New FRM client of Batch RPC

Bug Resolved Done Andrej Leitner Jozef Slezák Tue, 22 Mar 2016 08:42:37 +0000 Mon, 27 Sep 2021 09:01:46 +0000 Tue, 24 May 2016 08:15:20 +0000 General 0 2 <p>Hi Michal,</p> <p>Can you please provide some details on why we need <b>new</b> FRM and why can't we use the existing FRM?</p> <p>Hi Anil,<br/> it is currently WIP and under heavy testing.</p> <p>It is not meant to be a replacement of current FRM because of more restrictive behavior. In principle this alternative implementation of FRM keeps DS/config and device in sync. No other flows/groups/meters allowed. So if device gets changed via RPC and corresponding item (e.g.: flow) is not present in DS/config then as soon as the item emerges in DS/operational then it will be removed from device.</p> <p>On the other hand there is support for batched changes which enables for:</p> <ul class="alternate" type="square"> <li>consistent pushing of dependent groups, flows, meters</li> <li>faster operations as the barrier usage can be optimized and still provide valid rpc outcome for all changes.</li> <li>but in order to stay consistent all the changes have to be written atomically (at least within one node). And so this impl listens to whole node and decides the order of changes when pushing to device.</li> </ul> <p>Here is the chain in gerrit: <a href="https://git.opendaylight.org/gerrit/#/q/topic:bug5575-frm" class="external-link" target="_blank" rel="nofollow noopener">https://git.opendaylight.org/gerrit/#/q/topic:bug5575-frm</a></p> <p>merged</p> Blocks OPNFLWPLUG-651 OPNFLWPLUG-648 Development External issue ID 5575 External issue URL ODL SR Target Milestone Rank 0|i032gf:
