DPDK is a set of libraries and drivers for fast packet processing. It was designed to run on any processors, knowing Intel x86 has been the first CPU to be supported. Ports for other CPUs like IBM Power 8 or EZchip TILE-Gx are under progress. It runs mostly in Linux userland. A FreeBSD port is available for a subset of DPDK features.
DPDK is an Open Source BSD licensed project. The most recent patches and enhancements, provided by the community, are available in master branch.
These libraries can be used to:
Some packet processing functions have been benchmarked up to hundreds million frames per second, using 64-byte packets with a PCIe NIC.
DPDK is not a networking stack and does not provide functions such as Layer-3 forwarding, IPsec, firewalling, etc. Within the tree, however, various application examples are included to help developing such features.
Some support and services are provided by several companies.
