Data distribution method and system based on cloud edge collaboration

The invention relates to the technical field of data distribution, and discloses a data distribution method and system based on cloud edge collaboration, and the method comprises the steps: obtaining data information needing to be distributed from a data source; predicting a data demand of the data information, and prefetching and caching data on edge nodes according to a prediction result; distributing the data of the cloud and the edge nodes according to the prediction result; and scheduling the data by calculating the data delay of the data information calculated at the cloud end to complete cloud-edge collaborative data distribution. By intelligently allocating the data processing task between the cloud and the edge node, the resource allocation can be dynamically optimized according to the real-time requirement and the processing complexity of the task. Intelligent classification and preprocessing are performed on the data by using a community detection algorithm, and efficient processing of large-scale
