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 architec-ture for satellite communications was proposed and its key technologies were described.Finally,the outlook for fu-ture research directions was discussed.
