Abstract

Abstract:

As the Internet evolves from a consumer network to a productive network, emerging industry applications necessitate differentiated and deterministic service quality assurance and communication capabilities that span all dimensions of time and space.How to realize the heterogeneous compatibility of ubiquitous multi-domain networks and support deterministic transmission between nodes in space-air-ground integrated network (SAGIN) has become a significant research problem.Firstly, the emerging full-domain 6G scenarios along with their requirements for deterministic services were analyzed.Then, the hierarchical space-air-ground integrated deterministic networking architecture, including global cooperative network management and control layer, multi-domain dynamic deterministic fusion layer, and ubiquitous heterogeneous deterministic networking layer, was proposed, and key technologies for fixed-mobile-satellite fusion networks in relevant scenarios were studied.Finally, the challenges and development trend of the space-air-ground integrated deterministic networking were presented.

Key words: space-air-ground integrated network, network architecture, deterministic networking, 6G
