Abstract
A test environment includes a test packet generator, a system under test, and a test device. The test packet generator generates test packets each containing a check value (e.g., a cyclic redundancy check value). The system under test performs a known transform of at least a portion of each test packet, and generates a new check value based on the transformed packet. The test device receives the transformed packets from the system under test. The test device performs an error check based on the check value and also compares the check value with an expected check value to validate the content of each received packet.
