Recommendation ITU-T Y.3167 specifies quality of service requirements and framework for supporting deterministic communication services in large scale networks for IMT-2020 and beyond. It enables a delivery of the deterministic services that guarantee the bounded latency, jitter and packet loss rate for the scale of a telecommunication operator’s network. It also provides the use cases in Appendix Ⅰ, the problem analysis of data plane in Appendix Ⅱ, and the experiment data in Appendix Ⅲ.
