IntroductionΒΆ
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 Controller (NEC Commercial Product)
- Trema Sliceable Switch (OSS)
This plugin consists of two components:
- Plugin: It processes Neutron API calls and controls OpenFlow controller to handle logical networks on OpenFlow enabled network.
- Layer2-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.
