Key Points Uses direct node-to-node links instead of hub-based paths Reduces dependency on ground or central hub paths Common in mesh and multi-node satellite networks Improves path flexibility and resilience in distributed transport systems Requires topology awareness and dynamic link…
Key Points Centralized network monitoring and response Tracks alarms, performance, and incidents Coordinates troubleshooting, escalation, and service continuity Primary use in telecom and service operations Definition Network Operations Center is the operational facility that monitors, manages, and responds to events…
Key Points Software-based implementation of a network function Deployed on virtualized or cloud infrastructure instead of dedicated hardware Allows functions such as routing, firewalling, or optimization to be delivered in software form Enables flexible deployment, scaling, and management of network…
Key Points Uses satellite links as part of mobile access Targets standard or near-standard cellular devices Extends coverage beyond terrestrial network reach Requires coordination between space and mobile infrastructure Depends on coordination between space segment resources, mobile network integration, and…
Key Points Maintains operation after faults instead of immediate shutdown May continue in degraded mode with reduced capability Common in safety-critical and control applications Depends on redundancy, fallback modes, and fault isolation Preferred or required in industrial systems and resilient…
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 Orbit very close to Earth Can support lower latency and high-resolution sensing Faces strong atmospheric drag and operational constraints Used in specialized communication and observation systems Subject to higher control burden and mission complexity Requires robust attitude and…
Key Points Provides command functions on the move Supports distributed operations and coordination Used in field and emergency scenarios Integrates terminals, routing, and local decision support Enables operations outside fixed command sites Definition Mobile Command Node is a movable command…
Key Points Traffic Engineering involves deliberate planning and control of traffic flow to meet network objectives Used to balance load, protect services, and control latency across network environments Operates through metrics, policy, or explicit path selection to steer flows intentionally…
Key Points Service Level Objective is defined for network or system use Target performance or reliability level for a service Used in operational and architecture contexts Turns service expectations into measurable thresholds such as availability, latency, or error rate Helps…
