Abstract: This application discloses a communications method and related communications apparatus and system. The method includes recovering, by a first node, when detecting that a first packet is lost, the first packet according to a local recovery mechanism. The first packet is a packet obtained based on a packet sent by at least one first terminal to at least one second terminal, and the first node is a node on a network path between each first terminal and a second terminal communicating with the first terminal. The method further includes adding a first identification information related to local recovery, and sending the first packet. This application can reduce a transmission delay and improve transmission efficiency.

Abstract: An NFC tag verification method is provided. The method is applied to a first electronic device, and includes: detecting NFC tag information of a second electronic device; performing verification on the NFC tag information based on a locally stored first verification list, to obtain a first verification result; if the first verification result is that the verification succeeds, starting to run an application service associated with the NFC tag information; sending the NFC tag information to a cloud server; receiving a second verification result obtained by the cloud server by performing verification on the NFC tag information; and if the second verification result is that the verification fails, stopping running the application service. In the solution of embodiments of this application, when verification is performed on an NFC tag, the application service is first started to run after local verification succeeds, and then cloud verification is performed.

Abstract: This application provides a subflow establishment method. A local-end device obtains an identifier of an operator currently accessed by a network interface card of the local end device. The local-end device obtains a plurality of IP addresses of a peer-end device and identifiers of operators to which the plurality of IP addresses are homed; and establishes, by matching a plurality of operators corresponding to the local-end device and the plurality of operators corresponding to the peer-end device, a subflow between an IP address pair homed to a same operator. In this way, the established subflow does not cross operators as far as possible. This reduces negative impact of cross-operator communication of some subflows on transmission performance of a multipath connection, thereby better leveraging an advantage of the multipath connection in transmission performance in comparison with a single-path connection.

Abstract: A path computation method and a related device are disclosed. The method includes: a second network device receives path requirement information and a recomputation condition that are sent by a first network device; the second network device first obtains by means of computation a path meeting a requirement according to the path requirement information, and sends description information of the path meeting the requirement to the first network device; then the second network device constantly determines whether the recomputation condition is met; and when the recomputation condition is met, the second network device performs path recomputation, and sends description information of a path obtained by means of recomputation to the first network device. Therefore sensitivity for triggering path recomputation can be improved and a quantity of communication messages between network devices can be reduced.
