Introduction

The tool is designed to provide high DPDK performances to burst any pcap dump on a single or multiple NIC port(s), while keeping it simple to use.

It’s a Linux command line tool, wrote in C and compiling on both x86_64 and arm64. It mainly use DPDK, but rely also on libnuma, which are the only tool dependencies.

The tool usage tend to looks like tcpreplay in term of simplicity. Only two args are required: one pcap file and one DPDK port address to replay on:

$> dpdk-replay foo.pcap 04:00.0

What can it do?

  • Load a pcap file: standard input format for all common dumping/analyzing/replaying tools like tcpdump, tcpreplay, wireshark etc...
  • Put all loaded packets in cache(s) to avoid reading the pcap file while its been replays.
  • Burst packets simultaneously on multiple ports (ATM, only NICs on the same NUMA can be addressed).
  • Run the same pcap several times in a row. It can be useful to extend a stress test without having to provide a bigger pcap file.
  • At the end, some stats are displayed for each ports (time spent, pkts-per-sec, total bitrate etc...)
  • Abstract DPDK stack: All EAL/mempool/ports initializations are automatically handled.

DPDK compatible versions

dpdk-burst-replay releases are compatible with DPDK LTS versions.

dpdk-burst-replay releases Tested with DPDK versions
v1.1.0 16.11.9/17.11.5/18.11.1

NB: Other intermediate versions should also works. Last versions can need some adaptation.
