摘要
卫星通信是未来通信领域的关键技术，低轨互联网星座是6G空天地海一体化网络的战略性基础设施，能够将当前通信网络扩展到全球近地区域。确定性网络技术是天基网络的重要技术之一，相比传统尽力而为的分组网络，确定性网络具有低时延、低抖动、低丢包率、高可靠的优势。概述了确定性网络当前的研究背景及现状，提出面向卫星通信的确定性网络架构，阐述了其关键技术，最后讨论了未来研究方向。
Abstract
Satellite communication is a critical technology in the future of the communication field.Low earth orbit Internet constellations is a strategic infrastructure for the 6G integrated space-air-ground-maritime networks
which is capable of expanding the current communication network to the global near-earth region.Deterministic networking technology is a key component of space-based network
compared with the traditional best-effort packet network
it has the advantages of low latency
low jitter
low packet loss rate
and high reliability.Firstly
the current research background and status of deterministic networking were summarized
and then a deterministic networking architecture for satellite communications was proposed and its key technologies were described.Finally
the outlook for future research directions was discussed.
