The list of remaining work items for OpenFlow 1.1 is below. It is
probably incomplete.
- * Implement Write-Actions instruction.
- [required for 1.1+]
-
* The new in_phy_port field in OFPT_PACKET_IN needs some kind of
implementation. It has a sensible interpretation for tunnels
but in general the physical port is not in the datapath for OVS
reasonable performance.
[required for OF1.1+]
- * Groups.
-
- * Type all
- [required for OF1.1+]
-
- * Type select
- [optional for OF1.1+]
-
- * Type indirect
- [required for OF1.1+]
-
- * Type fast failover
- [optional for OF1.1+]
-
- * Statistics
- [optional for OF1.1+]

OpenFlow 1.2
------------
on the change log at the end of the OF1.2 spec. I didn't compare the
specs carefully yet.)
+ * Action translation needs some work to transform OpenFlow 1.1
+ field modification actions into OpenFlow 1.2+ "set-field"
+ actions, because OpenFlow 1.2 dropped support for the OF1.1
+ actions.
+
OpenFlow 1.3
------------
end of the OF1.3 spec, reusing most of the section titles directly. I
didn't compare the specs carefully yet.)
- * Send errors for unsupported multipart requests.
- [required for OF1.3+]
-
* Add support for multipart requests.
+ Currently we always report OFPBRC_MULTIPART_BUFFER_OVERFLOW.
[optional for OF1.3+]
* Add OFPMP_TABLE_FEATURES statistics.
[optional for OF1.3+]
* More flexible table miss support.
+ This requires the following.
+ - Change the default table-miss action (in the absense of table-miss
+ entry) from packet_in to drop for OF1.3+. Decide what to do if
+ a switch is configured to support multiple OF versions.
[required for OF1.3+]
* IPv6 extension header handling support. Fully implementing this
optimization in some cases for the software switch.
[optional for OF1.3+]
+ONF OpenFlow Exensions for 1.3.X Pack1
+--------------------------------------
+
+OpenFlow 1.3 has a bunch of ONF extentions.
+Many of them are necessary for OpenFlow 1.4 as well.
+
+ * Flow entry notifications
+ This seems to be modelled after OVS's NXST_FLOW_MONITOR.
+ [EXT-187]
+ [required for OF1.4+]
+
+ * Role Status
+ [EXT-191]
+ [required for OF1.4+]
+
+ * Flow entry eviction
+ OVS has flow eviction functionality.
+ table_mod OFPTC_EVICTION, flow_mod 'importance', and
+ table_desc ofp_table_mod_prop_eviction need to be implemented.
+ [EXT-192-e]
+ [optional for OF1.4+]
+
+ * Vacancy events
+ [EXT-192-v]
+ [optional for OF1.4+]
+
+ * Bundle
+ Transactional modification. OpenFlow 1.4 requires to support
+ flow_mods and port_mods in a bundle.
+ (Not related to OVS's 'ofbundle' stuff.)
+ [EXT-230]
+ [required for OF1.4+]
+
+ * Table synchronisation
+ [EXT-232]
+ [optional for OF1.4+]
+
+ * Group notifications
+ [EXT-235]
+ [optional for OF1.4+]
+
+ * Bad flow entry priority error
+ Probably not so useful to the software switch.
+ [EXT-236]
+ [optional for OF1.4+]
+
+ * Set async config error
+ [EXT-237]
+ [optional for OF1.4+]
+
+ * PBB UCA header field
+ [EXT-256]
+ [optional for OF1.4+]
+
+ * Duplicate instruction error
+ We already have ONFBIC_DUP_INSTRUCTION.
+ [EXT-260]
+ [required for OF1.4+]
+
+ * Multipart timeout error
+ [EXT-264]
+ [required for OF1.4+]
+
+OpenFlow 1.4
+------------
+
+ * More extensible wire protocol
+ Many on-wire structures got TLVs.
+ [EXT-262]
+ [required for OF1.4+]
+
+ * More descriptive reasons for packet-in
+ Distinguish OFPR_APPLY_ACTION, OFPR_ACTION_SET, OFPR_GROUP,
+ OFPR_PACKET_OUT. NO_MATCH was renamed to OFPR_TABLE_MISS.
+ [EXT-136]
+ [required for OF1.4+]
+
+ * Optical port properties
+ [EXT-154]
+ [optional for OF1.4+]
+
+ * Flow-removed reason for meter delete
+ Report flow removal due to meter deletion with OFPRR_METER_DELETE.
+ [EXT-261]
+ [optional for OF1.4+]
+
+ * Meter notifications
+ [EXT-235]
+ [optional for OF1.4+]
