Abstract

An internet service node (ISN) enabling the provision of desired service policies to each subscriber. The desired service policies for each subscriber are provided as an input. The desired service policies are translated into processing rules. Each processing rule contains a classifier and associated action. A classifier generally identifies the application data flows to which the action may be applied to provide the desired service policies. The processing rules may be generated dynamically to implement the specified service policies for each subscriber. Each data bit group may be classified to associate with a subscriber and only the processing rules corresponding to the subscriber may be applied to the data bit group to provide the desired services.
