US 12,113,806 B2 · Packet processing method, apparatus, and system

Abstract

This application discloses a packet processing method, apparatus, and system, and belongs to the communications field. In the packet processing method, a first device receives a first packet sent by a second device. The first packet includes identifier information and first authentication information of an Ethernet ring. The first device is an edge device of the Ethernet ring, and the second device is a device outside the Ethernet ring. The first device verifies the validity of the first packet based on the identifier information and the first authentication information. The first device processes the first packet after verifying that the first packet is valid. This method improves the security of Ethernet ring networks.
