A cloud-based file deduplication method

Abstract

The invention discloses a cloud-based file deduplication method, which uploads the corresponding records of the URL and file content stored by itself to the cloud through different HTTP cache acceleration devices, and the cloud integrates the records uploaded by all devices and sends them to the cloud. to each HTTP cache acceleration device. After the HTTP cache acceleration device obtains the records provided by the cloud, it reads the corresponding relationship between the URL and the file content. Therefore, the acceleration function can be provided when the user accesses the URL for the first time in the local area network.

Description

technical field [0001] The invention relates to a cloud-based file deduplication method, which belongs to the field of network technology. Background technique [0002] HTTP cache acceleration is a method to accelerate access to Internet resources in a LAN by localizing Internet resources, and to cache Internet egress with high bandwidth. The principle of this method is to listen to repeated URL requests in the local area network. If the request for the same URL reaches a certain number of times, the resource pointed to by the URL will be downloaded to the local. Redirect response, which redirects external network requests in the LAN to the internal network. [0003] However, there are the following two phenomena in the prior art: 1. In the current network environment, due to the high requirements of users on website access speed, most websites will be accelerated by means of CDN nodes. The principle of CDN node acceleration is to return the server address close to the geo...

Problems solved by technology

[0006] However, the disadvantage of this typical solution is that the HTTP cache acceleration device can know the correspondence between the URL and the file only after the LAN user has accessed the URL
