Network Topology Network topology is the structural arrangement of devices and connections in a network, either as actually built or as logically represented. It determines how traffic can travel and how the… Concept/Framework Observability Observability is the ability to infer the internal state of a system from its external outputs such as logs, metrics, and traces. 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 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 OSI Model OSI Model is a seven-layer conceptual framework that describes how network communication functions are organized from physical transmission to application services. Concept/Framework 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 Capture Packet Capture is the recording of network packets for analysis, troubleshooting, security review, or protocol inspection. It preserves traffic for examination. 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. Protocol Path Assurance Path Assurance is the effort to ensure that a communications or routing path remains available, valid, and fit for service. Operations
