TTESwitch A664 Lab

24+1 Port Gigabit/s Deterministic Ethernet Switch for Rapid System Development

The TTESwitch A664 Lab supports multi-environment development efforts for hard real-time operations in distributed systems. The Deterministic Ethernet switch enables the design of highly dependable systems with focus on high availability, reliability, integrity, security, maintainability, and safety.

With the unique ability to support three different traffic classes (IEEE 802.3, ARINC 664 p7, SAE AS6802) on one physical infrastructure it is the optimal switching solution for a large variety of application areas. Other advanced features include 1 Gbit/s full-duplex speeds, flexible physical layer configuration and extended environmental ratings. Furthermore the switch provides the full range of all technical functionalities of TTTech's certifiable series production switches.

TTE-Switch A664 Lab

One Switch - Three Standardized Traffic Classes

The TTEthernet technology implemented in this 24 port switch is a fault-tolerant real-time communication protocol for safety-related systems. It allows for convergence of standard Ethernet, ARINC 664 p7 and time-triggered traffic in parallel on one physical infrastructure. Further unique features include a fixed latency and transmission jitter in the sub-microsecond range and unmatched bandwidth efficiency while maintaining full determinism (up to 95 % utilization of available network bandwidth).
