Abstract

The invention is applicable to the technical field of Internet of Things, and particularly relates to a file caching method and device, an edge node and a computer readable storage medium. The methodcomprises the steps of connecting a server and N pieces of Internet of Things equipment through an edge node; obtaining a global model from the server; obtaining a file request historical record fromthe Internet of Things equipment; inputting the file request historical record into the global model to obtain a file recommendation list; obtaining and caching a target file from the server accordingto the file recommendation list. Thus, the edge node can pre-cache the files with relatively high relevance with the Internet of Things equipment, so that the probability that the Internet of Thingsequipment hits the file cached in the edge node when requesting the file from the edge node can be improved, and the problem of network delay of data transmission can be solved.

Description

technical field [0001] The present application belongs to the technical field of the Internet of Things, and in particular relates to a file caching method, device, edge node, and computer-readable storage medium. Background technique [0002] For IoT devices, a computing platform centered on a remote cloud server will cause high latency in data transmission, which cannot meet the needs of real-time applications. As a new computing platform, edge computing is considered to be able to solve the network delay problem of data transmission. In edge computing, file caching can store files requested by IoT devices in edge nodes, thereby reducing the number of IoT devices sending data through the network. The number of times a remote cloud server sends a request to alleviate backhaul link congestion. However, due to the limited storage space of edge nodes, there are fewer files that can be cached, resulting in a low probability that cached files in edge nodes are requested and hit...
