[0004] The disadvantages of the prior art solutions are: firstly, when a new file is released in the source server, if the file in the CDN node does not arrive at the scheduled time, the file in the CDN node cannot be updated in time, which will cause CDN The file in the node is inconsistent with the file in the source server; secondly, the condition for updating the file synchronously is only to compare the last modification time of the file, without comparing the integrity of the file, the accuracy is not high, because although the modification time of some files is the same, However, the contents of the files are substantially different, which will also lead to inconsistencies between the files in the CDN node and the files in the source server

Embodiment Construction
[0047] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.
[0048] Please refer to figure 1 , figure 1 A flowchart of a CDN node file synchronization method proposed by an embodiment of the present invention. As shown in the figure, the method at least includes:
[0049] S101, when it is detected that a new file is published by the source server, and there is an original file corresponding to the new file in the CDN node associated with the source server, acquire the same type of file as the new file and the ...

The embodiment of the invention discloses a CDN (Content Delivery Network)-node file synchronization method which includes the following steps: when it is monitored that a new file is issued in a source server, and that an original file corresponding to the new file exists in a CDN node correlated with the source server, the same kind of file information of the new file and the original file is obtained; whether the same kind of file information of the new file and the original file is identical is judged; and if the same kind of file information of the new file and the original file is not identical, the new file is used to update the original file in the CDN node. The embodiment of the invention also discloses a CDN-node file synchronization device. Through adoption of the CDN-node file synchronization method and device, the accuracy of file information comparison can be improved and file synchronization in the CDN node is timelier.
Description
technical field [0001] The invention relates to the field of network technology, in particular to a CDN node file synchronization method and device. Background technique [0002] CDN (Content Delivery Network, Content Distribution Network) is a layer of intelligent virtual network based on the existing Internet by placing node servers all over the network. Comprehensive information such as , load status, distance to the user and response time will redirect the user's request to the service node closest to the user. Its purpose is to enable users to obtain the required content nearby, solve the network congestion of the Internet, and improve the response speed for users to obtain network content. [0003] In the existing technical solution, when the file on the CDN node reaches the predetermined time, the CDN node requests the source server to synchronize the corresponding file, and compares the last modification time of the file in the source server with the file modificati...
