Locating the SAE That Manages a Subscriber for the SRC VTA
You can use NIC proxies if the SRC VTA software needs to locate the SAE that manages a particular subscriber. For example, if the SRC VTA receives an account update event and determines that it needs to reconfigure the corresponding SAE session, the SRC VTA must find the SAE that is managing the session. The SRC VTA can do this through the NIC.
You can also use the NIC with the SRC VTA to allow the following:
Immediately activate subscriptions to quota services—The SRC VTA immediately activates a subscriber’s quota service when a deposit is made to the subscriber’s account. In this case, the NIC maps the subscriber’s identifier to the SAE reference. This scenario is for subscribers who connect to the network through routers running JunosE or Junos OS.
If you do not set up a NIC for this purpose or you use an identifier that the NIC cannot map to an SAE reference, subscribers must log out and log in again before the SRC VTA can activate their quota services when deposits are made to their accounts.
