Abstract:
1. A method, which implements centralized control plane and distributed data plane for the system comprising service boards and a main board, wherein each service board comprises an adaptation layer, and the main board comprises an adaptation layer and a main control unit, the method comprising the following steps: the main control unit of the main board generating control information and delivers the control information to the adaptation layer of the main board; the adaptation layer of the main board transmitting the control information to that of the service board; and the adaptation layer of the service board delivering the control information to the data plane and hardware engine of the service board, both of which then process data according to the information; wherein the adaptation layer delivering the control information to the data plane and hardware engine comprises the following steps: the adaptation layer calls a data plane interface to deliver the control information to the data plane; the data plane calls an interface on a hardware processing engine to deliver the control information to the hardware processing engine; or, the adaptation layer calls a data plane interface to deliver the control information to the data plane, and calls an interface on a hardware processing engine to deliver the control information to the hardware processing engine.
