TSN is a set of IEEE 802.1 standards and technologies that bring bounded latency, low packet delay variation and guaranteed packet delivery to conventional Ethernet networks. While TSN has been deployed in residential, automotive and telecommunication Ethernet networks, its applicability to space applications is now being studied by the IEEE P802.1DP (TSN for Aerospace Onboard Ethernet Communications) Task Group.

This presentation provides an overview of how TSN can bring fault tolerance, resiliency, latency reduction and determinism to space, and how TSN Ethernet can change the economics and ecosystem for space. The author will also give a status update on the work at P802.1DP.
