Key Points Protects payload content from unauthorized reading Used in secure communications and transport Often paired with key management and access control Combines data transport with information security Used in satcom, secure networking, and protected data transport Encryption helps preserve…
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 Divides data into packets that can be routed independently Packets can take different paths through the network Foundation of IP networking and modern digital communications More flexible and scalable than dedicated circuit switching Enables shared infrastructure to carry…
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 access layer to core or aggregation infrastructure Carries aggregated traffic from Edge Compute sites and access points Used in mobile networks, broadband systems, enterprise connectivity, and remote service architectures May use fiber, microwave, satellite, or other transport…
Key Points Holdover Timing is defined for network or system use Timing continuity when an external reference is lost Used across network and system environments Holdover quality depends on oscillator stability and the duration of reference loss Cross-industry relevance is…
Key Points Error-control method using redundant coding for receiver-side correction Works by encoding data with additional parity or check information Allows receiver to reconstruct missing or corrupted bits without retransmission Used in satellite communications, wireless systems, broadcast transport, and other…
Key Points Allocates shared capacity above guaranteed baseline Common in networks and cloud systems Relies on statistical concurrency assumptions Can improve utilization and reduce costs but increases congestion risk Deliberate capacity strategy that trades guaranteed headroom for higher utilization Failure…
Key Points Administrative access over the production network path No separate management network required Used in operational and architecture contexts Depends on availability of the production path Simplicity versus isolation tradeoff Definition In-Band Management is administrative access to a system…
Key Points Uses passive or minimal processing relay mechanism Common in traditional satellite links and broadcast systems Depends heavily on ground segment for signal processing Contrasts with regenerative payload designs Reduces spacecraft complexity at the cost of onboard flexibility Amplifies…
