Problems solved by technology

Since the playback data contains multiple fragment files, when each fragment file is delivered, a request will be sent to the CDN network separately, so the CDN network needs to process multiple requests, which puts a lot of pressure on the CDN network

Abstract

The invention discloses a content delivery network (CDN)-based transmission system which comprises CDN access layer equipment, CDN transmission layer equipment and edge layer distribution equipment, wherein the CDN access layer equipment is used for receiving play data comprising an index file and fragment files from a play source, streaming the fragment file in the play data and packaging into a play data stream; the CDN transmission layer equipment comprises multiple transmission layers and is used for transmitting the packaged play data stream to the edge layer distribution equipment according to a request from a playing terminal transmitted by the edge layer distribution equipment; the edge layer distribution equipment is used for receiving the play data stream, segmenting the play data stream into fragment files, generating a corresponding index file and distributing the fragment file to the play terminal which transmits the request according to the index file. In addition, the invention also provides a CDN-based transmission method. According to the system and method, the pressure of CDN service can be reduced, the transmission efficiency is improved, and the damage rate of a disc is reduced.

Description

technical field [0001] The present invention relates to the technical field of data transmission in the Internet, in particular to a transmission system and method based on a CDN network (full name is Content Delivery Network, ie content distribution network). Background technique [0002] With the rapid development of Internet technology, more and more network audio and video programs appear, including live and non-live network audio and video programs. Currently, a CDN network platform is usually used to transmit the data of the playback source from the source to the playback terminal. Since the playback data contains multiple fragment files, when each fragment file is delivered, a request will be sent to the CDN network separately, so the CDN network needs to process multiple requests, which puts a lot of pressure on the CDN network. Contents of the invention [0003] In view of the above problems, the present invention is proposed to provide a CDN network-based transm...
