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
      • OVSDB
        • port scanning
          • currently periodically scannig the list of ports and its status using ovs-vsctl
          • use openflow port desc stats and ofp_port_status instead
        • port external id
          • there's no pure-openflow way to associate openstack device uuids to OFP ports.
          • probably use tapXXXX, which is available as ofp_port.name. ML2 plugin already accepts tapXXXX for linuxbridge.
        • add-br, set-controller, set bridge protocols
          • factor out to "OVS" sub-driver
          • use OF-Config
          • move the one-time setup code to devstack
      • port-based VLAN
        • currently using ovs-vsctl to set up port-based VLANs
        • install appropriate flows to push/pop tags instead
      • 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)
        • this will be user-visible changes
      • stop assuming the existence of local ports
        • eg. setup_physical_bridges
        • not a big deal
    • neutron interface driver
    • nova interface driver
    • security group. ideally implement with flows.
