OnePopPrimaryUser
The OnePopPrimaryUser scenario is similar to one of the resolutions in the OnePopLogin scenario. In the OnePopPrimaryUser scenario, subscriber primary username, as identified by the PA_PRIMARY_USER_NAME attribute, is resolved to a reference for a managing SAE. The realm for this configuration accommodates a situation in which a NIC proxy provides a primary username.
Figure 1 show the resolution graph for this realm.
Figure 1: Resolution Processes for primary_user Realm
The following agents interact with resolvers in this realm:
- Directory agent VrSaeId collects and publishes information about virtual routers and the mappings between virtual routers and SAEs.
- SAE plug-in agent UserNameVr collects and publishes information about the mappings of subscriber primary usernames to VR names.
The OnePopPrimaryUser scenario provides two host configurations: a centralized configuration and a distributed configuration.
Centralized Configuration
In this configuration, a single host called DemoHost supports all agents and resolvers. When a NIC proxy send a subscriber’s primary username to host Demo Host, the following sequence of events occurs:
- The host passes the primary username to resolver A1.
- (Optional) Resolver A1 resolves the primary username to its domain.
- Resolver A1 forwards the primary username to resolver B1.
- Resolver B1 obtains the name of the VR associated with the subscriber’s primary username and returns the VR to resolver A1.
- Resolver A1 forwards the VR to resolver C1.
- Resolver C1 obtains the SAE reference for the SAE managing the VR and returns the SAE reference to resolver A1.
- Resolver A1 returns the SAE reference to the host.
- The host returns the SAE reference to the NIC proxy.
Figure 2 illustrates the interactions of the NIC components for this realm.

Distributed Configuration
In this configuration, the agents and resolvers are distributed among two hosts, When a NIC proxy sends a subscriber’s primary username to the host OnePopBO, the resolvers execute the same actions as they do in the centralized configuration. Figure 3 illustrates the interactions of the NIC components for this realm.
