Hi OpenFlow Plugin project, VTN project would like the OpenFlow Plugin project to provide a way to solve the bug 5602 in the OFP-Li (the new plugin). This is about problems which applications face when it needs to detect the removal of flow entries. 1. It takes so long time (several seconds) to detect the removal. 2. It is possible that applications fail to detect the removal.
You can find more detailed explanation in the Bugzilla. https://bugs.opendaylight.org/show_bug.cgi?id=5602 Please note that the OFP-He (the old plugin) doesn't have this issue. First, I would like you to decide by which way we solve the problems in Boron. I think there are several ways. One way is to support FlowRemoved notification like the OFP-He does. Actually, there are patches for that way. https://git.opendaylight.org/gerrit/#/c/38639 https://git.opendaylight.org/gerrit/#/c/39906/ https://git.opendaylight.org/gerrit/#/c/39552/ Since the patch (gerrit 38639) is merged, I thought OFP project decided to take this approach. Another way is to update the operational DS (flow-node-inventory:table) immediately after the OFP-Li receives FLOW_REMOVED from openflowjava. Then, applications can detect the removal of flow entries correctly using listeners for the DS. Which way do you take for Boron? Or other way?
