Hi, Since the optical networks use the graceful shutdown procedure (and mandated in UNI 1.0) so the use of ResvTear Message is not seen. However the UNI 1.0 draft mentions that ResvTear is supported in UNI 1.0 to be compatible with RSVP. How is the reception of ResvTear to be handled (if it comes) ? Is it to be ignored or accepted ?
