Open vSwitch for NFV

Welcome to OVSNFV’s documentation!

OVSNFV is an OPNFV collaborative development project.

The OVSNFV project proposes:

  • To modify the OPNFV build to include a deployment option for the software-accelerated userspace Open vSwitch build. This change will significantly improve the performance of the NFVI for network I/O.
  • Future work to encompass collaborative development within the Open vSwitch project to improve the performance of the software-accelerated userspace Open vSwitch and increasing its suitability for Telco NFV deployments.
