Abstract: A packet processing method implements a QoS guarantee. The method includes: obtaining a flow identification based on packet attribute information and a flow matching rule, generating a flow policy that includes a correspondence between the flow identification and a flow behavior, determining a forwarding path of a packet including the packet attribute information, sending the flow matching rule to an ingress device of the forwarding path, and sending the flow policy to a first network device on the forwarding path. The ingress device adds the flow identification to the packet including the packet attribute information, and sends the packet. The first network device receives the packet including the flow identification, obtains the flow behavior from the flow policy based on the flow identification, and processes the packet in a packet processing mode corresponding to the flow behavior.

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 header information obtaining method. The method includes: obtaining, by a communications device, a first packet, where the first packet includes a plurality of extension packet headers; and obtaining an extension header self-describing option from the first packet, where the extension header self-describing option is used to indicate information about the plurality of extension packet headers. Therefore, the communications device obtains, based on the extension header self-describing option in the first packet, a first extension packet header included in the plurality of extension packet headers. Packet header information of the extension packet header in the first packet can be obtained by using the extension header self-describing option, and the first extension packet header that needs to be parsed can be directly located from the first packet by using the obtained packet header information.

Abstract: An ingress node obtains a packet, and feature information of an application program corresponding to the packet. The feature information of the application program includes at least one of the following information: identification information and network performance requirement information of the application program. The identification information is used to identify the application program. The ingress node determines the path between the ingress node and the egress node based on the feature information of the application program and a mapping relationship between the feature information of the application program and the path between the ingress node and the egress node. The ingress mode forwards the packet through the path between the ingress node and the egress node.

A network device stores a control policy, and the control policy includes a correspondence between application feature information and an execution action. After receiving a service packet carrying the application feature information, the network device determines the corresponding control policy based on the application feature information, and processes the service packet based on the execution action in the determined control policy. In this way, by storing the control policy in the network device, the network device may determine, based on the control policy stored by the network device and for the service packet carrying the application feature information, the execution action used to process the service packet, to implement application-level service processing.
