Intel DPDK介绍

DPDK是X86平台报文快速处理的库和驱动的集合，大多数情况下运行在linux的用户态空间，目前最新版本1.5.0可以到官方网站dpdk.org下载。

DPDK不是网络协议栈，不提供二层，3层转发功能，不具备防火墙ACL功能，但通过DPDK可以轻松的开发出上述功能，具体可参考实例 application examples are included。

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 inbranch 1.5.0.

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, ACL, etc. Within the tree, however, variousapplication 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.
