Abstract: A device for controlling network routing configurations is configured to obtain a predicted traffic matrix and a plurality of traffic matrices, and to determine, from a plurality of clusters, arranged in a hierarchical structure over the predicted traffic matrix and the plurality of traffic matrices, a first cluster allocated to a lower hierarchy level that contains the predicted traffic matrix. Each of the clusters is associated with a routing configuration, and the plurality of clusters are allocated to at least two different hierarchy levels. The device selects, from the plurality of clusters, a second cluster allocated to a higher hierarchy level that includes at least the first cluster and a third cluster allocated to the lower hierarchy level that contains a current traffic matrix, determine a second routing configuration associated with the second cluster; and activate the second routing configuration as a network routing configuration.

Abstract: An antenna apparatus includes a ground plate, a radiator, and a signal source. The radiator is disposed on the ground plate. The signal source is configured to feed an electromagnetic wave signal of a first frequency band into the radiator. A first slot and a second slot are disposed on the ground plate. Both slots are closed slots and surround the radiator, and are used to restrain current distribution on the ground plate.

Abstract: Embodiments of this application disclose a communication apparatus. The communication apparatus may include a first transceiver, a second transceiver, and a power amplifier. The first transceiver and the second transceiver may be separately connected to the power amplifier. In this way, when it is determined that a network load is relatively low, any transceiver in the communication apparatus may be turned off. Because the turned-off transceiver no longer continues to generate power consumption, power consumption of the entire communication apparatus is reduced, to achieve an energy saving effect. In addition, when an electronic component in the communication apparatus is turned off, the power amplifier may not be turned off, and the power amplifier may still receive a corresponding radio frequency signal from a transceiver that is not turned off, to perform power amplification and send a corresponding radio frequency signal.

Abstract: A heat sink includes a base and a plurality of fins. A root of the fin is connected to the base. A heated area, a dropping pipe, and a spacing strip between the heated area and the dropping pipe are formed in the fin. A first passage and a second passage are formed between the heated area and the dropping pipe. A hydraulic diameter of a pipeline in the heated area is less than a critical dimension. A hydraulic diameter of a pipeline of the dropping pipe is greater than or equal to the critical dimension, and a pressure of liquid at an intersection of the second passage and the dropping pipe is greater than a pressure of liquid at an intersection of the second passage and the heated area.
