Time-Sensitive Network Profile Service for Enhanced In-Vehicle Stream Reservation
Juho Lee, Sungkwon Park · 2019
Experiments and standardization work on time-sensitive networks have been actively performed as research for autonomous driving. In the in-vehicle network, layer 1 standard of IEEE 802.3 and layer 2 standard of IEEE 802.1 have been developed or are being published with the introduction of Ethernet for vehicles. However, as these standards are newly established, there are some parts where interconnection with existing standards is lacking and technical issues that need to be solved emerged. One of them is about using Stream Reservation Protocol in vehicle. In this paper, we propose a method to utilize the TSN profile to solve the problem. This enables mutual compatibility between the existing standard and the new standard, and makes it possible to efficiently perform the existing stream reservation. Furthermore, we also proposed ways to extend the TSN profile to outside the vehicle and utilize it in remote driving.
