Mec-based content caching method, node, device and storage medium

Abstract

The disclosure provides an MEC-based content intelligent caching method, node, device, and computer-readable storage medium. The method includes: collecting user request information, and periodically sending it to the mobile edge computing MEC service node, so that the MEC service node according to The collected user request information, clustering and predicting the content requested by the user, and caching the predicted content; after receiving the new user request information, parsing the user request information; according to the content requested by the user to The MEC service node queries whether the content requested by the user exists in the cached content of the MEC service node; if it exists, it obtains the content requested by the user cached by the MEC service node and returns it to the user. The disclosed method and nodes can effectively reduce the network load of the backbone network and reduce the redundant transmission of the network, thereby reducing user access delay and improving service quality.

Description

technical field [0001] The present disclosure belongs to the field of communication technologies, and in particular relates to an MEC-based content caching method, a proxy node, an MEC service node, a computer device, and a computer-readable storage medium. Background technique [0002] In recent years, with the rapid growth of Internet applications, large-scale terminal user equipment (UE, User Equipment) sends service requests, making broadband resources tight. The service requests of user equipment often cause a certain degree of delay, and the slow response speed reduces the experience of Internet applications. In order to solve the above problems, researchers have proposed content caching technology. [0003] The existing content caching scheme mainly obtains the content caching request information sent by the content server and the identification information of the service node with the content caching function through the controller, and constructs flow forwarding po...

Problems solved by technology

[0004] However, in the face of ever-increasing network files and high concurrent user access, especially Internet video files, existing content caching solutions have certain deficiencies

First of all, fixed cache is only based on the identified content information, without considering the change of user behavior or the possibility of future user requests; Deploy multiple nodes on the backbone network of the provider to ensure that users of different Internet service providers can get the same user experience, which invisibly increases the cost of deployment
