(Adding openflowplugin-dev ML). Hi Anil,
That patch has made the new OPF (Li design) enable the flow removed notification. https://git.opendaylight.org/gerrit/#/c/38639/ But, only with that patch, the OFP does not publish the flow removed notification when the statics manager is running. To make the new OFP (Li design) publish the FlowRemoved notification even when the statistics manager is running, we need the following patch. https://git.opendaylight.org/gerrit/#/c/39906/ (And, I think the new OPF does not update the Inventory DS on the FLOW_REMOVED.) And please note that the flow-removed notification is marked as "deprecated" on the master branch now. The following patch is handling that, but I'm not sure about the decision of the OpenFlow Plugin project around that. https://git.opendaylight.org/gerrit/#/c/39552/ Regards, Hideyuki Tai From: Anil Vishnoi [mailto:[email protected]] Sent: Wednesday, June 15, 2016 12:15 To: Tai, Hideyuki <[email protected]> Cc: Dayavanti Gopal Kamath <[email protected]>; [email protected]; ovsdb-dev ([email protected]) <[email protected]>; P Govinda Rajulu <[email protected]> Subject: Re: [netvirt-dev] issue seen with OF plugin I believe there was plan to enable the flow removed notifications in Li design.

Here’s his mail for reference- ------------------------ Hi Daya, Last week I tested elan support using lithium openflowplugin. Elan module listens to openflowplugin packet-in and flow removed event(dynamic learned MAC address) messages. In the new plugin, packet-in message is supported but flow removed event message processing got changed. Now applications (like ELAN) should register for the Inventory DS listener. Once the switch sends stats message with flow removed and when the flow gets removed in inventory operational DS, the applications (which have registered to inventory Operational datastore) will receive flow-removed messages. If we disable stats we won’t receive flow removed messages from switch and Elan dynamic learned mac Address will remain present in the DS. Thanks, Govinda P --------------- We are already battling performance issues, and having to enable stats to get flow removal events is going to kill performance further We need to be able to process flow removals, *WITHOUT* having to rely on stats updates. Anil, can you please share your thoughts?
