| − | === Communication between plugin and agent ===
| + | ---- |
| | | | |
| − | This plugin uses "common-rpc" in openstack-common for the agents to
| + | Note for Juno DevStack users: |
| − | communicate with the plugin and will conform to the convention for scalable-agent-comms.
| + | * Devstack support of NEC OpenFlow plugin is a part of the official devstack (http://github.com/openstack-dev/devstack) from Grizzly. |
| − | The topic name for RPC will be set to "quantum.plugin" as proposed in the blueprint scalable-agent-comms.
| + | * Detail instruction and sample devstack configuration examples (localrc) are available at https://github.com/nec-openstack/devstack-neutron-nec-openflow/wiki . |
| | | | |
| − | === Integration with Nova ===
| + | [[Category: Neutron]] |
| − | | |
| − | There are no need for additional features in Nova.
| |
| − | This implementation utilizes a current libvirt VIF driver and linux-net interface driver.

| |
| − | Essex version of Quantum NEC [[OpenFlow]] plugin is available at

| |
| − | The proposed version of this plugin uses the agent for this purpose.

NEC OpenFlow plugin talks to OpenFlow Controller and each Neutron would be mapped to an virtual layer-2
network slice on an OpenFlow enabled network. The interface between the Neutron plugin and OpenFlow
Controller is RESTful API. This API is supported by two implementations:
NEC ProgrammableFlow Networking Controller and
Trema Sliceable Switch.
More detail is available in networking-nec repository.
