Preemptive Controller for Photonic Line Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional approaches to managing multiple photonic controllers in optical networks face challenges in maintaining stability, particularly in large mesh networks, due to complex messaging, sequential operation difficulties, and damped responses that fail to minimize signal fluctuations.
Innovation Solution
A preemptive controller system that monitors signal output fluctuations and initiates control loops based on specific thresholds, allowing independent operation without messaging, and dynamically adjusts convergence thresholds to match fluctuating conditions, thereby minimizing simultaneous control actions and maintaining network stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If multiple photonic controllers operate concurrently in optical networks, then control responsiveness and convergence speed are improved, but system stability deteriorates due to simultaneous control actions amplifying signal fluctuations
Solution Approach 1:
The patent implements a preemptive check mechanism that monitors signal fluctuations before a controller initiates control actions. By detecting fluctuations in advance and preventing control loop initiation when fluctuations exceed a threshold, the system avoids simultaneous control actions that would amplify signal variations, thus maintaining stability while allowing concurrent operation of multiple controllers
Solution Approach 2:
The patent employs a feedback mechanism where controllers continuously monitor signal fluctuations at their output and use this information to decide whether to initiate or delay control actions. This feedback loop enables controllers to adapt their behavior based on real-time signal conditions, preventing instability caused by concurrent operations while maintaining fast convergence when conditions permit
2Stability of the object's composition
If controllers use damped responses to avoid simultaneous actions, then signal fluctuations are reduced, but control convergence speed deteriorates due to slowed response
Solution Approach 1:
Instead of using damped responses that slow down control actions, the patent implements a preemptive check that prevents control loop initiation before fluctuations can be amplified. This approach maintains full controller responsiveness and convergence speed by avoiding simultaneous actions through predictive monitoring rather than reactive damping
Solution Approach 2:
The patent uses a simple threshold-based decision mechanism rather than complex damping algorithms. The preemptive check compares signal fluctuations against a threshold and makes a binary decision to initiate or delay control actions, providing stability without the computational overhead and response delays associated with damped control responses
3Device complexity
If controllers operate independently without messaging, then system complexity is reduced and scalability is improved, but coordination between controllers deteriorates leading to simultaneous control actions
Solution Approach 1:
The patent enables controllers to operate independently by implementing a preemptive check mechanism that each controller executes autonomously. Controllers monitor their own output signal fluctuations and make independent decisions about whether to initiate control actions, eliminating the need for inter-controller messaging or coordination while maintaining stability through self-regulation
Solution Approach 2:
By implementing preemptive checks that monitor signal fluctuations before control actions are initiated, each controller can independently determine when it is safe to act. This preliminary monitoring enables independent operation without messaging while preventing simultaneous control actions that would cause instability

AI summary
Systems and methods for an optical controller in an optical network for photonic control include monitoring signal output of the optical controller for fluctuations on a signal, wherein the optical controller may operate with one or more upstream optical controllers in the optical network which may cause the fluctuations; and initiating a control loop by the optical controller on the signal based on the monitored fluctuations. The initiating is based on one or more thresholds used to differentiate actions of the one or more upstream optical controllers of the plurality of optical controllers from one or more of fiber faults, natural fluctuations in fiber plant, and natural fluctuations in hardware.
