OFAgent is a neutron core-plugin (ML2 mechanism driver) aims to support pure OpenFlow1.3 switches.

• Todo
  • Reduce OVS dependencies
    • patch ports, multiple logical bridges
      • https://blueprints.launchpad.net/neutron/+spec/ofagent-merge-bridges
      • https://wiki.openstack.org/wiki/Neutron/OFAgent/FlowTable
      • implement learning based on flows and packet-in. possibly with l2pop.
    • OVSDB
      • port scanning
        • use port desc and ofp_port_status instead
      • port external id
        • probably use tapXXXX, which is available as ofp_port.name. ML2 plugin already accepts tapXXXX for linuxbridge.
    • port-based VLAN
      • install appropriate flows to push/pop tags.
    • tunnel ports
      • factor out the code into "OVS" sub-driver.
    • the way to configure physical networks
      • it would be more straightforward to specify an interface (eth0) rather than a bridge (br-eth0)
    • stop assuming the existence of local ports
      • eg. setup_physical_bridges
  • neutron interface driver
  • nova interface driver
  • security group. ideally implement with flows.
    • cf. https://wiki.openstack.org/wiki/Neutron/blueprint_ovs-firewall-driver
  • l2pop
    • https://blueprints.launchpad.net/neutron/+spec/ofagent-l2pop
