Abstract
A method and apparatus for an application aware traffic shaping service node architecture is described. One embodiment of the invention, the service node architecture includes a set of one or more line cards, a set of one or more processor cards and a full mesh communication infrastructure coupling the sets of line and processor cards. Each link coupling the sets of line and processor cards is of equal capacity. A line card includes a physical interface and a set of one or policy network processors, with the network processors performing deep packet inspection on incoming traffic and shaping outgoing traffic. Processors cards include a set of one or more policy generating processors. According to another embodiment of the invention, the service node generates a set of statistics based on the incoming traffic and continually updates, in real-time, traffic shaping policies based on the set of statistics.
