Abstract: An ingress device determines a service packet belonging to a target service flow, obtains transmission quality information based on a detection packet, and reports a flow identifier and the transmission quality information to a controller. The controller determines transmission quality of the target service flow based on the flow identifier and the transmission quality information. The detection packet is at least one service packet belonging to the target service flow, and meets any one or a combination of a plurality of the following conditions: the service packet is transmitted through a target transmission network, the service packet is transmitted on a target transmission path, the service packet is received through a target port of the ingress device, the service packet is transmitted through an egress device, and the service packet has a target priority.

Abstract: This application discloses a packet transmission method, an apparatus, a device, and a computer-readable storage medium, and belongs to the field of communication technologies. For example, the method is applied to a first device. The method includes: The first device receives a first packet, where the first packet includes quality guarantee indication information and information about a first application, and the first packet belongs to the first application for which quality guarantee needs to be provided. The first device stores a correspondence between the information about the first application and the quality guarantee indication information based on the received first packet. After receiving a second packet including the information about the first application, the first device provides quality guarantee for the second packet based on the stored correspondence.

Abstract: A method for detecting a multicast service flow includes receiving, by a first node, a multicast service flow from a multicast source; encapsulating, by the first node, an In-situ Flow Information Telemetry (IFIT) extension header into a data packet in the multicast service flow, where the IFIT extension header includes a first detection identifier, and the first detection identifier is used to identify the detected multicast service flow; copying, by the first node according to a quantity of next-hop second nodes of the first node, the data packet encapsulated with the IFIT extension header; and sending, by the first node to each next-hop second node, the data packet encapsulated with the IFIT extension header. The first node is a head node in a multicast detection domain.
