Resilience

Path Congestion Path congestion is the state in which a network path experiences traffic demand that approaches or exceeds its effective capacity, resulting in degraded performance. It is a path-level performance condition. Concept/Framework Path Diversity Path diversity is the design condition in which a network has more than one independent path available between endpoints or service domains. It is used to improve resilience, traffic distribution,… Concept/Framework Path Loss Path loss is the reduction in received radio signal power that occurs because the signal must propagate through space and the surrounding environment. It is a fundamental factor in RF… Concept/Framework Path Selection Path selection is the process of evaluating available network paths and choosing the one that best matches policy, performance, or resilience requirements. It may operate continuously or in response to… Concept/Framework Permissive Logic Permissive Logic is control logic that confirms conditions are satisfied before allowing an action or sequence to proceed. Operations Phase Alignment Phase Alignment is the adjustment of signal or clock phases so they are synchronized or matched within a desired tolerance. Operations Phase Noise Phase noise is the undesirable short-term fluctuation of a signal’s phase around its nominal value. It appears as spectral spreading around a carrier and is a key metric of signal… Concept/Framework Physical Isolation Physical isolation is the architectural practice of separating systems or zones so that communication or access requires crossing a deliberate physical boundary. It is used to contain risk, protect critical… Concept/Framework PID Controller PID Controller is a feedback controller that uses proportional, integral, and derivative terms to regulate a process toward a desired setpoint. It is widely used in control systems. Operations Plant-Wide Control Network Plant-Wide Control Network is the communications infrastructure that connects control systems, devices, and operator systems across an entire plant to coordinate control, monitoring, and supervisory functions throughout the facility.
