Key Points Operates between autonomous systems Used for inter-domain routing Supports internet-scale route exchange Relies on policy as well as reachability Enables policy-based route control across administrative boundaries Used by service providers, enterprises with external connectivity, and networks that exchange…
Key Points Links access sites to aggregation or core network Used in telecom and enterprise transport architectures Carries aggregated traffic from remote or edge compute sites Can be implemented using fiber, microwave, satellite, or leased line media Critical dependency for…
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 Transfers data between separated satcom security domains Applies filtering and policy controls at domain boundaries Used where satellite links cross trust boundaries Operates in protected satellite networks, Government & Defence systems, and regulated environments Enables information exchange across…
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 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 Stateful Inspection evaluates traffic based on connection or session context rather than isolated packets Used in firewalls, gateways, and network security appliances Improves control by understanding whether traffic belongs to an allowed relationship Operates at the Transport layer…
Key Points Combines multiple orbital regimes (LEO, MEO, GEO) Improves coverage and service flexibility by leveraging different orbit characteristics Used in advanced satellite networks and global communications systems Requires coordination and routing across orbit layers Integrates lower-latency lower orbit systems…
Key Points Connects unmanned surface vessels to remote operators and support systems Supports command, telemetry, and mission data transmission Operates in challenging maritime conditions with variable sea state, coverage gaps, and latency constraints Link design must account for motion, range…
Key Points Measures signal strength relative to noise Used to judge link quality Common in satellite and RF systems Determines whether a link can support the intended modulation and coding Link performance is limited by how much useful carrier power…
