Abstract: This application provides a packet processing method, a device, and a system. The method includes a second network device receives an IPv6 packet sent by a first network device, where the IPv6 packet includes an IPv6 header and a first IPv6 extension header, and the first IPv6 extension header indicates that a network device receiving the IPv6 packet is to perform an action in the first IPv6 extension header on a data plane. The second network device performs the action in the first IPv6 extension header on the data plane of the second network device based on the IPv6 header and the first IPv6 extension header. This ensures that the network device receiving the IPv6 packet can normally forward the IPv6 packet.

Abstract: This application provides a packet processing method, a device, a system, and a storage medium. A first network device receives an original packet, generates an IPv6 packet based on the original packet and endpoint group (EPG) information, where the IPv6 packet comprises an IPv6 extension header and the original packet, and the IPv6 extension header comprises the EPG information, and sends the IPv6 packet. A second network device receives the IPv6 packet; obtains the EPG information from the IPv6 extension header, and processes the IPv6 packet according to a group based policy corresponding to the EPG information.

Abstract: This application discloses a communication method, and relates to the communications field. In the method, a fixed mobile interworking function (FMIF) receives an access request message that carries first authentication information of a fixed network device and that is sent by a broadband network gateway (BNG), where the first authentication information is generated by the BNG based on a dial-up packet sent by the fixed network device, and the first authentication information includes an identifier of the fixed network device. The FMIF encapsulates the first authentication message in a message format supported by a control plane interface between the FMIF and a core network device, to obtain a second authentication message; and the FMIF sends the second authentication message to the core network device through the control plane interface. The core network device performs authentication on the fixed network device based on the second authentication message.

Abstract: A packet processing method and apparatus, and a communication system are provided, and belong to the field of communication technologies. The method includes: After receiving an IPv6 packet including a first DOH, an intermediate node parses the first DOH based on a first policy, to obtain first information carried in the first DOH, and processes the IPv6 packet based on the first information. The IPv6 packet includes an RH and the first DOH is located after the RH, or the IPv6 packet does not include an RH. In this application, an intermediate node that performs parsing to obtain information carried in an IPv6 extension header may be flexibly specified, to resolve a problem that a parsing rule of an extension header of an existing IPv6 packet is not flexible enough. This application is used for packet processing.
