a data communications network with at least one pop maintains a local cache database associated with each aaa service at the pop on the data communications network . each local database contains a group identification such as a domain identification corresponding to a group of users or an fqdn specifying a group of one individual , a maximum number of b - channels to provide the group of users at the pop and a dynamic b - channel session count corresponding to active b - channel connections currently provided to the group of users at the pop . actions are taken when the group attempts to exceed the maximum number of b - channels by more than a predetermined number . the actions may include assessing extra charges , denying access , and sending warning messages to appropriate recipients . the local database may be synchronized by publishing b - channel connection and disconnection events to all subscribing local databases . for proxy authentication users , the authentication information is published to the local caches of each aaa service at the pop upon the first log - in of the user so as to avoid the need to proxy each successive connection authentication to a remote aaa service .
