As a second example, consider the end-to-end connection shown in Figure E

. The end-to-end connection and component SNCs are the same as in the previous example, only 

the naming scheme is different. In this approach, the service provider wants the EMS to ensure that unique 
userLabels are used for each SNC within an EMS’s management domain. If the NMS attempts to setup an SNC 
using a userLabel that has already been assigned, the EMS will reject the request. This prevents the mistaken 
re-use of the SNC names selected by the service provider (this could happen during manual entry of SNC 
names via the NMS GUI, for example). Related SNCs can still be associated. However, in this case, the 
NativeEMSName is used to associate related SNCs.

In another approach, each EMS domain consists of a single subnetwork. The userLabel and nativeEMSName 
of an SNC are same. Further, the component SNCs of an end-to-end connection have the same userLabel and 
nativeEMSName, as shown in Figure E

. This example has the 

same advantages as Example 1 and also allows the NMS to request userLabel uniqueness from the EMS as in 
Example 2. The main disadvantage is that the EMS domain cannot be subdivided into multiple subnetworks.
