Key Points Carries RF energy with controlled loss Includes flanges, bends, and joints Used in satellite and microwave systems Connects amplifiers, converters, and antenna feeds Constrains include insertion loss, alignment, mechanical fit, pressure or environmental sealing Failure modes include leakage,…
Key Points Describes field orientation of electromagnetic waves Used in RF and antenna design Important for interference separation and spectrum reuse May be linear, circular, or other forms Affects channel separation, propagation, and spectrum reuse capability Definition Polarization is the…
Key Points Uses application context in routing decisions Supports policy-based traffic steering Common in enterprise and cloud networks Can optimize service performance by flow type Works by using classification, metadata, policy rules, or telemetry to direct specific traffic to preferred…
Key Points Mounted on the vessel deck or superstructure Supports shipboard connectivity and communications at sea Must handle vessel motion, weather conditions, and corrosive salt spray environment Performance depends on placement position and deck space availability Physical mounting position often…
Key Points Controlled reduction in capability while preserving partial operation Preserves partial function rather than failing completely Used in operational and architecture contexts Works by shedding optional functions, reducing quality, or disabling nonessential features in a planned way Definition Graceful…
Key Points Route Convergence is the process of reaching consistent routing state after topology change Routers exchange updates, recalculate routes, and settle on stable forwarding state Route convergence speed is often a major operational concern because users may experience loss…
Key Points Operational data collection from network systems including routers, switches, gateways, and cloud network services Produces metrics, events, traces, and measurements that describe network behavior over time Supports monitoring, troubleshooting, and performance analysis Enables visibility into traffic, device health,…
Key Points Provides isolated compute instance running on virtualization infrastructure Runs on a host through hypervisor software Common in cloud and enterprise systems Supports workload portability and consolidation Enables efficient hardware resource sharing Requires management of virtualization overhead and image…
Key Points Traffic Shaping paces traffic to match a target rate or profile Works by delaying or scheduling packets to release traffic in controlled patterns instead of uncontrolled bursts Used in routers, carrier networks, access links, and service policy systems…
Key Points Defines how information is placed on a carrier wave Affects bandwidth, robustness, and throughput Used in radio, wireless, satellite, and digital communication systems Often paired with coding and link adaptation Different schemes suit different channel conditions and service…
