Abstract: A method for determining to establish a multi-protocol label switching traffic engineering tunnel. A first PE receives an IGP notification message including information of a Mesh Group to which a second PE belongs and role information of the second PE released by the second PE. Then, it determines, according to information of Mesh Groups to which the two belong, whether the two belong to a same Mesh Group. After determining that the two belong to the same Mesh Group, the first PE determines, according to role information of the two, whether to establish the MPLS TE tunnel to the second PE.

Abstract: The technology of this application relates to a packet transmission method and a communication apparatus. The method includes a validation device obtaining an address prefix from a sending device. The validation device sends a response packet to the sending device, where the response packet indicates usage status information of the address prefix at a receiving device. In this manner, the validation device may enable, by using the response packet, the sending device to learn of the usage status information of the address prefix at the receiving device, so that the sending device processes an exception of the address prefix, to help improve accuracy of source address validation, achieve a zero false positive, and minimize a false negative.

Abstract: This application provides a route refresh method, apparatus, and system, and relates to the field of communication technologies. In solutions provided in this application, a first network device can send a plurality of first routes to a second network device in a parallel transmission manner, and can send an end indication after determining that the second network device receives the plurality of first routes. Therefore, it can be ensured that in a parallel transmission scenario, the end indication does not reach the second network device earlier than the first routes. This can avoid a problem that a service flow is interrupted because the second network device untimely ages a route that is not refreshed in a routing table.

Abstract: 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.
