DPDK enables the telecommunications industry to implement performance-sensitive applications like the 5G wireless base stations, equipment for mobile networks, and voice in purpose built and cloud native form factors. 


Sample applications

DPDK source code, latest release, and documentation are hosted on dpdk.org. Besides providing the efficient packet processing framework, DPDK also packages a comprehensive number of sample applications to build from.

These sample applications provide an out-of-box experience for benchmarking and system assessments as well as providing the building blocks for Proof of Concept.

Arm features

Support for latest Arm architecture features are included in DPDK drivers and libraries to maximize performance.

  • Vector processing to increase data path throughput
  • Lock-free algorithms are used in libraries to provide scalability across large number of cores in a SoC.
  • C11 memory model is used wherever possible to leverage relaxed memory model for Arm architecture.
  • Memory barriers have been tuned in drivers to be optimal for Arm platforms.

All these features help provide better instructions per cycle (IPC) and improve the overall performance.

Ecosystem

Along with Arm, ecosystem partners such as Marvell, NXP and others contribute to the development and maintenance of DPDK.

Continuous Integration and Continuous Deployment (CI/CD) has been enabled for Arm. Now, every patch submitted to the DPDK mailing list is compiled and tested on Arm platforms, which ensures that DPDK code always works well on Arm platforms. Travis CI also enables a service where developers can validate their patches on Arm platforms.
