1 Introduction
The TTE-Switch A664 Lab v2.0 supports laboratory testing efforts of TTEthernet.
TTEthernet is a fault-tolerant real-time communication protocol for safety-related systems that makes it
possible to conveniently configure the deterministic processing of critical Ethernet traffic (time-triggered,
ARINC 664 P7 [2]) and non-critical, standard Ethernet traffic (IEEE 802.3 [6]) in one physical infrastructure.
Switching function
The TTE-Switch A664 Lab v2.0 is a high-performance deterministic Ethernet switch that makes it possible
to implement critical network-centric applications and process packets on all its 24 ports with full-line
speeds, operating in full-duplex mode:
• 6 x triple-speed 10/100/1000 Mbit/s ports, and
• 18 x 10/100 Mbit/s ports
One additional port is available for traffic mirroring. The TTE-Switch A664 Lab v2.0 has built-in mecha-
nisms for traffic policing and fault isolation.
Virtual links and protocol support
The TTE-Switch A664 Lab v2.0 allows configuring up to 4096 virtual links (VLs). Virtual links can be
configured with 8 priorities and a bandwidth allocation gap (BAG) of 0.01 ms to 1310.71 ms. The net-
work configuration is stored in the non-volatile memory of the switch (256 Mbit). It is optionally possible
to configure IEEE 802.1Q VLANs. Profiled IP/UDP, redundancy management, and traffic shaping are
implemented in hardware.
Data loading and diagnosis
The built-in management module runs on a separate CPU and allows for data loading and the querying
of the network status via SNMP. Data loading is done according to ARINC 615A-3/TFTP and ARINC 665-
loadable software parts.
