ONGOING

DONE

  • Pack and unpack of new and modified messages.
  • Rename ’stats’ framework into the ’multipart’ framework.
  • Move port list description to its own multipart request/reply.
  • Create flexible property structure to express table capabilities.
  • Add capabilities for table-miss flow entries.
  • Add next-table (i.e. goto) capabilities
  • Move table capabilities to its own multipart request/reply.

B.11.2 More flexible table miss support

TODO

ONGOING

DONE

  • Add capabilities to describe the table-miss flow entry (EXT-123).
  • Remove table-miss config flags (EXT-108).
  • Define table-miss flow entry as the all wildcard, lowest priority flow entry (EXT-108).
  • Mandate support of the table-miss flow entry in every table to process table-miss packets (EXT-108)
  • Change table-miss default to drop packets (EXT-119).

B.11.3 IPv6 Extension Header handling support

TODO

ONGOING

DONE

  • Hop-by-hop IPv6 extension header is present.
  • Router IPv6 extension header is present.
  • Fragmentation IPv6 extension header is present.
  • Destination options IPv6 extension headers is present.
  • Authentication IPv6 extension header is present.
  • Encrypted Security Payload IPv6 extension header is present.
  • No Next Header IPv6 extension header is present.
  • IPv6 extension headers out of preferred order.
  • Unexpected IPv6 extension header encountered

B.11.4 Per flow meters

TODO

ONGOING

DONE

  • Simple rate-limiter support (drop packets).
  • Flexible meter framework based on per-flow meters and meter bands.
  • Meter statistics, including per band statistics.
  • Enable to attach meters flexibly to flow entries.

B.11.5 Per connection event filtering

TODO

ONGOING

  • Set default filter value to match OpenFlow 1.2 behaviour.

DONE

  • Add asynchronous message filter for each controller connection.
  • Controller message to set/get the asynchronous message filter.
  • Remove OFPC_INVALID_TTL_TO_CONTROLLER config flag.

B.11.6 Auxiliary connections

TODO

  • Enable switch to create auxiliary connections to the controller.
  • Mandate that auxiliary connection can not exist when main connection is not alive.
  • Add auxiliary-id to the protocol to disambiguate the type of connection.
  • Enable auxiliary connection over UDP and DTLS.

ONGOING

DONE

B.11.7 MPLS BoS matching

TODO

ONGOING

DONE

  • A new OXM field OXM_OF_MPLS_BOS has been added to match the Bottom of Stack bit (BoS) from the MPLS header (EXT-85)

B.11.8 Provider Backbone Bridging tagging

TODO

ONGOING

DONE

  • Push and Pop operation to add PBB header as a tag.
  • New OXM field to match I-SID for the PBB header.

B.11.9 Rework tag order

TODO

ONGOING

DONE

B.11.10 Tunnel-ID metadata

  • Remove defined order of tags in packet from the specification.
  • Tags are now always added in the outermost possible position.
  • Action-list can add tags in arbitrary order.
  • Tag order is predefined for tagging in the action-set.TODO

ONGOING

DONE

  • New OXM Field to match tunnel-id.

Duration for stats

TODO

ONGOING

DONE

  • Duration for meter stats.
  • Done for port, queue and group stats

Cookies in packet-in

TODO

ONGOING

DONE

  • Cookie field was added to the packet-in message (EXT-7).
  • This field takes its value from the flow the sends the packet to the controller. If the packet was not sent by a flow, this field is set to 0xffffffffffffffff.

B.11.13 On demand flow counters

TODO

ONGOING

DONE

  • New flow-mod flags have been added to disable packet and byte counters on a per-flow basis. Disabling such counters may improve flow handling performance in the switch.
