Problems solved by technology

[0003] At present, in CDN, data is usually cached based on URL (Uniform Resource Locator, Uniform Resource Locator), that is, data under the same URL is cached once, resulting in a large amount of data storage, resulting in a relatively large amount of data to be queried when querying. Many, the hit rate of the data is low, and the back-to-source operation is performed when there is a miss, that is, the data is obtained from the source website for caching, thereby increasing the frequency of back-to-source operations and increasing the access pressure of the source website

Abstract

The embodiment of the invention provides a data access method and device based on a content delivery network (CDN). The CDN is provided with multiple nodes. The method includes the following steps: receiving an access request in a current node; extracting resource identification information from the access request; determining whether data corresponding to the resource identification information in the access request is stored; and when the data has been stored, returning the data. The data is cached and positioned through the resource identification information, the same data can be identified for caching in the case of multiple URLs, and thus the storage amount in the same case can be reduced, the number of queries of the data during querying can be reduced, the hit rate of the data canbe improved, the frequency of back-to-source operations can be reduced, and the access pressure on a source website can be reduced.

Description

technical field [0001] The invention relates to the technical field of computer processing, in particular to a CDN-based data access method and a CDN-based data access device. Background technique [0002] CDN (Content Delivery Network, content distribution network) is often used in websites to transmit data. CDN adds a new network structure to the existing network and deploys multiple nodes for caching data so that users Data can be transmitted to or obtained from nearby nodes to provide corresponding services. [0003] At present, in CDN, data is usually cached based on URL (Uniform Resource Locator, Uniform Resource Locator), that is, data under the same URL is cached once, resulting in a large amount of data storage, resulting in a relatively large amount of data to be queried when querying. If there are too many data, the hit rate of the data is low, and the back-to-source operation is performed when there is a miss, that is, the data is obtained from the source websit...
