The European spacecraft industry has developed guidelines for generic satellite development known as SAVOIR (Space AVionics Open Interface Architecture). While the current satellites on-board networks implementations are compliant with this standard, their evolution opportunities are strongly limited. New missions and new clients are always more demanding on performance on-board, leading to the conclusion that the satellite embedded network must be upgraded. One opportunity appears with Time Sensitive Networking, an IEEE Ethernet technology capable of supporting both real-time and high-bandwidth traffic. The goal of this paper is to discuss, in a qualitative study, how TSN protocols can help to integrate Quality of Service in new generation satellites.
