Key Points Handles packet movement through the device Operates based on routing or switching decisions Distinct from the control plane Found in routers, switches, and firewalls Execution layer of packet transport in network devices Depends on accurate forwarding state from…
Key Points Contrasts access connectivity with transport connectivity Useful for network architecture discussion Access serves endpoints; backhaul links access to core Common in telecom planning and design Separates service delivery roles in distributed network architectures Definition Backhaul Vs Access is…
Key Points Uses multiple satellite-to-satellite paths Supports distributed routing and resilience Common in constellations and advanced space networks Can reduce dependence on a single relay path Definition Mesh Satellite Network is a satellite architecture in which satellites are interconnected through…
Key Points Lower microwave frequency range Offers good propagation and penetration characteristics Used in mobile and satellite applications Supports robust links with relatively large antennas or lower bandwidths Strong cross-industry relevance across telecom, Aviation, Maritime, and satellite systems Definition L…
Key Points Defines permitted delay across a path Used in service and network design Often divided across multiple hops or segments Supports performance planning for real-time services Operationally meaningful in voice, video, trading, industrial control, and satellite services Definition Latency…
Key Points Distributes traffic across servers or services Improves resilience and capacity usage Used in network and application architectures Can operate at multiple layers Prevents single points of failure and bottlenecks Definition A Load Balancer is a system that distributes…
Key Points Connects spacecraft directly in space for orbital data exchange Supports routing, relay, and coordination between satellites Reduces reliance on ground relay in constellation and relay architectures Used in satellite constellations, Earth observation systems, navigation systems, and space-based communications…
Key Points Provides multiple available routes Improves resilience and availability Used in networks and transport systems Reduces dependence on a single path Most valuable when alternate paths do not share the same failure domain Definition Path Diversity is the presence…
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 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…
