# 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 > autoreconf -i && ./configure [--enable-debug] && make && sudo make install OR: > RTE_SDK=<RTE_SDK_PATH> make -f DPDK_Makefile && sudo cp build/dpdk-replay /usr/bin ### 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). ## BSD LICENCE Copyright 2018 Jonathan Ribas, FraudBuster.
