Abstract
The present invention includes a method and apparatus for filtering IP packets based on events within a computer network. More specifically, the present invention includes a services management system, or SMS. The SMS manages network connections between a series of client systems and a router. An access network control server (ANCS) manages the configuration of the router. The SMS monitors activities or events that occur within the network. In response to these events, the SMS dynamically downloads filtering profiles to the ANCS. The ANCS then uses the downloaded filtering profiles to reconfigure the router. The router then uses the filtering rules to selectively discard or forward IP packets received from the client systems.
