DPDK burst replay tool

Introduction

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

To do so, the pcap files will be cached on hugepages before being sent through DPDK.

How to play with it

Install dependencies

• dpdk-dev (obsly)
• libnuma-dev
• That's all.

NB: libpcap is not required, as dpdk-replay process pcap files manually.

Compiling and installing it

mkdir build
cd build
cmake ..
make
sudo make install

Launching it

dpdk-replay [--nbruns NB] [--numacore 0|1] FILE NIC_ADDR[,NIC_ADDR...]

Example:

dpdk-replay --nbruns 1000 --numacore 0 foobar.pcap 04:00.0,04:00.1,04:00.2,04:00.3

TODO

• Add a configuration file or cmdline options for all code defines.
• Add an option to configure maximum bitrate.
• Add an option to send the pcap with the good pcap timers.
• Add an option to send the pcap with a multiplicative speed (like, ten times the normal speed).
• Add an option to select multiple pcap files at once.
• Be able to send dumps simultaneously on both numacores.
• Split big pkts into multiple mbufs.
• Add a Python module to facilitate scripting (something like what does scapy for tcpreplay sendpfast func).
• Manage systems with more than 2 numa cores.
• Use the maximum NICs capabilities (Tx queues/descriptors).
