Anuket Project

The NFVbench project develops a toolkit that allows developers, integrators, testers and customers to measure and assess the L2/L3 forwarding performance of an NFV-infrastructure solution stack (i.e. OPNFV scenario) using a black-box approach. 

NFVbench is available as a self-contained docker container that includes the the main application and the Trex software traffic generator.

NFVbench is agnostic of the NFV platform, the controller used (ML2/OVS, ODL...), the network stack used (OVS, OVS-DPDK, VPP, SR-IOV...) and supports VLAN and VxLAN.

NFVbench is currently widely deployed in production NFV clouds around the world by multiple service providers and is mostly used for

  • on-site integrated performance benchmarking tool, which allows instant performance measurement on every deployed NFV platform
  • precise performance planning tool with high VNF density (multi-chaining)

NFVbench is also currently used as the traffic generator solution for the CNCF CNF testbed based on CNF testbed slides.

Where can I find NFVbench Docker images?

Available versions of NFVbench Docker images can be found on Docker hub:

Where is the change log for NFVbench Docker image?

No ChangeLog, look at NFVbench commit log on

 Note: there is also a GitHub mirror for NFVbench, but it is more complicated to see the association between commit history and tags

Which version of TRex is associated to a given version of NFVbench?

For a given version of NFVbench container image on Docker hub, TRex version can be found in the TREX_VER environment variable in the image history.  For
instance, NFVbench Docker image version 3.4.1 is based on TRex 2.56 as can be seen here.

For a given version of NFVbench code base, the version of TRex that would be embedded in a Docker container built from that code base is given in the
TREX_VER environment variable found in docker/Dockerfile  For instance, NFVbench code base tagged 3.6.1 is meant to be used with TRex 2.61 as can be seen in the Dockerfile.
