Problems solved by technology

[0006] However, in the existing data migration method, when the edge cluster expands, the edge node server directly grabs data from the upper-layer storage, which not only increases the load and bandwidth of the upper-layer storage, but also takes a long time for data migration, which is inefficient and resource intensive. waste problem

Embodiment Construction

[0031] As mentioned in the background technology, in the existing data migration method, when the edge cluster expands, the edge node server directly grabs data from the upper-layer storage, which not only increases the load and bandwidth of the upper-layer storage, but also takes a long time for data migration. Inefficiency and waste of resources.

[0032] In order to solve the above-mentioned problems existing in the prior art, the technical solution adopted in the embodiment of the present invention associates the event with the corresponding executed action in advance, so that when the corresponding trigger condition is met, the action group corresponding to the event is automatically obtained and Execution can improve the efficiency of server operation and maintenance and improve user experience.

[0033] In order to make the above objects, features and advantages of the present invention more comprehensible, specific embodiments of the present invention will be described...

Abstract

The invention provides a data migration method and device and an edge node server. The method comprises the steps that a data migration task in the unfinished state is acquired from a preset database and inserted in a data migration list; the data migration task in the unfinished state is acquired from the data migration list, and existence of a resource file corresponding to the data migration task in the unfinished state is judged; when the judgment result is yes, the modification time of the corresponding resource file is modified into modification time when the corresponding resource file is stored according to a preset second cache mapping relation; and when the judgment result is no, the edge node server in which the corresponding resource file is located is determined through a second load balancer according to the preset second cache mapping relation, and the corresponding resource file is grabbed from the determined edge node server and stored. According to the scheme, the data migration efficiency can be enhanced in edge clustering and capacity expanding and the resource can be saved.

Description

technical field [0001] The present invention relates to the field of content distribution network, in particular to a data migration method and device, [0002] Edge node server. Background technique [0003] Content Delivery Network (CDN), by placing node servers all over the network, builds a layer of intelligent virtual network on the basis of the existing Internet, and publishes the content of the website to the "edge" of the network closest to the user. So that users can get the content they need nearby, so as to alleviate the network congestion and improve the response speed of the website. Technically, it fully solves the problem of slow response speed of users visiting websites due to reasons such as small network bandwidth, large number of user visits, and uneven distribution of outlets. [0004] An edge cluster is a service cluster composed of multiple edge nodes and load balancers. Among them, the edge node is responsible for storing data and providing the cach...
