Abstract: A packet forwarding method to shorten a transmission latency of an elephant flow is provided. In the method, for a first packet flow used as an elephant flow, a network device may receive a plurality of packets of the first packet flow, and determine a characteristic parameter of the first packet flow based on the plurality of packets, where the characteristic parameter of the first packet flow is used to indicate a transmission latency of the first packet flow. After determining the characteristic parameter of the first packet flow, the network device determines a forwarding policy of the first packet flow based on the characteristic parameter of the first packet flow. The forwarding policy of the first packet flow is used to indicate latency sensitivity of the first packet flow.

Abstract: A screen locking method and apparatus. After a first terminal establishes a connection with a second terminal, the first terminal sends to-be-displayed data to the second terminal so that the second terminal displays a first interface. The first terminal displays a second interface different from the first interface and obtains a first screen locking operation triggered by a user, where the first screen locking operation locks a screen of the second terminal. The first terminal sends a screen locking instruction to the second terminal in response to the first screen locking operation so that the second terminal enters a screen-locked state.

Abstract: An antenna subarray and a base station antenna are disclosed. The antenna subarray includes a reflection plate, a plurality of radiation surfaces, and a ground plate of the plurality of radiation surfaces. The ground plate is vertically disposed on the reflection plate, and includes an integrated bottom end structure and a plurality of branch structures. The bottom end structure is connected to the reflection plate, and a top end of a branch structure is connected to a radiation surface. A feeder layer is disposed on a side of the ground plate, and a dielectric layer is spaced between the ground plate and the feeder layer. A first polarized feeder and a second polarized feeder are disposed on the feeder layer. The ground plate may have both a “ground” function of a polarized feeder and a “ground” function of a balun. The first polarized feeder and the second polarized feeder can implement both a function of a polarized feeder of the radiation surface and a function of a balun feeder.

Abstract: Embodiments of the present invention provide a multi-frequency communications antenna and a base station. The multi-frequency communications antenna includes at least one low-frequency array, at least one high-frequency array, at least one circuit board disposed corresponding to the high-frequency array, and a reflection panel, where a filtering component configured to decouple filtering is disposed on the circuit board, a first end of the filtering component is electrically connected to the high-frequency array, and a second end of the filtering component is electrically connected to a signal ground layer of the circuit board. The filtering component configured to decouple filtering that is shown in this embodiment is disposed on the circuit board, which causes a small damage to an array radiation environment.
