1 Introduction

The TTE-Switch Lab Space is a 25x Ethernet port switch based on the TTE-Controller HiRel (TT6802-2-

SW-B) and serves as a development platform for TTEthernet.

TTEthernet is a fault-tolerant real-time communication protocol for safety-relevant systems that makes it

possible to conveniently configure the deterministic processing of critical Ethernet traffic (time-triggered,

ARINC 664 P7 [1]) and non-critical, standard Ethernet traffic (IEEE 802.3 [4]) in one physical infrastruc-

ture.

Switching Function

The TTE-Switch Lab Space is a high-performance deterministic Ethernet switch and provides 25 Ethernet

ports in total:

• 6x 100/1000 Mbit/s ports

• 19x 100 Mbit/s ports

These ports can also be used to monitor traffic. The TTE-Switch Lab Space has built-in mechanisms for

traffic policing and fault isolation.

Virtual Links and Protocol Support

The TTE-Switch Lab Space allows configuring up to 4096 virtual links (VL). Virtual links can be configured

with 8 priorities and a bandwidth allocation gap (BAG) of 0.5 ms to 1600 ms. The network configura-

tion 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 Diagnostics

The TTE-Switch Lab Space features an integrated CPU for management. Switch management relies on

SNMP. Data loading is possible through TFTP.
