Problems solved by technology

However, when the scale of CDN increases and the number of CPs increases, since all nodes need to be configured, the static configuration method not only leads to a large workload, but also is prone to errors. At the same time, when the content routing changes, the content routing information cannot dynamic update

Abstract

The invention discloses a content routing distribution method, a content distribution network node and a system. The method includes: the upper-level CDN node generates content routing information in response to receiving new content data provided by the content-providing CP entity, and the content routing information includes CP entity identification, port identification, and link cost; the upper-level CDN node identifies whether there is a lower-level CDN node ; In response to the presence of a lower-level CDN node, the upper-level CDN node sends a routing incremental update message to the lower-level CDN node to include content routing information; the lower-level CDN node updates the port identifier and link cost value in the received content routing information; the lower-level CDN node The node is an upper-level CDN node, and the operation of identifying whether there is a lower-level CDN node is performed again. Through the technical solution provided by the invention, nodes in the CDN can automatically obtain content routing information, simplifying the flow of content routing configuration.

Description

technical field [0001] The invention relates to the field of the Internet, in particular to a content routing distribution method, a content distribution network node and a system. Background technique [0002] In recent years, the content delivery network (Content Delivery Network, CDN) is to send content including video, audio, web pages, etc. to the network closest to the user by adding a new network architecture to the existing IP bearer network. "Edge", so that users can get the content they need nearby, so as to solve the optimization of network traffic conditions and improve the response speed of users visiting websites. CDN can solve the problem of slow user access response speed caused by low backbone network bandwidth, large user access volume, and uneven network distribution. [0003] The basic principle of CDN is that when a user needs to use a content, the user requests the content from the nearest CDN edge node through the terminal. When the content does not e...
