Abstract: A packet forwarding method and device, and a system are provided, and belong to the field of communication technologies. The method includes: A first node first receives a route to a destination node sent by a second node, where the route carries an identifier of the second node and a plurality of tunnel attributes. A plurality of tunnels from the first node to the second are in a one-to-one correspondence with the plurality of tunnel attributes. The first node forwards packets with different packet attributes destined for same destination node through different tunnels. In this application, packets having different packet attributes can be forwarded over different tunnels, so that traffic steering is implemented at a routing layer, and flexibility of packet forwarding is improved.

Abstract: A channel latency determining method, a positioning method, and device, the method including obtaining, by a communications device, device location information of a calibration user equipment (UE), calculating a propagation delay according to the device location information and prestored location information of an antenna, where the propagation delay is a time between transmitting a radio signal by the calibration UE and receiving the radio signal by the antenna, calculating a time of arrival according to the radio signal transmitted by the calibration UE to the antenna, where the time of arrival is a time obtained through calculation according to a time of arrival (TOA) estimation algorithm, and determining a channel latency according to the propagation delay and the time of arrival, where the channel latency is positively correlated with the time of arrival and is negatively correlated with the propagation delay.

Abstract: Storing a predefined segment model including a first segment model type, first segment actions, a first sequence of the first segment actions, and a first segment threshold condition. A custom segment model is based on first user input, the custom segment model including a second segment model type, second segment actions, a second sequence of the second segment actions, and a second segment threshold condition. A continuous delivery pipeline model is generated based on second user input, the pipeline model comprising the predefined segment model and the custom segment model. The pipeline model is executed in response to a trigger event associated with development of an application. First execution results associated with the predefined segment model, and second execution result associated with the custom segment model are generated and compared with corresponding segment threshold conditions. Deployment of the application is triggered based on the comparison.
