[Nsi-wg] new state machine

Hi all, Here is a slide of a new state machine. Here, prov.cf/rel.cf does not mean data plane failure, but means confirmation of delivery of a prov/rel request to all the children. I am not sure how we can handle prov.fl (and rel.fl) messages. Since they are not related to data plane, they are almost fatal. Going back to the previous state may not make sense. (In most cases, such .fl message will not be sent back, but time out will happen). Tomohiro
