Software and hardware cooperative programmable forwarding system, method and device

The invention discloses a software and hardware cooperative programmable forwarding system, method and device, and the method comprises the steps that a programmable forwarding configuration module inthe system schedules calculation resources based on a control and configuration instruction, and enables corresponding flow processing logic to be distributed to a software forwarding function moduleand a hardware forwarding function module; the hardware forwarding function module comprises a fixed function forwarding working mode and a software definition forwarding working mode, and is used for processing a fixed function data packet in the data stream and forwarding a processing result; and the software forwarding function module is composed of a software exchange process instance, processes a data packet based on scene change in the data stream based on the software exchange process instance, and feeds back a processing result to the hardware forwarding function module for forwarding. According to the system,
