ITC/USA 2008 Conference Proceedings / The Forty-Fourth Annual International Telemetering Conference and Technical Exhibition / October 27-30, 2008 / Town and Country Resort & Convention Center, San Diego, California / ARINC 664 presents the designers of data acquisition systems challenges not previously seen on other aircraft avionic buses. Among the biggest challenges are providing the test instrumentation system with the capacity to process two redundant Ethernet segments that may be carrying packet traffic at near wire-line speed. To achieve this level of performance, the hardware and software must not only perform mundane operations, like time stamping and simple virtual link MAC filtering, but also need to implement core ARINC 664 functions like redundancy management and integrity checking. Furthermore, other TCP/IP operations, such as IP header checksum, must also be offloaded to the hardware in order to maintain real-time operation. This paper describes the implementation path followed by TTC during its development of an ARINC 664 network monitor used in a large commercial aircraft flight test program.
