Real-World Node

Go up to Terms and Definitions

A Node may represent an actual operational system or may be represented through a virtual, simulated, emulated, or other realization used for testing.

A Real-World Node identifies the actual Node, system, device, service, or environment that exists outside the representation used by a test or simulation.

The term does not require the Node to be implemented solely using physical hardware. A real-world operational Node may itself use virtual machines, containers, cloud services, software-defined infrastructure, or other implementation technologies.

A Twin Realization may represent, observe, interact with, or otherwise correspond to a Real-World Node.

a Node realized by the actual system, device, service, or environment represented or exercised during testing

Derived from DIDO-TE source material distinguishing virtual Twin Nodes and real-world or physical Nodes participating in distributed testing.

“Real-world” distinguishes the actual participating or represented Node from a virtual, simulated, emulated, or other test representation. It does not imply that every component of the Node is implemented directly in physical hardware.

A production service operating in a remote facility may participate in a Test Environment as a Real-World Node while a Twin Realization represents that service within another portion of the test.
