Technical Field

the present invention relates to the technical field of content distribution networks, and in particular, to a content distribution method, device and system for a content distribution network.

Background

With the rapid development of the internet and the unified trend of markets such as global commodity service and the like being more and more obvious, the demand that various internet sites need to be rapidly accessed by global or whole-Network users is more and more strong, and a Content Delivery Network (CDN) service provides internet bottom layer technical support for such scenes.

For most users, the CDN will provide an available site as a source site, and after a site that needs acceleration accesses the CDN service, a user requests to access the CDN node, and if the cache is not hit, the user returns to the source site of the user, obtains content, and caches the content at the CDN node. The mode is influenced by factors such as site service forms, CDN cache strategies, multi-tenant cache resource competition and the like, and still may bring very large bandwidth cost to the user source station. Therefore, the CDN side provides Object Storage Service (OSS) Storage Service instead of the user source station function, and is also favored by many CDN users.

as shown in fig. 1, in a scenario where an OSS storage service is provided on a CDN side, a CDN user generally uploads new content to the OSS storage service periodically, however, an OSS is generally deployed centrally and takes over the task of uploading a large amount of user content, and the uploading time may be long, so that timely overall network delivery of new content on a site is affected.

First, some terms or terms appearing in the description of the embodiments of the present invention are applicable to the following explanations:

The CDN is called a Content Delivery Network, i.e., a Content Delivery Network. The basic idea is to avoid bottlenecks and links possibly influencing data transmission speed and stability on the Internet as far as possible, so that content transmission is faster and more stable. By placing node servers at various positions of the network to form a layer of intelligent virtual network on the basis of the existing internet, the CDN system can redirect the request of a user to a service node closest to the user in real time according to network flow, connection of each node, load condition, distance to the user, response time and other comprehensive information. The method aims to enable the user to obtain the required content nearby, solve the problem of congestion of the Internet network and improve the response speed of the user for accessing the website.

The Object Storage Service (OSS) is a cloud Storage Service with high volume, safety, low cost and high reliability. The user can upload and download data at any time, at any place, on any internet device. Based on the OSS, the user can build various multimedia sharing websites, network disks, personal and enterprise data backup and other large-scale data-based services.
