Video storage method, video playing method, device and equipment

The invention relates to the technical field of network correlation, in particular to a video storage method, a video playing method, devices and equipment. The method comprises the following steps: acquiring all video requests within a preset time; estimating a target request number corresponding to each video based on all video request distribution and a historical data model within a preset time; for each piece of video data, determining a corresponding target duration based on the target request number; wherein the target request quantity is positively correlated with the target duration; the target request number is the request number in the future preset duration; storing partial data in the video data to a local storage space of the campus network; wherein the partial data is data required for playing a video corresponding to the video data of the target duration; monitoring a video request in the campus network in real time; and if partial data corresponding to the video request is stored in the local
