Abstract
A method and apparatus for a distributed control plane. In one embodiment of the invention, a primary control card distributes control plane process instances among one or more secondary cards, including a secondary control card and/or one or more Advanced Service Engine (ASE) cards. The primary control card associates particular control messages with particular control plane process instances. Upon a line card receiving a control message that is associated with a particular control plane instance, the line card forwards the control message directly to that particular control plane instance.
