Key Points – Operates in low Earth orbit – Commonly deployed as part of a constellation – Supports lower latency than higher orbit systems – Requires continuous handoff and tracking due to orbital movement – Used in communications, observation, and…
Key Points – Service Degradation represents reduced service performance without full outage – Defined for network and system contexts – Used in operational and architecture monitoring – Distinguishes partial impairment from complete service failure Definition Service Degradation is a reduction…
Key Points – Designed for rapid failure recovery – Uses preplanned alternate paths or local repair mechanisms – Common in carrier and IP backbones – Reduces disruption during link or node failures – Enables sub-second or near-instant protection against failures…
Key Points – Traffic Mirroring duplicates packets or flows to a mirrored output while leaving the primary traffic path in place – Used for observability and traffic analysis in live networks without forcing the monitoring system into the data path…
Key Points – Data Plane is the operational execution layer that moves traffic or processes data after control decisions are made – It is separate from the control plane, which makes policy decisions – Used in routers, switches, firewalls, and…
Key Points – Shares channels or links across multiple users or services – Used in telecom, radio systems, and transport networks – Improves utilization of limited resources through pooling – Relies on dynamic allocation or pooling mechanisms – Enables efficient…
Key Points – Raises signal frequency to a higher band – Common in transmit chains – Often paired with a local oscillator – Works by mixing input signal with local oscillator to move output to higher target band – Used…
Key Points – Connection State is defined for network or system use. – Stored information about an active or observed connection. – Used across network and system environments. – Used in firewalls, load balancers, servers, and network services. – Helps…
Key Points – Consolidates multiple inputs into fewer outputs – Reduces upstream traffic or simplifies reporting – Common in Edge Compute and monitoring architectures – Sits between local sources and central storage or analytics systems – Used in Edge Compute…
Key Points – Mixes multiple network types or models – Used in enterprise and telecom environments – Can combine public and private resources – Requires integration and policy management – Blends connectivity across different network boundaries Definition Hybrid Network is…
