Why does this matter operationally?

Service Assurance

The operational discipline of guaranteeing that connectivity services meet defined performance levels, availability targets, and recovery time objectives. Service assurance combines monitoring, SLA management, and proactive intervention to maintain the reliability that industrial operations depend on.

ACARS A digital datalink protocol carrying short text messages and automated status reports between aircraft and ground systems — airline operations centers and air traffic control — over VHF, HF, or… Protocol Access Control Access control is the process of evaluating a subject’s identity, attributes, or context against policy to determine whether access to a resource should be granted, limited, or denied. It is… Concept/Framework Active-Active Duplication Active-active duplication is a high-availability design pattern in which multiple systems operate concurrently and provide the same or coordinated service. The duplicated components share workload and can continue service if… Concept/Framework Adjacent Channel Interference Adjacent channel interference is the degradation of a communication channel caused by energy from a nearby channel bleeding into the wanted signal path. Concept/Framework Admission Control Admission Control is the decision process that determines whether a new flow, call, session, or request is allowed to enter a network or service. It protects available capacity. Operations ADS-B A surveillance protocol under which an aircraft automatically and continuously broadcasts its GNSS-derived position, altitude, velocity, and identity for reception by ground stations and nearby aircraft, without requiring radar interrogation. Protocol ADS-C A surveillance protocol in which an aircraft's position and status reports are transmitted to air traffic control under an agreed contract defining reporting triggers, used primarily in oceanic and remote… Protocol AeroMACS A broadband wireless communications standard providing high-bandwidth connectivity between aircraft, ground vehicles, and airport systems specifically for airport surface operations, distinct from lower-bandwidth enroute datalink technologies. Protocol Aeronautical Telecommunication Network The ICAO-defined network-layer standard providing common addressing, routing, and application-support services across heterogeneous underlying aeronautical datalink media — VHF Data Link, satellite, and HF — enabling datalink applications to function… Concept/Framework Aggregation Aggregation is the process of consolidating multiple routes, addresses, or resources into one broader entity for management, advertisement, or control. In networking, it is commonly used to reduce routing complexity… Concept/Framework
