Abstract

The invention discloses a CDN transparent transmission method adopting an optimized structure, and belongs to the technical field of CDNs. Upgraded CDN lower-level nodes are adopted; when index files and video files pushed by CDN upper-level nodes are received, the index files are upgraded; URL addresses of all video clips in the index files are replaced with addresses of the CDN lower-level nodes, and therefore when requesting each video clip, a client side directly requests services from the CDN lower-level nodes round an SLB. According to the optimized structure, loads of the SLB are reduced, the CDN scheduling policy is optimized, and the user experience is ensured.

Description

technical field

[0001] The invention relates to the technical field of CDN, in particular to a CDN transparent transmission method adopting an optimized structure. Background technique

[0002] The simplest method of CDN transmission adaptive streaming media - CDN transparent transmission method, is to simply divide the CDN into 3 parts: upper-level CDN, lower-level CDN and server load balancing (SLB, Server Load Balancing). Among them, the upper-level CDN refers to the central node, which imports the index files and slice files generated by the server components, and distributes these contents to the lower-level CDN nodes. The URL address obtained by the user on the web page usually points to the SLB, and the SLB redirects the user to the most suitable lower-level CDN node based on comprehensive information such as the user's IP address, CDN node load, and network traffic.

[0003] The principle of the traditional CDN transparent transmission method is to regard each video...
