Abstract: Systems, methods, and apparatus for generating data packets and testing a packet switching system are provided. For example, a data packet diagnostic system includes an input queuing subsystem comprising a set of data queues, an injecting unit, and a diagnostic unit. Each data queue is coupled with a separate functional read/write path and debug read/write path. The injecting unit injects test data packets into at least one of the data queues via its respective debug read/write path. The test packets can then be processed (e.g., routed) through a data packet processing environment. In some implementations, packets are communicated via the data packet processing environment back to the input queuing subsystem, where the diagnostic unit can read present contents of at least one of the data queues to determine whether the present contents satisfy a predetermined test profile according to the injected data packets.
