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。
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.
