Key Points Communication model where each message is independent of prior messages Each request is self-contained and carries all necessary information Simplifies scaling, recovery, and interoperability Reduces dependency on stored connection state Used in web services, APIs, distributed systems, and…
Key Points Supports communication during disruptions and emergencies Used in public safety, disaster recovery, and critical infrastructure scenarios May rely on backup paths, satellite links, mobile fallback, or rapidly deployable systems Prioritizes continuity and reachability over standard service Operates across…
Key Points Provides alternate paths or components Used to improve availability and resilience Can be active-active or active-standby Applied in networks, control systems, and infrastructure Requires deliberate planning for failure domains Common forms include duplicated hardware, alternate links, and failover…
Key Points Alarm Flood Suppression filters large alarm bursts to reduce operator overload Used in operational and control contexts to improve operator focus Suppresses redundant, cascading, or lower-value alarms while maintaining visibility of critical alarms Primary application in industrial automation,…
Key Points Transfers an active session between service points Used in mobile, satellite, and wireless systems Supports continuity during movement or reallocation Can be triggered by coverage or load changes Constraints include timing, signal quality, session continuity, and coordination between…
Key Points Orbit higher than LEO and lower than GEO Used in navigation and some communications systems Has intermediate latency and coverage characteristics Requires orbital planning and constellation design Offers a different balance of latency, coverage, and constellation size compared…
Key Points Delivers weather hazard information to vessels in real time Supports route changes and safety-critical navigation decisions Must remain available during adverse conditions Enables timely hazard avoidance before vessels reach dangerous areas Critical for Maritime safety and voyage planning…
Key Points Provides precise attitude knowledge Uses star patterns as an inertial reference Common in high-accuracy spacecraft control Works by imaging the sky and matching detected star patterns to an internal catalog Often paired with attitude actuators to close the…
Key Points Observer Model infers hidden state from system observations Used in operational and control contexts Commonly applied in control engineering, robotics, and signal processing Works by using a representation of system behavior to infer hidden variables that cannot be…
Key Points Uses fixed-size cells for transport Supports circuit-like and packet-like services Historically used in carrier and broadband networks Requires specialized switching and segmentation Carries traffic in fixed-size cells across a packetized infrastructure Separates payload into small cells for uniform…
