After this course, participants will be able to perform the following:

  • Understand the architecture of DPDK
  • Integrate and configure DPDK with Linux
  • Use the DPDK libraries and APIs
  • Implement the DPDK packet flow in a multi-core environment
  • Deploy several different data path processing applications
  • DPDK 1.7
  • Developers involved in data plane packet processing on Intel architecture general purpose processors
  • System architects and system integrators involved with the design of control and data plane systems

Day 1

Introduction to DPDK

  • Benefits of using DPDK and general purpose architecture over NPU
  • Data plane and control plane consolidation
