Quantum NEC OpenFlow Plugin
<<TableOfContents()>>
Abstract
The proposal is to implement a Quantum plugin that talks to OpenFlow Controller. Each Quantum network would be mapped to an virtual layer-2 network slice on an OpenFlow enabled network. The interface between the Quantum plugin and OpenFlow Controller is RESTful API. This API is supported by two implementations:Tream Sliceable Switch (OSS) and NEC ProgrammableFlow Controller (NEC Commercial Product).
This plugin consists of two components: "Plugin" and "Agent".
- Plugin: It processes Quantum API calls and controls OpenFlow controller to handle logical networks on OpenFlow enabled network.
- agent: It runs on each compute node. It gathers a mapping beween a VIF and a switch port from local Open vSwitch and reports it to the plugin.
Requirements
- OpenFlow Controller: Trema with Sliceable Switch (distributed under Apache License version 2.0), or an OpenFlow Controller that has the same functionalities and REST API available at https://github.com/trema/apps/wiki/Sliceable-Network-Management-API .

Communication between plugin and agent
This plugin uses "common-rpc" in openstack-common for the agents to communicate with the plugin and will conform to the convention for scalable-agent-comms. The current implemetation of the plugin supports Essex and is available at https://github.com/nec-openstack/quantum-openflow-plugin . The topic name for RPC will be set to "quantum.plugin" as proposed in the blueprint scalable-agent-comms.
Integration with Nova
There are no need for additional features in Nova. This implemetation utilizes a current libvirt VIF driver and linux-net interface driver.
How to run this plugin
Devstack for this plugin is available at https://github.com/r-mibu/devstack/tree/quantum-nec-plugin . QuickStart Installer is available at https://github.com/nec-openstack/quantum-openflow-plugin/tree/folsom/quickstart . This installs Tream Sliceable Switch (OSS OpenFlow Controller) and run devstack for this plugin.
References
Essex version of Quantum NEC OpenFlow plugin is available at https://github.com/nec-openstack/quantum-openflow-plugin . Note that the implemetation of Essex version uses a dedicated VIF driver to gather a mapping beween a VIF and a switch port from local Open vSwitch. The proposed version of this plugin uses the agent for this purpose.
