The IEEE 802.1 Time Sensitive Networking TSN profile for Aerospace Onboard Ethernet Communications has just been consented as IEEE802.1DP/SAE AS6675. This profile has been developed jointly by the IEEE 802.1 Working Group and SAE Avionics Networks AS-1 A2 Committee to address the unique requirements of the aerospace and defense industries. IEEE802 TSN has defined a set of standards with several features, options, configurations and protocols for time-sensitive communication over Ethernet. IEEE 802.1AS, which is one of the four pillars of TSN, relies on the generalized PTP gPTP protocol to distribute precise time synchronization across network devices. This paper discusses the main features of the IEEE 802.1 profile for Aerospace Onboard Ethernet Communications.
