Data Processing Method, Smart Network Interface Card, and Electronic Device

A data processing method, wherein the data processing method is applied to the smart network interface card, and the method comprises:

• a hardware layer receiving a packet to be processed, parsing the packet to be processed to obtain packet information, and looking up whether or not packet matching domain information matching the packet information is contained in the first forwarding flow table;
• in response to looking up the packet matching domain information matching the packet information from the first forwarding flow table, sending flow identification information corresponding to the packet matching domain information and the packet information to a software layer;
• a fastpath module in the software layer looking up target flow identification information matching the flow identification information from a second forwarding flow table based on the flow identification information, determining target execution action information corresponding to the packet information based on the target flow identification information;
• and
• the fastpath module processing the packet information based on the target execution action information.

A smart network interface card, comprising:

• a hardware layer and a software layer;
• the hardware layer comprises a packet parsing module, a first storage module, a first flow table lookup module, a first transmission module, and a first processing module;
• wherein
