Key Points Connects subscribers or sites to upstream network layers Supports wired or wireless last-mile access Operates as the entry point for connectivity control Interacts with transport, routing, and service layers Terminates local access links and applies authentication or access…
Key Points Delivers routing data based on weather conditions Supports navigation and voyage planning Relies on timely and accurate environmental data Timely delivery is critical because route decisions depend on current conditions Definition Weather Routing Data Delivery is the transport…
Key Points Time-series storage for operational and process history Continuously collects and stores operational data for later retrieval and analysis Used in industrial automation, control systems, utilities, and operations centers Supports understanding how industrial systems behaved and changed over time…
Key Points Control method without output feedback correction Applied in contexts where the process is predictable enough that fixed input is acceptable Used in simple automation, timed operations, and systems where feedback is unavailable or unnecessary Simpler than feedback control…
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 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…
