MILESTONE: Openflow protocol 1.3+ - Improve handshake

Bug Resolved Done Michal Polkorab Jozef Bacigal Mon, 26 Sep 2016 12:51:05 +0000 Mon, 27 Sep 2021 09:01:54 +0000 Wed, 2 Nov 2016 13:03:17 +0000 General 0 2 <p>Actually, we accept in ofjava only OF messages in version v1.0/1.3.<br/> <a href="https://git.opendaylight.org/gerrit/#/c/26087" class="external-link" target="_blank" rel="nofollow noopener">https://git.opendaylight.org/gerrit/#/c/26087</a> will allow any version of Hello message for negotiation (up to v1.5). With this we could know the highest supported version by device however after successful handshake we should not communicate in other version than negotiated. </p> <p>If we want to use features from higher versions there are some official extensions for v1.3 including for example bundles from v1.4/1.5 (<a href="https://www.opennetworking.org/images/stories/downloads/sdn-resources/onf-specifications/openflow/openflow-extensions-1.3.x-pack2.zip" class="external-link" target="_blank" rel="nofollow noopener">https://www.opennetworking.org/images/stories/downloads/sdn-resources/onf-specifications/openflow/openflow-extensions-1.3.x-pack2.zip</a>). Another possibility is support higher protocol versions.</p> <p>...at this time I'm going to investigate also ofplugin side of handshake.</p> <p>merged in master branch</p> <p>(nothing special necessary on OFP side)</p> Development External issue ID 6805 External issue URL Issue Type ODL SR Target Milestone Rank 0|i0338n:
