Problems solved by technology

[0004] However, in the above-mentioned back-to-origin process, the determined back-to-origin rate of the edge node may be higher. The higher the back-to-source rate of the edge node, the more write operations on the disk of the edge node will be, resulting in the disk of the edge node The lower the efficiency of read operations, the lower the stability of the entire CDN system

Abstract

The embodiment of the invention discloses a method and a device for distributing edge nodes. The method and the device are applied to a dispatcher in a content distribution network system. The content distribution network system comprises at least one edge node and the dispatcher. The method comprises the following steps of receiving a target request sent by a target user, wherein the target request at least comprises identification information of data requested by the target user; distributing one edge node with source return rate lower than a preset first threshold value to the target user. The method disclosed by the embodiment has the advantages that the source return rate of the edge node distributed to the user is lower; compared with the edge node with higher source return rate, the writing operation of a magnetic disc of the edge node with low source return rate is relatively less, the reading operation efficiency is relatively higher, and the stability of the whole content distribution network system is further guaranteed.

Description

technical field [0001] The present invention relates to the technical field of content distribution networks, and in particular, to an edge node distribution method and device. Background technique [0002] In recent years, with the rapid development of Internet technology, the demand for users to visit major websites is increasing day by day. In order to improve the access response speed, enable users to obtain the requested content faster, and solve the state of network congestion, CDN (Content delivery network, content delivery network) plays an important role. [0003] In a CDN system, back-to-source is an important technology. Back-to-source refers to first assigning an edge node to the user, and the user requests the required data from the edge node; if the request is not available (that is, there is no data required by the user in the edge node), the edge node determines that there is stored data required by the user. The edge node of the data requests the data requ...
