1. A broadband Internet node comprising:

  • a classify engine interfaced with the Internet, the classify engine operable to accept packets from the Internet and determine classification information for each packet, wherein the classify engine is operable to detect a SYN packet associated with a new TCP connection;

    a modify/process engine interfaced with the classify engine, the modify/process engine having plural ports, each port having an associated function; and

    a controller interfaced with the classify engine and the modify/process engine, the controller programming the classify engine to route each packet to a predetermined port of the modify/process engine based on the classification information of the packet;

    wherein the controller programs the classify engine with a dataflow program that determines classification information for the packets and detects the host/port quadruple of the new TCP connection and creates a new queue for the new TCP connection.
