Then SM can lookup the FlowKey based on cookie, and Flow from FlowKey.</p> <p>Operating System: All<br/> Platform: All</p> OPNFLWPLUG-227

But FRM doesn't need to remeber a pair flowCookie - flowId.</p> <p>More here:<br/> <a href="https://wiki.opendaylight.org/view/OpenDaylight_OpenFlow_Plugin:Backlog:Node_Status_Reconciliation" class="external-link" target="_blank" rel="nofollow noopener">https://wiki.opendaylight.org/view/OpenDaylight_OpenFlow_Plugin:Backlog:Node_Status_Reconciliation</a></p> Blocks CONTROLLER-661 Duplicate OPNFLWPLUG-85 Development External issue ID 1477 External issue URL ODL SR Target Milestone Priority Rank 0|i02zun:
