ARINC 664 is a widely used Ethernet based deterministic network (DTN) standard providing the bounded latency and jitter for safety critical applications in the avionics systems. It is not possible to generate a test suite with a feasible size without OAs if we consider all possible combinations of DTN switch configuration parameters such as the number of virtual connections, the frame size and bandwidth allocation gaps for
each connection. However, using OAs is not sufficient to generate test cases representing real-life usage of DTN switches since many combinations of VL parameters may be inadvertently eliminated by OA generation process. In this paper, we present an approach,
called chained OAs, where multiple applications of OAs are applied to the test factors to generate tests that are representative of real-life usage of DTN switches. The test cases generated by the chained OAs approach are converted into executable test scripts to be run by the AIM commercial test system.
