  • Patent number: 7302493
    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.

  • Patent number: 6952728
    Abstract: An internet service node (ISN) enabling the provision of desired service policies to each subscriber. The ISN may contain multiple processor groups, with each subscriber being assigned to a processor group. The assigned processor group may be configured with the processing rules, which provide the service policies desired, by a subscriber. A port may determine the specific processor group to which received data is to be forwarded. A content addressable memory with masks for individual locations may be implemented to quickly determines the processor group to which received data is to be assigned to. Due to the features of the present invention, an ISN may be able to serve a large number of subscribers efficiently. The ISN may be used at the edge of an access network.
