Systems and methods for a preemptive controller for photonic line systems

An optical controller adapted to perform photonic control in an optical network, the optical controller comprising:

• a processor;
• a communications interface communicatively coupled to the processor;
• and
• memory storing instructions that, when executed, cause the processor to
• monitor signal output of the optical controller for fluctuations on a signal, wherein the optical controller operates with one or more upstream optical controllers in the optical network which may cause the fluctuations, and
• initiate a control loop by the optical controller on the signal based on the monitored fluctuations,
• wherein the signal output is monitored and the control loop is initiated based on a plurality of thresholds comprising
• a Monitor Start Threshold (MST) used to start the monitor,
• a Perturbation Acceptance Threshold (PAT) used to initiate the control loop where the PAT is indicative of an ability to converge despite the fluctuations in the signal, and
• a Controller Convergence Threshold (CCT) used to declare convergence of the control loop.

An optical network, comprising:

• a plurality of interconnected Optical Add/Drop Multiplexer (OADM) nodes;
• a plurality of links interconnecting the OADM nodes;
• and
• a plurality of optical controllers configured to perform photonic control, wherein each of the plurality of optical controllers are adapted to
• monitor signal output of an associated optical controller for fluctuations on a signal, and
• initiate a control loop by the associated optical controller on the signal based on the monitored fluctuations,
• wherein the signal output is monitored and the control loop is initiated based on a plurality of thresholds comprising
• a Monitor Start Threshold (MST) used to start the monitor,
• a Perturbation Acceptance Threshold (PAT) used to initiate the control loop where the PAT is indicative of an ability to converge despite the fluctuations in the signal, and
• a Controller Convergence Threshold (CCT) used to declare convergence of the control loop.
