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 Supports offshore vessel operations Often needs coverage across open water and near shore Can include operational and crew connectivity Combines shipboard radios, satellite links, data services, and operational procedures Operates beyond terrestrial coverage reach Definition Offshore Support Vessel…
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 Approximately fixed over one longitude Used for communications, broadcasting, weather, and observation services Provides wide regional coverage with simple user pointing Has higher latency than lower orbits Requires station-keeping maneuvers to maintain position Benefits from stable, continuous viewing…
Key Points Finds shortest path from a source node to all reachable destinations Uses cumulative path cost to expand candidates Applies to routing, path planning, network engineering, and graph optimization problems Requires nonnegative edge weights Produces deterministic, globally optimal paths…
Key Points Software-based deployment model for network functions Replaces or supplements fixed-purpose network appliances with virtualized software functions Functions such as routing, firewalling, and optimization run on virtualized infrastructure Enables flexible deployment, scaling, and orchestration of network capabilities Used in…
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…
Key Points Shares route metrics with neighboring routers Uses hop count as its primary metric Simple routing protocol with limited scale Used mainly in legacy or small networks Limited ability to model complex topologies Slower convergence compared to more advanced…
Key Points Timing requirement where occasional misses degrade quality rather than cause failure Defined for network or system use in operational and control contexts Used in media, interactive systems, and latency-sensitive control applications Tolerates occasional misses while maintaining acceptable service…
Key Points Delivered as a network service over cloud infrastructure Can include file, block, or object storage models Used for applications, backups, archives, and enterprise workloads Scales with cloud infrastructure without local hardware ownership Access performance, retention cost, consistency behavior,…
