Railway sector has evolved serial Train Communication Networks to Ethernet based solutions. The lack of real-time traffic communication and functions isolation capabilities of traditional Ethernet has limited the adoption of standardized Ethernet based solutions. TSN overcomes the identified limitations, and it has been identified as the next generation Data Link layer for railway communications by the railway manufactures and operators.
This paper summarizes Why TSN has become the preferred next-generation network protocol for the sector, what is TSN and How is introduced within the train networks. Additionally, a proposal for a TSN-capable Edge-computing device and an advanced TSN set-up are presented in the paper
