Observability Observability is the ability to infer the internal state of a system from its external outputs such as logs, metrics, and traces. Software Observer Model Observer Model is a mathematical or computational model used to estimate internal system states from available inputs and outputs. Software Onboard Networking Onboard networking is the set of internal network connections and control functions that distribute data among systems on a platform such as an aircraft. It links sensors, payloads, processing systems,… Concept/Framework Orbit Orbit is the trajectory followed by an object under the influence of gravity and its own velocity, typically around a planet, moon, or other celestial body. In operational practice, the… Concept/Framework Origin Server An origin server is the primary server or service endpoint that stores and serves the canonical version of content or application responses. Other systems, such as caches or proxies, may… Hardware Oscillator An oscillator is an electronic circuit or device that produces a periodic signal at a target frequency without requiring an external periodic input. It is used as a frequency reference… Hardware Out Of Band Management Out Of Band Management is administrative access to a system through a separate management path that is independent of the primary production traffic path. It preserves control when the main… Operations Oversubscription Oversubscription is the practice of allocating more potential demand than the guaranteed capacity of a shared resource, based on the assumption that not all users or workloads will peak simultaneously. Operations Packet Loss Packet Loss is the failure of one or more packets to reach their destination across a communication network. It reduces reliability and can degrade service quality. Protocol Packet Switching Packet Switching is a communication method in which data is divided into packets that are transmitted independently across a network, enabling flexible routing and shared network infrastructure use.
