach 1:
A loading policy manager acts as an intermediary between the presentation layer and system software, validating loading parameters before execution. This mediator captures loading requests, checks them against predefined policies, and only executes validated parameters, thereby maintaining operator flexibility while preventing errors from reaching the system core.
2Reliability
If pre-programmed parameters are used in system software, then reliability is improved by avoiding user errors, but adaptability deteriorates as changes require software updates
Solution Approach 1:
The system transitions from static pre-programmed parameters to dynamic loading policies that can be modified and activated without software updates. Loading policies are stored in a database and can be dynamically created, modified, and activated through the presentation layer, allowing the system to adapt to changing requirements while maintaining reliability through policy validation.
3Adaptability or versatility
If multiple loading parameters are made configurable, then adaptability is improved, but device complexity increases
Solution Approach 1:
The complex set of loading parameters is segmented into modular loading policies, where each policy encapsulates a specific set of related parameters for a particular loading scenario. This segmentation allows operators to configure only the relevant policy for their needs rather than managing individual parameters, reducing perceived complexity while maintaining full configurability.

AI summary
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.
