Key Points First-Mile Access is the access segment between the user and the provider network Defined for network and system use in operational and architecture contexts Can include wired, wireless, or satellite access depending on the service model User experience…
Key Points Traffic Mirroring duplicates packets or flows to a mirrored output while leaving the primary traffic path in place Used for observability and traffic analysis in live networks without forcing the monitoring system into the data path Common in…
Key Points Consolidates multiple inputs into fewer outputs Reduces upstream traffic or simplifies reporting Common in Edge Compute and monitoring architectures Sits between local sources and central storage or analytics systems Used in Edge Compute architectures, monitoring systems, industrial networks,…
Key Points Supports field operations and mobility Often hardened for harsh conditions Emphasizes ruggedness, portability, and secure connectivity Used in Government & Defence communications, expeditionary operations, and field deployments Operates as a portable endpoint without relying on fixed infrastructure Definition…
Key Points Provides relay capability from the air Extends coverage over terrain or distance Used in emergency and expeditionary operations Operates via placement of a relay node at altitude for line-of-sight forwarding Constraints include endurance, payload limits, weather, altitude, and…
Key Points Manages orientation rather than position Uses sensors and actuators for correction Important for pointing antennas, solar panels, and instruments Core function in spacecraft and flight systems Relies on measurement, control logic, and actuation to hold or change orientation…
Key Points Blocks unsafe sequences or commands Depends on condition checks before action Common in machinery and process protection Reduces risk of unsafe start, sequencing, or operation Works by enforcing prerequisite conditions Definition Interlock System is a safety or control…
Key Points Uses outputs to understand internal state Common in operations and software systems Depends on metrics, logs, and traces Supports troubleshooting and analysis Enables operators and tools to reconstruct behavior and identify anomalies Definition Observability is the ability to…
Key Points Includes hardware for thrust generation, propellant tanks, valves, thrusters, and feed lines Manages propellant flow and maneuvering through coordinated control logic Supports orbit and attitude control functions Essential for trajectory maintenance and changes in spacecraft operations Definition Propulsion…
Key Points Depends on distance and medium velocity Affects latency in communication and control systems Important in wired, wireless, and satellite links Can limit timing performance and synchronization Sets an unavoidable lower bound on how quickly information can move between…
