China Mobile Huawei Futurewei Technologies USA ZTE Corporation ETRI New H3C Technologies Huawei Aiming at scaling deterministic networks, this document describes the technical and operational requirements when the network has large variation in latency among hops, great number of flows and/or multiple domains without the same time source. Different deterministic levels of applications co-exist and are transported in such a network. This document also describes the corresponding Deterministic Networking (DetNet) data plane enhancement requirements.
