NDN-DPDK is a set of high-speed Named Data Networking (NDN) programs developed with the Data Plane Development Kit (DPDK). Included are a network forwarder and a traffic generator.

This software is developed at the Advanced Network Technologies Division of the National Institute of Standards and Technology. It is in pre-release stage and will continue to be updated.
