What is Quantum?

Quantum 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, Quantum 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 Quantum).

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

Why Quantum?

  • 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, used 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, data-center-interconnect-aaS.

Using Quantum

Following the instructions in the Quantum Administrator Guide to use Quantum with OpenStack Nova.

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

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

If you are looking for information on using Quantum with devstack, please see: QuantumDevstack .

Quantum 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 Quantum release, or separately.

The set of plugins included in the main Quantum distribution and supported by the Quantum community include:

Additional plugins are available from other sources:

If you have your own plugin, feel free to add it to this list.

Current Project Status

The 2012.2 "Folsom" release includes:

  • v2.0 of the Quantum API, including support for L2 networking and IP Address Management (IPAM)
  • Integration with Keystone for API authentication
  • API Extensibility Framework, including extensions for:
    • "provider network", which maps Quantum L2 networks to a specific VLAN in the physical data center
    • "L3 routers", which supports a basic L3 router construct to route between L2 networks, and provide a gateway to external networks with support for SNAT and floating IPs.
  • Updated API Client Library and CLI, including support for filtering.
  • Horizon GUI support for:
    • Quantum network and subnet creation/deletion
    • Booting VMs on specific Quantum networks.
  • Several plugins:
