Key Points Tracks flow across system boundaries Used in observability and debugging Supports latency and dependency analysis Common in distributed systems Reveals dependencies between services and components Identifies where time is spent in transactions Definition Tracing is the recording or…
Key Points State Estimation is defined for network or system use. Inference of hidden or internal system state from available data. Used in operational and control contexts. Works by combining observations with a model to estimate values that are not…
Key Points Reduces dependence on a single supplier Uses standardized or portable interfaces Common in multi-vendor operational environments Enables systems from different vendors to exchange data or functions Reduces lock-in and makes mixed environments easier to operate Definition Vendor-Agnostic Integration…
Key Points Demultiplexing is the separation of combined data or signal streams into their component parts Used across network and system contexts for restoring individual flows Works by using identifiers, timing, encoding, or channel structure to split combined streams Operates…
Key Points Maintains orbital position and geometry over time Uses scheduled or on-demand maneuvers to counter drift and perturbations Relies on periodic corrections and control planning Essential for preserving satellite service continuity and mission effectiveness Constrained by propellant budget, maneuver…
Key Points Industrial communication protocol for automation and field device connectivity Operates at the field-level communication layer in industrial systems Used in manufacturing, process systems, and installed industrial networks Many existing industrial installations continue to depend on Profibus Constraints include…
Key Points Transmission using a shared timing reference Sender and receiver coordinate via common clock or timing relationship Used in networking, telecom systems, serial links, and digital communications Requires timing accuracy and clock distribution Framing and timing consistency enable reliable…
Key Points Connects different networks or domains May translate protocols or addresses Used in telecom, cloud, and industrial systems Can be physical or logical Acts as a boundary element between separate communication domains Definition Gateway is a device, node, or…
Key Points Acts as a front door for API traffic Can apply auth, routing, and transformation rules Simplifies client access to multiple backend services Used in distributed application architectures Provides a managed entry point for application traffic Centralizes authentication, authorization,…
Key Points Enforces one-way data movement between domains Used to separate trusted and less trusted security domains Common in critical infrastructure and industrial security environments Prevents reverse flow of data across security boundaries Operates as a hardware or logical enforcement…
