Traffic generators, methods, and computer readable storage media for testing a network are disclosed. A scheduler may determine a sequence of packets to be transmitted, each packet in the sequence of packets belonging to one of a plurality of flow control groups. A packet generator may generate packets in the determined sequence and output completed packets for transmission over a network under test. The packet generator may include a first processing engine and a last processing engine configured as a pipeline to perform respective sequential stages of a packet generation process, and a first bank of first-in-first-out (FIFO) queues including a plurality of FIFO queues corresponding to the plurality of flow control groups. The first processing engine may store first packet forming data associated with each flow control group in the corresponding FIFO queue of the first bank of FIFO queues.

Traffic generator with priority flow control

Port units, methods, and computer readable storage media for testing a network are disclosed. A traffic generator may generate and transmit test traffic over a network under test, the test traffic including a plurality of interleaved packet streams, each traffic stream associated with one of a plurality of flow control groups. A traffic receiver may receive flow control packets from the network under test. The traffic generator may be configured to stop transmission of all packet streams associated with one or more paused flow control groups when the traffic receiver receives a flow control packet identifying the one or more paused flow control groups.
