Abstract: A packet processing method, a forwarding device, and a packet processing system are applied to a switch, a router, or another device or system in which a control plane and a forwarding plane are separated. In the packet processing method, the forwarding device obtains a first forwarding table that corresponds to a first packet and that is configured by a control device, where the first forwarding table includes at least one data structure, and the at least one data structure includes a field value type and content corresponding to the field value type. Then, the forwarding device processes the first packet based on a field value type in the at least one data structure and content corresponding to the field value type, to obtain a field value of a field value type. Therefore, packet processing efficiency is improved.

Abstract: This application provides example packet processing methods, network devices, and systems. One example method includes obtaining, by a first network device, a first data communication network (DCN) packet by using a hardware processor, 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 processor, whether the first DCN packet is a direct packet. In response to determining that 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.
