摘要： In a data transmission method, a transmit end may obtain a first application message generated by a target application running on the transmit end. The transmit end encapsulates the first application message to obtain a first data frame, where the first data frame includes a first frame type identifier, and the first frame type identifier indicates that an application message included in the first data frame is a complete application message. The transmit end transmits the first data frame to a receive end based on an established QUIC connection to the receive end. After receiving the first data frame, the receive end may determine, based on the first frame type identifier in the first data frame, that the application message included in the first data frame is a complete application message.

摘要： A first network device includes a processor and a memory having instructions stored thereon that, when executed by the processor, cause the first network device to: obtain a first virtual private network (VPN) route sent by a second network device. The first VPN route includes first identification information that uniquely identifies a first VPN instance in the second network device. The first network device is also caused to generate a second VPN route according to a second VPN instance accessing a third network device and the first VPN route. The second VPN route carries second identification information and routing information of the first VPN route. The second identification information uniquely identifies the second VPN instance in the third network device. The first identification information is different from the second identification information. The first network device is further caused to send the second VPN route to the third network device.

摘要： A packet transmission method, device, and system for network technologies are disclosed. A first network device receives, by using a first VPLS instance a packet to be sent to a user-side device connected to the second network device. The first network device forwards, based on an association relationship between the first VPLS instance and the first VPWS instance, the packet to a second VPWS instance in the second network device by using the first VPWS instance. A VPLS instance is associated with a VPWS instance in the first network device. A packet that is received by using the VPLS instance and that is to be sent to a user-side device can be forwarded by using the associated VPWS instance, so that pressure to learn a MAC address for packet transmission is reduced, and forwarding performance of the system is ensured.
