Hi list, Recently I am reading ovn source code, there are some STATES before OVN controller shift to UPDATE_FLOWS state, one state is named CLEAR_FLOWS, which seems clear all the flows in the ovs-vswitchd before programming new flows, IMHO this will cause short traffic disruption for the VM hosted on the node.
Since in neutron l2 agent, there is now a flow persistence mechanism by leveraging flow cookie, the effect is that when the l2 agent is restarted, flow will be keeped if network topology is not changed. My question is whether ovn will implement this feature laterly or consider this feature is useless? Thanks a lot. _______________________________________________ dev mailing list dev@openvswitch.org http://openvswitch.org/mailman/listinfo/dev
