This application provides a packet processing method, network device, and system. The method includes: A first network device obtains a first data communication network DCN packet by using a hardware processing unit, where the first DCN packet is carried in a payload area of a first data frame, and the first DCN packet includes a target device identifier; the first network device determines, based on the target device identifier, by using the hardware processing unit, whether the first DCN packet is a direct packet; and when the first DCN packet is a direct packet, the first network device sends the first DCN packet to a second network device, where the second network device corresponds to the target device identifier. According to the packet processing method provided in this application, a direct packet that does not need to be processed by a current network element can be quickly forwarded by using lower-layer hardware, thereby reducing read power consumption of a CPU, and improving processing performance of the CPU. In addition, a DCN packet is carried in a payload area of a data frame, expanding a transmission bandwidth of the DCN packet.
