The Data acQuisition Development Kit

DQDK is a framework to develop data acquisition systems over UDP. DQDK uses AF_XDP with an ultra-lightweight UDP/IP stack. DQDK exploits COTS hardware architectures and advanced OS features to achieve high-performance zero-loss DAQ.

Build

For Ubuntu

apt install clang llvm libelf-dev libpcap-dev gcc-multilib build-essential linux-tools-common linux-tools-generic linux-headers-$(uname -r) m4 libnuma-dev libdpdk-dev

For RHEL/CentOS

sudo yum --enablerepo=powertools install llvm clang elfutils-libelf-devel libpcap-devel m4 numactl-devel dpdk-devel

git clone --recursive https://github.com/kit-ipe/dqdk.git
cd dqdk/src
