Resilience

Redundant Control Network Redundant Control Network is a control communications network with alternate paths, links, or components so control traffic can continue after a failure. Operations Redundant Path A redundant path is a secondary network path configured or available to preserve service when the primary path fails, degrades, or becomes congested. It is used to improve availability and… Concept/Framework Redundant Subsystem Redundant Subsystem is a backup or duplicate subsystem that can maintain or restore function if the primary subsystem fails. It adds fault tolerance through duplication. Hardware Relay A relay is a communications element that receives a signal and transmits it again toward the destination or next hop. It may operate as an amplifier, repeater, regenerator, or packet-forwarding… Hardware Remote Diagnostics Remote diagnostics is the process of analyzing remote telemetry, status, or event data to determine the condition or fault state of a system. It supports fault identification, troubleshooting, and response… Operations Remote Operations Remote operations is the management of assets, processes, or services from a distant control location using communications, telemetry, and supervisory tools. It may include oversight, control action, troubleshooting, and escalation. Operations Remote Terminal A Remote Terminal is a communications endpoint located away from the central site and connected through a network. It serves as a remote point of access or service interaction. Hardware Remote Terminal Unit A Remote Terminal Unit is a field device that collects telemetry and communicates control or status data for remote operations, commonly used in SCADA systems to extend monitoring and control… Hardware Resilience Resilience is the ability of a system to withstand disruption, recover from faults, and adapt to changing conditions while maintaining acceptable operation. Operations Retransmission Retransmission is the sending of data again after a loss or failed delivery attempt. It is a reliability mechanism used when initial transmission is not successful. Protocol
