Abstract: A communication method includes a first network device that receives a service packet from a first endpoint device, where a destination media access control (MAC) address of the service packet is a specific local MAC address of a second endpoint device, the specific local MAC address includes an indication prefix and location information, the indication prefix indicates that the specific local MAC address includes the location information, and the location information indicates an access location of an endpoint device in a network. The first network device determines an egress port from a preset routing table based on the location information in the specific local MAC address of the second endpoint device, and sends the service packet through the egress port, where the routing table includes the location information and the egress port corresponding to the location information.

Abstract: In a packet processing method, a network device obtains a first packet. The network device determines a first index value based on address information of the first packet and a neural network model. The network device determines, from an action information table based on the first index value, action information corresponding to the first packet, where the action information table includes at least one entry, and each entry corresponds to an index value and a piece of action information. The network device processes the first packet based on the action information corresponding to the first packet.

Abstract: A method implemented by a communication apparatus for processing a packet. The method includes obtaining, by the communication apparatus, a first packet, where the first packet includes a first-layer header. The first-layer header includes an identification field used to identify whether the first-layer header of the first packet includes information in a second-layer header. The communication apparatus then processes the first packet, which may include sending the first packet, forwarding the first packet, scheduling or marking the first packet, or the like.

Abstract: Embodiments provide a method, including: receiving, by a forwarding element, a packet through an inbound port; searching for, by the forwarding element, a port table according to the inbound port and determining a first offset, a first length, and an identifier of a first table; determining, by the forwarding element, a first key according to the first offset and the first length, searching for the first table according to the first key, and determining a first instruction; and processing, by the forwarding element, the packet according to the first instruction. In addition, a forwarding element is provided. In the foregoing technical solutions, before processing a packet, the forwarding element does not need to interpret a data format of the packet, so that the forwarding element can flexibly support packets in different data formats.
