[Nsi-wg] Question about provision + release/terminate

Hi Lets say I try to provision a connection, and that I get an ack back from the first provider. Somwhere down the tree the request fails for some reason, could be data corruption, a connection that was adminstratively removed and the notifcation was lost, cosmic ray. Whatever. What do I reply with? There is no error signalling for provision, release and terminate. Best regards, Henrik Henrik Thostrup Jensen <htj at nordu.net> Software Developer, NORDUnet
