Key Points Serves multiple users or services simultaneously Shares access capacity across a common terminal Used in access and satellite environments Requires capacity sharing, traffic controls, and access scheduling Lower hardware cost offset by increased contention and traffic management complexity…
Key Points Carries traffic in the forward direction from infrastructure to endpoint Important in satellite and access networks Often called the downlink from network to user perspective Service delivery often depends on robust forward link performance Operates across satellite communications,…
Key Points Operates inside a routing domain Supports internal path selection and convergence Used by routers to share network reachability Includes distance-vector and link-state families Definition An Interior Gateway Protocol is a routing protocol used to exchange reachability information within…
Key Points Reflects directional concentration of energy Affects transmit and receive performance Important in link budgets and coverage planning Influenced by design, size, and frequency Operates through antenna geometry and radiation pattern shaping Definition Antenna Gain is a measure of…
Key Points Affects antenna gain and beamwidth Important in satellite and wireless link budgets Influences installation and pointing requirements Balances performance against physical constraints Larger dishes generally improve gain but increase physical and installation requirements Definition Dish Size is the…
Key Points Stores values with timestamps or ordered time context Supports history, trend analysis, and reporting Common in operational and monitoring systems Organized around time to enable efficient writes and chronological query patterns Used in monitoring systems, industrial historians, observability…
Key Points Arises from shared channel use Common in wireless and satellite systems Can reduce capacity and quality Managed through reuse planning and coordination Central concern in spectrum reuse and coordination Definition Co Channel Interference is interference that occurs when…
Key Points Reduces repeated network transfers Improves access during limited connectivity Supports software, media, documentation, and operational reference data Enables local reuse of data in bandwidth-constrained maritime environments Balances local performance against data freshness and storage capacity Definition Content Caching…
Key Points Maps many internal hosts to one external address Uses port numbers to distinguish sessions Common in home and enterprise gateways Extends basic NAT behavior Shares limited public address space across multiple private endpoints Maintains translation state to associate…
Key Points One-to-many communication model Used in radio, TV, and data distribution Optimized for shared delivery rather than interactivity Common in satellite and terrestrial distribution Definition Broadcast Service is a communication service that sends the same content from one source…
