Key Points Relates routing to Maritime jurisdiction Can affect where traffic or service is permitted Combines network planning with regulatory constraints Definition Exclusive Economic Zone Routing is routing or service planning that accounts for Maritime jurisdiction boundaries and regulatory conditions…
Key Points Supports offshore vessel operations Often needs coverage across open water and near shore Can include operational and crew connectivity Combines shipboard radios, satellite links, data services, and operational procedures Operates beyond terrestrial coverage reach Definition Offshore Support Vessel…
Key Points Administrative access over the production network path No separate management network required Used in operational and architecture contexts Depends on availability of the production path Simplicity versus isolation tradeoff Definition In-Band Management is administrative access to a system…
Key Points Approximately fixed over one longitude Used for communications, broadcasting, weather, and observation services Provides wide regional coverage with simple user pointing Has higher latency than lower orbits Requires station-keeping maneuvers to maintain position Benefits from stable, continuous viewing…
Key Points Buffers messages between systems Supports asynchronous processing Common in distributed architectures Helps decouple producers and consumers Absorbs bursts and smooths workload differences Improves resilience through loose coupling Definition Message Queue is an asynchronous messaging system that stores messages…
Key Points Detects or resists false timing inputs Supports secure synchronization Important where timing affects control or navigation Validates timing sources and compares multiple references Rejects inconsistent or suspicious timing inputs Definition Anti Spoof Timing is timing protection that detects…
Key Points Control method that acts before error grows large Responds to input conditions or disturbances in advance Often combined with feedback control for better performance Used in industrial automation, process control, and systems with known disturbances Definition Feedforward Control…
Key Points Shares route metrics with neighboring routers Uses hop count as its primary metric Simple routing protocol with limited scale Used mainly in legacy or small networks Limited ability to model complex topologies Slower convergence compared to more advanced…
Key Points Uses proportional, integral, and derivative terms Common in industrial control Helps regulate process variables Requires tuning for stability and response One of the most common closed-loop control strategies Definition PID Controller is a feedback controller that uses proportional,…
Key Points Lower microwave band with strong propagation characteristics Known for weather resilience compared to higher microwave bands Used in satellite communications, broadcasting, and fixed wireless systems Moderate bandwidth capacity with robust coverage Often selected where stability and reliability are…
