DPDK traffic generator

Dependencies

Application	Version
cmake	>=3.16
meson	1.3.1
DPDK	22.11

Installation instructions

1. Run setup.sh to install dependencies locally.
   • Note: you only need to run this once to install the dependencies.
2. Build with meson by running build.sh.
3. Source the paths file: source paths.sh.
4. Run Debug/bin/pktgen or Release/bin/pktgen.

Running

Like every DPDK application, one must go through the EAL arguments first, and only then consider the application specific arguments, like such:

$ sudo ./Debug/bin/pktgen $EAL_ARGS -- $PKTGEN_ARGS

To bring up the help menu from pktgen specifically, one can use a testing EAL configuration:

$ sudo ./Debug/bin/pktgen \
    --no-huge \
    --no-shconf \
    --vdev "net_tap0,iface=test_rx" \
    --vdev "net_tap1,iface=test_tx" \
    -- \
    --help

Testing

Example pktgen configuration (for testing purposes):

$ sudo ./Debug/bin/pktgen \
    -m 8192 \
    --no-huge \
    --no-shconf \
    --vdev "net_tap0,iface=test_rx" \
    --vdev "net_tap1,iface=test_tx" \
    -- \
    --total-flows 4 \
    --tx 1 \
    --rx 0 \
    --tx-cores 1 \
    --crc-unique-flows \
    --crc-bits 16 \
    --seed 0
