Justin, Russell, Thomas, and I brainstormed together about SFC a bit in Tokyo. There was a brief discussion related to the topic on the openstack-dev list last week as well (see the thread "[neutron][networking-sfc] API clarification questions"). Thomas built a strawman prototype, I believe, though as I understand it the conversation on openstack-dev meant that it implemented an inadequate model. I don't know what the immediate plans are, but I expect that there'll be a place for SFC in OVN. _______________________________________________ discuss mailing list discuss@openvswitch.org http://openvswitch.org/mailman/listinfo/discuss
