Key Technologies and Challenges of Satellite Deterministic Network

Abstract

Satellite internet is an important means to meet the ubiquitous network access in the future.It has a wide range of application scenarios in disaster prevention, marine operation and scientific research broadband on account of its wide coverage, large communication capacity and global seamless connection.Started from the vision of the deterministic transmission of satellite internet, combined with the existing deterministic network technology, the satellite deterministic network architecture was put forward, and the existing challenges and future development in deterministic access, multi-service differentiation guarantee, dynamic resource allocation and path backup of satellite deterministic network were pointed out.
