Dependencies

Application	Version
cmake	>=3.16

DPDK	22.11

System library dependencies:

• libzstd-dev
• libpcap-dev

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" -- --tx 1 --rx 0 --tx-cores 4 --total-flows 16 --dist zipf --zipf-param 1.26
