Key Points Describes service performance characteristics in measurable terms Can be implemented through policy or network controls such as queueing, classification, shaping, or admission controls Often measured alongside latency and reliability Used in communication and service design across enterprise networking,…
Key Points Uses a central hub for interconnection Simplifies routing and control Common in telecom and enterprise designs Can create a central dependency Hub capacity and resilience become critical factors Definition Hub And Spoke Architecture is a network design in…
Key Points Measures delay in a communication or processing path Includes propagation, queueing, and processing components Important for real-time and interactive services Often evaluated alongside jitter and throughput Aggregate measure that can span multiple system layers depending on context Definition…
Key Points Ground site for satellite communications and gateway operations Houses antennas and supporting communications equipment Enables uplink and downlink functions Part of the ground segment infrastructure Core facility in satellite systems, broadcast distribution, and gateway operations Subject to constraints…
Key Points Creates a dedicated communication path Traditionally used in telephony Reserves resources for the session duration Differs from packet switching Definition Circuit Switching is a communication method that establishes a dedicated path between endpoints for the duration of a…
Key Points Uses more than one equal-cost route Can improve utilization and redundancy Common in routed IP networks Often used with load sharing or multipath forwarding Distributes traffic across paths according to a hashing or load-sharing strategy Used in data…
Key Points IBGP is a communication protocol for internal BGP routing sessions within a single autonomous system Used in service provider networks, enterprise routed networks, and large internal routing designs Supports route propagation and internal consistency without crossing administrative boundaries…
Key Points Describes layered internet protocol behavior Includes transport and internet functions Foundation of IP networking Used in nearly all modern networks Organizes communication into layers so each layer handles its own part of the process Definition TCP-IP Stack is…
Key Points Large-scale NAT deployed by service providers for address sharing Translates many subscriber connections through a shared pool of public addresses and ports Reduces address scarcity pressure but increases state and operational complexity Used by internet service providers and…
Key Points Source-routing method using ordered forwarding instructions Encodes path behavior as segments so routers can follow intended forwarding instructions Eliminates need for each hop to maintain separate complex path state Simplifies traffic steering and path control Used in service…
