Why does this matter operationally?
Performance
The measurable behaviour of a connectivity system under real operating conditions, including throughput, latency, jitter, and packet loss. Performance determines whether applications and control systems receive data at the speed and consistency their operations require.

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
Orbital Plane
Orbital Plane is the geometric plane in which a spacecraft or satellite orbit lies around its central body. It defines the orientation of the orbit in space.
Concept/Framework
Orbital Slot
Orbital Slot is a designated orbital position assigned to a satellite or spacecraft for operational coordination and service planning.

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
OSPFv3
OSPFv3 is the IPv6 version of the OSPF link-state routing protocol used to exchange routing information within an autonomous system. It supports IPv6 routing domains.
Protocol
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.
