Standardisation Assessment of a Digital Twin-Based Multi-Domain Deterministic Communications System

Many service flows between client and server end-points traverse multiple computer networks even for a private network deployment. The challenge of reducing the complexity of such services is researched on by the European Commission-funded project PREDICT-6G, with special focus on deterministic communications. The provisioning of service flows over a multi-domain multi-technology group of computer networks is a particular challenge if each domain comes with its own set of deterministic communication support. To address that, an overarching End-to-End control plane is being developed in the project and is described herein. As the proposed innovations require a mix of technologies from Standardisation Development Organisations, this paper assesses the proposition of PREDICT-6G against the ongoing work in 3GPP, IETF, ETSI and IEEE.
