Abstract: A data flow migration method and device are disclosed. When migration between a source virtual machine and a target virtual machine is started, determining a silent time used for processing data flow migration; and receiving, within the silent time, a data flow packet sent by a switching node; and sending the data flow packet to the target virtual machine according to the data flow packet and a data flow migration policy. In this way, the silent time is used, a newly arrived data flow is redirected, and the newly arrived data flow is directly sent to the target virtual machine according to the data flow migration policy, which avoids migration of the newly arrived data flow. Therefore, data flows that arrive at the source virtual machine are on the decrease, and system migration performance is effectively improved.

Abstract: A machine learning model training method, a service data processing method, and an apparatus are provided, which are applied to the artificial intelligence field. In a training phase, a cloud server sends a machine learning submodel to an edge server. The edge server performs federated learning with client devices in a management domain of the edge server based on the obtained machine learning submodel, to obtain a trained machine learning submodel, and sends the trained machine learning submodel to the cloud server. The cloud server fuses obtained different trained machine learning submodels, to obtain a machine learning model. According to this application, training efficiency of the machine learning model can be improved. In an inference phase, the client device processes service data by using the trained machine learning submodel. According to this application, prediction efficiency of the machine learning model can be improved.

Abstract: A method includes a server delivering a random quantization instruction to a plurality of terminals. The plurality of terminals perform random quantization on training update data based on the random quantization instruction and upload, to the server, training update data on which random quantization has been performed. After aggregating the training update data on which random quantization has been performed, the server may eliminate an additional quantization error introduced by random quantization.
