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.

Split Horizon
Split Horizon is a routing rule that prevents a router from advertising a route back out of the same interface or direction from which the route was learned.
Protocol
Spoofing
The deliberate transmission of falsified signals designed to deceive a receiving system into accepting fabricated data as genuine, most commonly counterfeit GNSS signals reporting false position or time information.
Concept/Framework
State Estimation
State Estimation is the inference of a system's internal state from measured data, model behavior, or both. It estimates what cannot be directly observed.
Operations
State Synchronization
State synchronization is the process of ensuring that distributed components share a consistent view of operational state. It is used so failover, steering, and session handling continue to work when…
Concept/Framework
Stateless Communication
Stateless Communication is communication in which each message is handled independently without relying on stored session context.
Protocol
Store and Forward
A design pattern in which data is held locally at its point of origin when a network connection is unavailable, then transmitted once connectivity is restored, preserving data generated during…
Concept/Framework
Storm Avoidance Data Link
Storm Avoidance Data Link is the communications link used to transmit storm-avoidance advisories, forecasts, or route changes to Maritime operators. It supports safety-aware navigation and enables timely operational response to…
Protocol
Submarine Cable
A fiber-optic cable laid across an ocean or sea floor connecting continents or islands, using DWDM to maximize usable capacity per fiber pair, terminating at coastal landing stations that connect…
Hardware
Substation Automation
The use of intelligent electronic devices and digital communication within an electrical substation to monitor, protect, and control switching and protection equipment automatically, replacing manual switching and electromechanical protection relays…
Concept/Framework
Sun Sensor
Sun Sensor is an attitude sensor that determines spacecraft orientation by detecting the direction of the Sun and translating that measurement into an angular reference for the spacecraft.
