Key Points One-to-many-to-selected-receivers model Used in streaming and network distribution More efficient than multiple unicast copies Requires group membership or subscription Differs from broadcast by limiting to subscribed receivers only Differs from unicast by eliminating per-receiver sender replication Definition Multicast…
Key Points Improves data integrity and reliability Used in communication and storage systems Can recover from some corruption without retransmission Often paired with error detection Adds encoding overhead and processing cost Maximum correctable error rates are code-dependent Definition Error Correction…
Key Points Manages power on the transmit side of a downlink Supports coverage and interference balancing Used in cellular and satellite systems Can react to traffic load or channel conditions Can be fixed or dynamically adjusted based on link conditions…
Key Points Tracks system settings and versions Supports consistency and repeatability Used in IT, cloud, and operations Important for change control and auditability Ensures deployed systems match intended state Definition Configuration Management is the process of defining, tracking, and controlling…
Key Points Continuous or periodic operational data flow Used for monitoring and control Common in satellite, cloud, and industrial systems Provides visibility into state, health, and behavior Can be consumed live for alarms, dashboards, or historical storage Definition Telemetry Stream…
Key Points Path Computation calculates a network path from topology and constraints Used in operational and architecture contexts for routing decisions Optimizes for latency, resilience, capacity, or policy compliance Operates within carrier networks, transport systems, and segment-routing environments Depends on…
Key Points Fault Tolerance is the ability to continue operation despite faults or failures Relies on redundancy, error handling, and recovery logic Used in cloud systems, networking, industrial control, and critical infrastructure Involves tradeoffs between resilience, cost, and architectural complexity…
Key Points Midhaul Transport is the transport layer between access or radio elements and aggregation or core infrastructure It carries traffic between distributed access sites and central network nodes Used in mobile networks, distributed radio systems, and telecom transport architectures…
Key Points Supports fleet coordination and safety across coastal and offshore operations Often operates in remote or coastal waters with coverage gaps Must balance cost sensitivity, equipment durability, and reliable service delivery Operates in harsh marine environments with motion, weather,…
Key Points Used to recover from transmission errors Common in network and link protocols Can improve reliability at the cost of delay Relevant in transport, wireless, and storage systems Core part of error recovery and service robustness Definition Retransmission is…
