DPDK releases v19.05, introduces Windows Support!

By Blog

This post originally appeared on the Microsoft Tech Community (Networking) blog, here:

By Harini Ramakrishnan 

Data Plane Development Kit recently issued the release of DPDK v19.05.

We are thrilled to share that this release marks the introduction of Windows Support in the community-maintained upstream repository! This exciting development paves the way for more core libraries and networking hardware to be supported on Windows lighting up new use cases.

DPDK is a set of fast packet-processing libraries and drivers for user-mode applications looking to optimize network performance.


The Linux foundation hosted DPDK project is a vibrant, thriving community of developers from over 25 organizations spanning networking hardware vendors, independent software vendors, OS distros and consuming open source projects.

For over a year now, we’ve had the ability to run DPDK on Windows through libraries available in the DPDK Windows draft repository. However, this meant that the Windows port needed a separate development, build and testing pipeline, consequentially trailing behind the DPDK community project by multiple releases.

With the initiation of the merge, DPDK libraries for Windows will benefit from the participation, contribution and leadership of the DPDK community. For instance, as part of this integration, DPDK libraries for Windows moved away from dependency on proprietary tool chain to using Clang-LLVM C compiler and Meson Build system.

What Next?

Wait, does this mean we can retire the DPDK Windows draft repository? Not quite, yet!

The draft repository will continue to be the development vehicle for all contributions, until we attain parity in features at the main repository. The integration of Windows Platform support has been initiated with the release of DPDK v19.05 and is expected to continue through 2019.

Watch the Roadmap page for announcements on Core libraries, Poll Mode drivers and features that will be added in the subsequent releases. As sharedbefore, we are partnering with multiple networking vendors to expand the hardware ecosystem for DPDK on Windows.

Eventually, when the integration is complete, DPDK on Windows can remain stable, up to date enjoying the quality baseline as other platforms.

Ways to Contribute

Interested in participating? Help us make DPDK on Windows more stable!

Test the DPDK libraries on Windows and share your feedback! Head over to the getting started guide.

But wait this is just a Hello world! Looking for more? Try the Windows port at the DPDK-draft-Windows repository with the v18.08 branch and readme.

Do you have questions, feedback to share or want to report bugs? Do you have new use cases to support or want to make feature requests?

Join us in the DPDK Windows Community call, under the guidance of the DPDK Technical Board to help shape the future of DPDK on Windows!

Thanks to the contributions from our partners at Intel and the DPDK Technical board for the guidance and the leadership.

Looking forward to hearing from you, Thanks for reading!

DPDK Community Lab Publishes Relative Performance Testing Results

By Blog

By Jeremy Plsek, Lincoln LaVoie and Patrick MacArthur

The DPDK Community Lab is an open, independent testing resource for the DPDK project. Its purpose is to perform automated testing on incoming patch submissions, to ensure the performance and quality of DPDK is maintained. Participation in the lab is open to all DPDK project participants.

For some time now, the DPDK Community Lab has been gathering performance deltas using the single-core packet I/O layer 2 throughput test from DTS for each patch series submitted to DPDK compared to the master branch. We are pleased to announce that the  Lab has recently been allowed to make these results public. These results are also now published to Patchwork as they are automatically generated. These results currently contain Mellanox and Intel devices, and the lab is able to support hardware from any DPDK participants wishing to support these testing efforts.

To view these results, you can go to DPDK Community Lab Dashboard via the following link: The dashboard lists an overview of all active patch series and their results. Detailed results can be viewed by clicking on the patch series. If a patch fails to merge into master, a build log will show to help identify any issues. If a patch cleanly merges into master, performance delta results will show for each participating member.

The Lab is hosted by the University of New Hampshire InterOperability Laboratory, as a neutral, third party location. This provides a secure environment for hosting equipment and generating unbiased results for all participating vendors. Lab participants, i.e. companies hosting equipment in the testing, can securely access their equipment through a VPN, allowing for maintenance and performance tuning, as the DPDK project progresses.

The Lab works by polling the Patchwork API. When new patches are submitted, the CI server merges them with the master branch and generates a tarball. Each participating system unpacks and installs the DPDK tarball and then runs the performance testing against this DPDK build. When all systems have finished testing, the CI gathers the results into our internal database to be shown on the Dashboard, and sends final reports to Patchwork to show up on the submitted patch. This allows patch submitters to utilize Patchwork to view their individual results, while also allowing anyone to quickly see an overview of results on the Dashboard. The system provides maintainers with positive confirmation of the stability and performance of the overall project.

In the future, we plan to open the Lab to more testing scenarios, such as performance testing of other features, beyond single-core packet I/O layer 2 throughput, and possibly running Unit Tests for DPDK. Additional features will be added to the Dashboard, such as showing graphs of the performance changes of master over time.
