Abstract: A packet forwarding method, apparatus, and device, and a chip system are disclosed. The method is applied to a packet forwarding device including a processor and a coprocessor, and includes: The packet forwarding device receives a first packet, and queries a flow table based on flow identification information carried in the first packet. When a target flow entry matching the flow identification information carried in the first packet exists in the flow table, the coprocessor of the packet forwarding device forwards the first packet based on the target flow entry. The flow entry is a session entry created by the processor of the packet forwarding device based on flow identification information of any received flow, and the target flow entry is a session entry created by the processor of the packet forwarding device based on flow identification information of a first flow to which the first packet belongs.
