摘要： A packet processing method and system, and a network device are disclosed, and belong to the field of network technologies. A first network device sends a first packet to a second network device through a first tunnel, and sends a second packet to a third network device through a second tunnel. The second network device forwards the first packet to the third network device through a third tunnel. The third network device processes the first packet and the second packet. The first network device is located at a first site. The second network device and the third network device are located at a second site. The first site and the second site are connected through a wide area network. Wide area network multipath transmission may be implemented in a multi-gateway scenario.

摘要： This application discloses a packet transmission method and apparatus. The method includes: receiving, by a first device, a first packet from a second device, where the first packet includes a primary scheduling identifier, and the primary scheduling identifier is used to identify that the second device has permission to select a path; determining, by the first device, a first path used to transmit the first packet; sending, by the first device, a second packet to the second device by using the first path, where the second packet includes a following identifier, and the following identifier is used to identify that the first device sends the packet by using a transmission path selected by a device other than the first device. When the second device communicates with the first device, the first device serving as a following party sends a packet by using a transmission path selected by the second device serving as a primary scheduling party, so that the first device and the second device send packets by using the same transmission path. This can ensure that a same path is used for bidirectional packet transmission between two communication parties while ensuring service quality, in a complex SD-WAN path selection scenario.

摘要： Embodiments of this application disclose a data transmission method, a related apparatus, and a device. The method is applied to the communication field, to improve reliability of data transmission and reduce a delay of data transmission. In the method in embodiments of this application, a transmit end device obtains a plurality of pieces of packet data in a transmission sequence and encapsulates the plurality of pieces of packet data in the transmission sequence, to obtain N pieces of encapsulated packet data, and sends the plurality of pieces of encapsulated packet data to a receive end device in the transmission sequence through a plurality of communication links. In this way, the receive end device can receive, through the communication links, the plurality of pieces of encapsulated packet data sent by the transmit end device and perform unpacking processing on the plurality of pieces of encapsulated packet data, to obtain the plurality of pieces of packet data and packet sequence numbers of the plurality of pieces of packet data, determine the transmission sequence based on the packet sequence numbers of the plurality of pieces of packet data, and send the plurality of pieces of packet data in the transmission sequence. N is greater than or equal to 2.

摘要： The present invention discloses a method, an apparatus, and a system for controlling access of a user terminal, where the method includes: receiving, by a controller, an authentication packet sent by an access switching node through an established data tunnel; obtaining, by the controller, a MAC address in a source MAC address field of the authentication packet; after access authentication implemented on a user terminal corresponding to the obtained MAC address succeeds, determining, from a maintained correspondence between a MAC address of a user terminal and an interface identifier, an interface identifier corresponding to the MAC address of the successfully-authenticated user terminal, where the interface identifier is an interface identifier of an interface on the access switching node connected to the user terminal; and sending, by the controller, the determined interface identifier to the access switching node through a control tunnel established between the controller and the access switching node, and instructing the access switching node to enable the interface corresponding to the interface identifier. In this way, network security can be improved in a case in which an implementation procedure of access authentication implemented on a user terminal is simplified.
