Abstract: A training apparatus used for model training on a neural network in the field of artificial intelligence (AI) is disclosed. The training apparatus includes a plurality of accelerators. In a parallel processing process in which the training apparatus trains a neural network model using the plurality of accelerators, a complete weight coefficient of the neural network model is stored in the plurality of accelerators in the training apparatus in a distributed manner. Weight coefficients of the plurality of accelerators are subsequently added to obtain the complete weight coefficient. The neural network model is further trained on each accelerator based on different input data and the complete weight coefficient. Thus, the complete weight coefficient is stored in the plurality of accelerators in the training apparatus in a distributed manner, to reduce video random access memory (RAM) consumption of the training apparatus in a training process of the neural network model.

Abstract: This application discloses a flow entry generating method and apparatus. The method includes: receiving a service path establishment request, where the service path establishment request includes a constraint, a source device, and a target device; finding, in a data transmission network according to a cross-layer information model, a service path that meets the constraint and is from the source device to the target device, where the cross-layer information model is a model that describes, at a same layer, an overall topology relationship between an IP layer and an optical layer; and generating a respective corresponding flow entry for each forwarding device in the service path, and sending the flow entry to a corresponding forwarding device. This application can greatly reduce time complexity of computing the service path, and improve efficiency of computing the service path, thereby improving efficiency of generating a flow entry.

Abstract: Example wireless communication methods and apparatus are described. One example method includes a terminal initiates a reestablishment procedure when a handover procedure of the terminal fails. When a base station reselected by the terminal is a base station (that is, a target base station) to which the terminal is handed over in a handover procedure, and because a key of the base station is updated in the handover procedure, the base station includes key derivation information in a reestablishment message to be sent to the terminal. Therefore, the terminal can update a key of the terminal based on the key derivation information, so that the key of the terminal can be consistent with the key of the base station.
