Key Points Provide numerical evidence for state or performance Used in monitoring and analysis Can describe technical or business behavior Important in operations and assurance Enable data-driven operational decisions rather than assumption-based decisions Require careful selection to avoid measuring the…
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…
Key Points Represents IP network prefixes Used in IPv4 and IPv6 addressing Supports subnet planning and routing Compact alternative to older mask notation Definition CIDR Notation is a compact way to represent IP address prefixes and network masks using a…
Key Points Causes attenuation in RF propagation Depends on frequency and atmospheric composition Relevant in satellite and microwave links Can reduce link margin and coverage Frequency-dependent absorption peaks (oxygen and water vapor) Increases with path length and atmospheric density Distinct…
Key Points Handles service communication policies Supports traffic control and security Used in microservices and cloud-native environments Adds observability to east-west traffic Enforces mTLS, routing, and telemetry policies across service communication paths Definition Service Mesh is an infrastructure layer that…
Key Points Central hub connects many endpoints Reduces direct interconnection complexity Common in networking and logistics Creates a central dependency Hub capacity and latency are key constraints Single point of failure risk if hub redundancy is not designed Definition Hub…
Key Points Targets remote or sparsely populated areas Often uses mixed access technologies including fiber, fixed wireless, or satellite Important for digital inclusion and service reach Used in regional access planning, fixed wireless deployment, fiber expansion, and satellite-enabled service models…
Key Points Collision Domain defines the scope where transmissions can collide on a shared medium Exists to describe contention on Layer 1 or Layer 2 links Primary relevance in Ethernet history, shared media design, and network segmentation Matters most when…
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…
