Key Points – Marks failed routes as unusable – Used in distance-vector routing – Helps prevent routing loops – Supports faster recovery after topology changes Definition Route Poisoning is a routing technique that advertises a failed route with an invalid…
Key Points – Service Chaining is an ordered sequence of network or security services applied to traffic. – Traffic is steered through defined functions such as firewalls, optimizers, load balancers, or other network services. – Used in cloud networking, security…
Key Points Finds shortest paths from a source node to all other nodes Supports negative edge weights in graphs Detects negative cycles within the graph structure Used in graph analysis, routing research, and network optimization Higher computational cost than algorithms…
Key Points – Provides onboard internet and operational connectivity – Supports crew and business applications – Requires marine coverage and shipboard integration – Service quality depends on vessel motion, coverage, and onboard network architecture – Combines Maritime satellite access or…
Key Points Separates crew-facing traffic from operational vessel systems Reduces security and reliability risk to safety-critical functions Common in managed vessel networks Implemented through segmentation, filtering, and dedicated access paths Preserves operational safety while maintaining user connectivity Definition Crew Network…
Key Points Provides alternate path selection when the primary route fails or degrades Supports service continuity during outages or network degradation Common in resilient networks and satellite communications Triggered by outages, degradation, or policy constraints Requires detection mechanisms and backup…
Key Points – Process Dead Time is defined for network and system use – Represents delay before a process output begins to respond to an input change – Used in operational and control contexts – Makes control more difficult because…
Key Points Proportion of frames received with errors Measures frame-level reliability rather than bit-level reliability Used across wireless systems, satellite links, and digital transport Useful when link performance is evaluated in terms of whole frames that survive transmission intact Definition…
Key Points – First active stage for RF signal handling – Often includes filtering and amplification – Important for noise and selectivity – Operates at the start of the radio-frequency signal chain – Used in satellite terminals, radios, wireless systems,…
Key Points – Uses labels to forward traffic efficiently across networks – Commonly used in carrier and enterprise WAN environments – Supports traffic engineering and quality-of-service mechanisms – Often associated with managed WAN and VPN services – Can coexist with…
