Using the NIC Resolver in PCMM Environments
If you are using the NIC to map the subscriber IP address to the SAE, you need to configure a NIC host. The NIC system uses IP address pools to map IP addresses to SAEs. You configure the local address pools in the application manager configuration for a policy server group. These pools are published in the NIC. The NIC maps subscriber IP addresses in requests received through the portal or Advanced Services Gateway to the policy server group that currently manages that CMTS device.
The OnePopPcmm sample configuration data supports this scenario for a PCMM environment in which you use the assigned IP subscriber method to log in subscribers and in which you use the NIC to determine the subscriber’s SAE. The OnePopPcmm configuration supports one point of presence (POP). NIC replication can be used to provide high availability. The realm for this configuration accommodates the situation in which IP pools are configured locally on each application manager group object.
The resolution process takes a subscriber’s IP address as the key and returns a reference to the SAE managing this subscriber as the value.
The following agents collect information for resolvers in this realm:
Directory agent PoolVr collects and publishes information about the mappings of IP pools to the policy server group.
Directory agent VrSaeId collects and publishes information about the mappings of policy server groups to SAEs.
