Key Points Stores consumable propellant for propulsion hardware Maintains pressure and containment during storage and feed Supplies thrusters and propulsion systems on command Subject to thermal, structural, and contamination constraints Failure modes include leakage, pressure loss, contamination, and feed blockage…
Key Points Reduces overload in shared networks Used in transport and routing systems Supports stable throughput and fairness Often works with retransmission and flow control Adjusts sending rates, manages queues, or influences traffic patterns to maintain useful throughput Prevents excessive…
Key Points Describes the access segment nearest the user Often a major determinant of service quality Can be wired or wireless Common in broadband and service delivery discussions Frequently the limiting factor in end-user service quality even when the core…
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 Process Variable is the measured value used by a control system It exists to represent the current state of the process relative to a target The process variable is compared with a setpoint to determine control action Used…
Key Points Describes shared-capacity oversubscription Used in access and broadband planning Higher ratios mean more sharing Common in telecom service design Indicates expected resource sharing relative to committed capacity Definition Contention Ratio is the ratio between the total capacity shared…
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 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 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…
