Problems solved by technology

However, this refresh method will invalidate a request. For example, suppose there are 10 devices in a certain CDN node, and only one device caches the target resource. If the refresh request of the target resource is sent to all 10 devices, it is equivalent to magnifying the refresh request by 9 times, which increases the operational difficulty of the customer and the cache pressure of the CDN
[0003] Overall, the existing CDN node refresh method will lead to many invalid refresh requests, increasing the cache pressure of CDN nodes

Embodiment Construction

[0029] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, not all of them. the embodiment. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0030] For ordinary Internet users, each CDN node is equivalent to a website server placed around it. Through the takeover of DNS (Domain Name System, Domain Name System), the user's request is transparently directed to the nearest node, and the node The Chinese CDN server will respond to the user's request just like the original server of the website. Because it is closer to the use...

Abstract

The invention provides a data refreshing method and device and electronic equipment, and relates to the technical field of data processing, and the method comprises the steps: receiving a refreshing request for target data; determining whether the target data is stored in a local cache; and if the target data is stored in the local cache, refreshing the target data according to the refreshing request. According to the embodiment of the invention, the refreshing request is filtered in advance through the node server, and only the refreshing information of the data existing in the local cache istransmitted to the cache equipment for refreshing, so that the invalid refreshing request is filtered, the cache pressure of the CDN node is reduced, and the refreshing efficiency and the refreshingsuccess rate are improved.

Description

technical field [0001] The invention relates to the technical field of data processing, in particular to a data refresh method, device and electronic equipment. Background technique [0002] A Content Delivery Network (CDN) node usually contains multiple cache devices, depending on the size, generally more than 10, and the same resource (such as video, picture, etc.) is often only cached in this node On one or more cache devices, but the client does not know which devices are cached. Therefore, the traditional CDN node refresh solution is to send a resource refresh request to all cache devices in the node to ensure that the refresh is successful. However, this refresh method will invalidate a request. For example, suppose there are 10 devices in a certain CDN node, and only one device caches the target resource. If the refresh request of the target resource is sent to all If there are 10 devices, it is equivalent to amplifying the refresh request by 9 times, which increase...
