############# Paragraph (no number)
Data Plane Development Kit (DPDK) is a library hosted by The Linux Foundation
to accelerate packet processing workloads (https://www.dpdk.org/).
The ``DpdkNetDevice`` class provides the implementation of a network device which uses DPDK’s fast packet processing abilities and bypasses the kernel. This class is included in the ``src/fd-net-device model``. The ``DpdkNetDevice`` class inherits the ``FdNetDevice`` class and overrides the functions which are required by |ns3| to interact with DPDK environment.
The ``DpdkNetDevice`` for |ns3| [Patel2019]_ was developed by Harsh Patel,
Hrishikesh Hiraskar and Mohit P. Tahiliani. They were supported by Intel
Technology India Pvt. Ltd., Bangalore for this work.
