摘要

Classical networks treat every bit as equally important, which wastes time and energy in factories and requires extra traffic engineering for critical traffic. Semantic communications send only what a task needs, but how can they be tested under realistic conditions? This paper examines what can be tested today in 6G industrial IoT, that is, networks of factory machines, robots, and sensors, and what is still missing. It introduces semantic importance, a score attached to each message that states how much the message matters, and uses it in a context-driven design to derive eight testing needs. Existing simulators, emulators, testbeds, codecs, and learning frameworks are assessed against these needs, which reveals five gaps. We propose a toolchain of four components built around the ns-3 simulator for simulated and emulated scenarios.
