The TTESwitch A664 Pro (19 inch) enables applications to fully utilize the potential of Deterministic Ethernet. Its aerospace certifiable hardware design enables the usage at safety-critical applications like aviation ground control stations or critical infrastructure. TTEthernet is a fault-tolerant real-time communication protocol for safety-related systems that integrates data flows of standard Ethernet (IEEE 802.3), ARINC 664 part 7 and Time-Triggered Ethernet (SAE AS6802) traffic in one physical infrastructure.

The combination of standard IEEE 802.1Q bridging, VLAN-based traffic segregation, ARINC 664 ingress policing, and strict priority scheduling makes it a capable integration point between a non-critical TSN network and a mixed-criticality TTEthernet network.
