The '''Data Plane Development Kit''' ('''DPDK''') is an [[open source]] software project managed by the [[Linux Foundation]]. It provides a set of [[data plane]] libraries and [[network interface controller]] polling-mode drivers for offloading [[Transmission Control Protocol|TCP]] [[packet processing]] from the [[operating system]] [[Kernel (operating system)|kernel]] to [[Process (computing)|processes]] running in [[user space]]. This offloading achieves higher computing efficiency and higher packet throughput than is possible using the interrupt-driven processing provided in the kernel.
DPDK provides a programming framework for [[x86]], [[ARM architecture|ARM]], and [[PowerPC]] processors and enables faster development of high speed data packet networking applications.<ref>Simon Stanley,[http://www.heavyreading.com/commchip/document.asp?doc_id=228565 All Change for Packet Processing] {{Webarchive|url=https://web.archive.org/web/20160821215058/http://www.heavyreading.com/commchip/document.asp?doc_id=228565 |date=21 August 2016 }}, Heavy Reading, 2013</ref><ref>Shamus McGillicudy, [http://searchsdn.techtarget.com/news/2240182264/Intel-DPDK-switch-and-server-ref-designs-push-SDN-ecosystem-forward DPDK, switch and server ref designs push SDN ecosystem forward] {{Webarchive|url=https://web.archive.org/web/20150918212638/http://searchsdn.techtarget.com/news/2240182264/Intel-DPDK-switch-and-server-ref-designs-push-SDN-ecosystem-forward |date=18 September 2015 }}, SearchSDN, April 2013</ref> It scales from mobile processors, such as [[Intel Atom]], to server-grade processors, such as [[Intel Xeon]].

==Environment==
The DPDK was originally designed to run using a [[Bare machine|bare-metal]] mode which is currently deprecated.
EAL can be extended in order to support any processors.{{fact|date=July 2022}}

DPDK is now an open-source project under the [[Linux Foundation]], supported by many companies. DPDK is governed by a Governing Board. The technical activities are overseen by a Technical Board.<ref>[http://dpdk.org/about/techboard DPDK Technical Board]</ref> Beside [[Intel]], which is a contributor to the DPDK, several other vendors also support the DPDK within their products and some offer additional training, support and professional services.

The [[pfSense]] project published a road map on 25 February 2015, in which developer Jim Thompson announced the rewriting of the pfSense core—including [[PF (firewall)|pf]], [[network packet]] forwarding and shaping, [[link bonding]], [[IPsec]]—using DPDK: "We have a goal of being able to forward, with packet filtering at rates of at least 14.88 Mpps.
[[Open vSwitch]] (OVS) has a limited set of features running userland that can be leveraged to bypass the Linux kernel OVS processing. This use case of OVS with DPDK userland is usually named OVS-DPDK. It is mostly deployed with [[OpenStack]] Neutron but it assumes that many features and [[software-defined networking]] (SDN) capabilities of Openstack are disabled. For instance, when OVS-DPDK is used, Neutron provides a lower level of security than when OVS kernel is used (no stateful firewalling, less security group).

DTS (DPDK Test Suite) is a Python-based framework for functional tests and benchmarks. It is an open-source project, started in 2014, and is hosted on dpdk.org. It supports both software traffic generators like Scapy and dpdk-pktgen, and a hardware traffic generator like [[Ixia (company)|Ixia]].<ref>Rami Rosen, [https://lwn.net/Articles/725254 Network acceleration with DPDK], lwn.net, July 2017</ref>
