Abstract

The invention provides a back-to-source method and a back-to-source device for an access request. The back-to-source method and the back-to-source device relate to the field of Internet, and solve theproblems of large back-to-source quantity and low resource utilization ratio of a father node scheme in the prior art. The back-to-source method comprises the steps of: receiving an access request ofa user by an edge node, performing consistent hashing operation on an URL (Uniform Resource Locator) carried in the access request and then determining that the URL accesses a corresponding father node server group; and requesting a source file corresponding to the URL from the father node server group. The back-to-source method provided by the invention is suitable for a CDN (Content Delivery Network), and achieves file back-to-source with flexibility, balance, and a high storage disaster tolerance capacity.

Description

technical field [0001] The invention relates to the field of the Internet, in particular to a method and device for returning an access request to the source. Background technique [0002] Acceleration nodes are node servers deployed by cloud distribution service providers all over the country. Cloud distribution service providers [0003] In order to solve the last mile problem of customer access, edge nodes are deployed all over the country to provide customers with access acceleration services nearby. However, when nodes across the country access files on the same source, edge nodes will pull back to the source if they do not have the file at first, resulting in a large amount of back-to-source; in order to solve the above problems, the upper-layer transit server under the cloud distribution architecture emerges referred to as the parent node). When the file accessed by the user is in the parent node, other edge nodes can obtain the file from the parent node without bac...
