What it is
Intel® DPDK is a set of libraries and drivers for fast packet processing on x86 platforms. It runs mostly in Linux userland.
This project tracks the Intel® DPDK and includes all major public contributions. The most recent patches and enhancements, provided by the community, are available in master branch.
Main libraries
- multicore framework
- huge page memory
- ring buffers
- poll-mode drivers
Usage
These libraries can be used to:
- receive and send packets within the minimum number of CPU cycles (usually less than 80 cycles)
- develop fast packet capture algorithms (tcpdump-like)
- run third-party fast path stacks
For example, some packet processing functions have been benchmarked up to 160 Mfps (million frames per second, using 64-byte packets) with a PCIe Gen-2 NIC.
What it's not
Intel® 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 with the development of such features.
If you need some specific drivers or networking stacks, you should contact a company that provides such extensions.

The Packet Processing project currently includes the Intel® Data Plane Development Kit (Intel® DPDK), the Intel® DPDK Accelerated Open vSwitch (Intel® DPDK vSwitch) Openstack patch to enable the Intel® DPDK vSwitch to be utilized within an Openstack cloud, as well as drivers and patches in support of Intel® QuickAssist Integrated Acceleration. The Data Plane Performance Demonstrators are example apps can be used and customized in development as well.
