Abstract
In general, techniques are described for informing services nodes of private network address information in order to apply subscriber-aware services with the services node. In some examples, a services node includes an Authentication, Authorization, and Accounting (AAA) interface to receive a AAA message, wherein the AAA message has been extended from a AAA protocol to specify a private network address of a subscriber device authenticated to an access network by the AAA server and assigned the private network address that is not routable external to the access network. A mapping module associates the public network address of subscriber data traffic with the private network address received by the AAA message. One or more service modules select one or more of a plurality of subscriber policies using the associated private network address and apply services to the subscriber data traffic in accordance with the selected subscriber policies.
