Given how early the project is, we decided to track our progress not using targeted release dates but rather using milestones of when we could implement certain use cases. The current proposal for these use case milestones is in the [[ https://blueprints.launchpad.net/quantum/+spec/use-case-milestones | Use Case Milestone Blueprint ]]

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!

  • Neutron Admin and API documentation in OpenStack Manuals
  • 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. Helping to develop Tempest tests (particularly API tests) is an excellent way for new contributors to learn Neutron.

Why Neutron?

  • Give cloud tenants an API to build rich networking topologies, and configure advanced network policies in the cloud.
    • Example: create multi-tier web application topology
  • Enable innovation plugins (open and closed source) that introduce advanced network capabilities
    • Example: use L2-in-L3 tunneling to avoid VLAN limits, provide end-to-end QoS guarantees, use monitoring protocols like NetFlow.
  • Let anyone build advanced network services (open and closed source) that plug into Openstack tenant networks.
    • Examples: LB-aaS, VPN-aaS, firewall-aaS, IDS-aaS (not implemented), data-center-interconnect-aaS.

    • Booting VMs on specific Neutron networks.
  • API Extensibility Framework, including extensions for:
    • "provider network", which maps Neutron L2 networks to a specific VLAN in the physical data center

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.

Forget documentation, I just want to get the code!: Neutron Downloads

Detailed information for programming against v2.0 of the Neutron web services API is available in the Neutron API Guide

If you are looking for information on using Neutron with devstack, please see: NeutronDevstack .

Neutron lets you use a set of different backends called "plugins" that work with a growing variety of networking technologies. These plugins may be distributed as part of the main Neutron release, or separately.
