Quantum is a result of discussions at the Diablo design summit around improving [[OpenStack]] networking.  Quantum is not yet officially in Openstack incubation, but we already integrate with Openstack technologies like Nova and hope to be accepted for incubation project soon.  If you're a networking geek and like to hack on [[OpenStack]], please join!

== What is Neutron? ==
 +
Neutron is an OpenStack project to provide "networking as a service" between interface devices (e.g., vNICs) managed by other Openstack services (e.g., nova).   
 +
 
 +
Starting in the Folsom release, Neutron is a core and supported part of the OpenStack platform (for Essex, we were an "incubated" project, which means use is suggested only for those who really know what they're doing with Neutron).

Neutron Mission Statement

To implement services and associated libraries to provide on-demand, scalable, and technology-agnostic network abstraction. Source

What is Neutron?

Neutron is an OpenStack project to provide "networking as a service" between interface devices (e.g., vNICs) managed by other Openstack services (e.g., nova).

Starting in the Folsom release, Neutron is a core and supported part of the OpenStack platform (for Essex, we were an "incubated" project, which means use is suggested only for those who really know what they're doing with Neutron).

If you're a networking geek and like to hack on OpenStack, please join!

  • Tempest testing project Tempest Manuals. For the Icehouse cycle, the community is undertaking a focused effort to strengthen the suite of Tempest tests for Neutron. If you are interested on contributing to this effort, please go to Icehouse Neutron Tempest push to see what is being done and to TempestAPITests for HOWTO instructions.

Using Neutron

Follow the instructions in the Networking Guide, or use the installation documentation at http://docs.openstack.org to use Neutron with OpenStack Nova.
