Abstract

The invention discloses a resource refreshing method, device and equipment for a content delivery network (CDN). The method comprises the following steps: receiving a resource refreshing instruction for instructing a first target node to refresh a target resource, wherein the resource refreshing instruction comprises identification information of the target resource and a to-be-refreshed node set of a to-be-refreshed target resource; obtaining refresh path information from the first target node to a source node corresponding to the target resource through the to-be-refreshed node set, wherein the refresh path information comprises at least one path which is determined based on at least one dimension path factor and is used for refreshing a target resource; and according to the identification information of the target resource and the refresh path information, acquiring a refresh resource corresponding to the target resource from the source node, and updating the target resource cached by the first target node by using the refresh resource. By adopting the method, the problem of poor reliability of CDN resource refreshing is solved.

Description

technical field [0001] The present application relates to the technical field of the Internet, and in particular to a resource refresh method, device and equipment for content distribution network (CDN). Background technique [0002] With the development of the Internet, network traffic increases rapidly, which poses challenges to the quality of network services. In order to improve Internet service quality and speed up network access, content delivery network (Content Delivery Network, CDN) is gradually applied. CDN nodes can cache static resources and dynamic resources, so as to realize edge distribution and storage of resources, so that end users can access them nearby. How to refresh the cached resources to ensure that the response resources are consistent with the source site that provides the resources is very important. [0003] In an existing CDN resource refresh solution, a fixed refresh task central node of the CDN initiates a refresh task to all cache resource n...
