4.7 Usage of Network Access Domains (NADs)
A given NAD represents a domain to which a set of transmission network resources (e.g., PTPs, CTPs, SNCs)
can be assigned and a given Functional Access Domain (FAD) or set of FADs). The FAD or FADs determines
the functions which can be applied to the NAD. A network resource can be assigned to only one NAD, or be
unassigned (or free). In terms of the MTNM interface, the NMS may assign a NAD to a set of resources. The
assignment of the FADs is outside the scope of the interface. This section provides an explanation of how the
NAD/FAD concept can be used.

assignment of the FADs is outside the scope of the interface. This section provides an explanation of how the
NAD/FAD concept can be used.
The network administrator can
a) assign network resources to NADs (i.e. specify owners of various resources). This is done over the
NMS-EMS interface by setting the NAD parameter (a v3.0 parameter within additionalInfo) for a set of
resources, e.g., TPs and SNCs.
resources, e.g., TPs and SNCs.
b) assign users (i.e., operators at NMS and EMS user interface) functional profiles (FAD) thereby allowing
the users to perform specific functions on designated resources (as determined by the NAD previously
assigned to the resource). One or more FADs can be associated to a given NAD. Thus according to
type of user, different types of operations are permitted on the specific NAD. Again, management of the
FADs is outside the scope of the MTNM interface.

type of user, different types of operations are permitted on the specific NAD. Again, management of the
FADs is outside the scope of the MTNM interface.
A given resource with its NetworkAccessDomain parameter set to the empty string is intended to be a “free”
resource, i.e., any users can request only MTNM operation on the resource. A given FAD can be defined to
permit or refuse access to “free” resources.
resource, i.e., any users can request only MTNM operation on the resource. A given FAD can be defined to
permit or refuse access to “free” resources.
Example use of NADs and FADs:
• some resources are marked for the NetworkAccessDomain = ”owner23”
• user44 is defined by the network administrator at the EMS to be associated with FAD = “readonly” and
to be given access to the “owner23” NAD. So, on the EMS side, “user44” is granted readonly access to
the TPs and SNCs belonging to NAD = “owner23”.
the TPs and SNCs belonging to NAD = “owner23”.
As another example, it is noted that the NAD/FAD mechanism can be used to define VPNs. In fact, a given VPN
could be seen as NAD, where the VPN operator can create/activate, and deactivate/delete SNCs using only the
routing resources belonging to such NAD/VPN (e.g., the NMS could include the NAD identifier in the
additionalCreationInfo parameter of the createAndActivateSNC operation). At the EMS level, an SNC can be
