                                          Figure A.1 – OSS-related reference points


            The internal reference points illustrated in Figure A.1 are listed as follows:
            –       oss1: This reference point covers interactions between the OSS-NaaS and OSS-NC, e.g., for wide area
                    network (WAN) connectivity management.
            –       oss2: This reference point covers interactions between the OSS-NaaS and the OSS-NS. This includes
                    interactions  related  to  network  service  lifecycle  management,  network  service  fault  and
                    performance  management,  network  service  usage  management  and  network  service  inventory
                    management.
            –       oss3:  This  reference  point  covers  interactions  between  the  OSS-NS  and  OSS-NC,  e.g.,  for  WAN
                    connectivity management, as required by a given network service orchestrated by the OSS-NS.
