Why does this matter operationally?
Resilience
The capacity of a connectivity system to maintain acceptable service levels when components fail, links degrade, or conditions change unexpectedly. Resilient architectures use redundancy, failover paths, and graceful degradation to keep operations running when ideal conditions cannot be guaranteed.

Error Detection
Error Detection is the process of identifying whether data has been altered or corrupted. It is used to confirm that information arrived intact.
Protocol
Ethernet
Ethernet is a family of wired networking technologies used for local area communication that defines framing, addressing, and physical connectivity for device communication on local networks.

Exclusive Economic Zone Routing
Exclusive Economic Zone Routing is routing or service planning that accounts for Maritime jurisdiction boundaries and regulatory conditions within an exclusive economic zone. It links routing choices to Maritime legal…
Operations
Fade Margin
Fade margin is the amount of extra received signal level or link budget beyond the minimum required to maintain service during expected fading conditions.
Concept/Framework
Fail Safe
Fail Safe is a design principle in which a system defaults to a safe state when a failure or abnormal condition occurs. It prioritizes safety over continued operation.
Operations
Fail-Operational System
Fail-Operational System is a system designed to continue operating after a fault, often with reduced capability rather than immediate shutdown. It preserves operation through failure conditions.
Operations
Failover
Failover is the transfer of service from a failed component or path to a standby or alternate one to preserve continuity during outages or faults.
Operations
Failure Domain
A failure domain is the set of components or functions that share a common risk of concurrent failure because they depend on the same underlying element.
Concept/Framework
Fallback Routing
Fallback Routing is the use of alternate routes when a primary communications or network path is unavailable or unsuitable. It preserves service continuity through another path.
