A Deterministic Ethernet Solution based on Time Sensitive Networking (TSN)
The recent introduction of the IEEE 802.1Q Time Sensitive Networking (TSN) real-time extensions to Ethernet presents new options for data networks within aerospace systems. Historically the widespread use of Ethernet in real-time systems has been hampered by Ethernet’s “lossy” communication model and a general lack of determinism. TSN is an emerging technology for switched networks that provides high accuracy time synchronization, deterministic traffic scheduling and robust redundancy and path routing. These features combine to make it an attractive option for aerospace applications.
