Problems solved by technology

When the live stream of each video protocol stack is connected to the CDN network, it needs to be uniformly managed and configured on the CDN network, and all live streams need to be continuously transmitted on the access layer device and the backbone network relay layer device. Therefore, not only the complexity of service configuration will double with the increase of terminal types, but also the traffic between backbone networks will be doubled.

Embodiment Construction

[0022] Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided for more thorough understanding of the present disclosure, and to fully convey the scope of the present disclosure to those skilled in the art.

[0023] figure 1 A schematic structural diagram of a CDN data distribution system in the prior art is shown. Such as figure 1 As shown, the live stream of one protocol from a single live source is pre-encoded and converted into multiple live streams of different video protocol stacks through multiple transcoders, and then respectively connected to the access layer equipment of the CDN network platform. After being accelerated by ...

Abstract

The invention discloses a data distribution system based on a CDN (content distribution network). The data distribution system comprises an access layer device, one or more relay layer devices and one or more margin layer distribution devices, wherein the access layer device is suitable for receiving a broadcasting data packet from a broadcasting source and converting the broadcasting data packet to a transmission data packet of a predetermined format; each relay layer device is suitable for performing relay transmission on the transmission data packet of the predetermined format converted by the access layer device through a uniform transmission protocol; each margin layer distribution device is suitable for receiving the transmission data packet of the predetermined format after relay transmission performed by each relay layer device and converting the transmission data packet of the predetermined format to a data packet of a terminal broadcasting protocol according to a terminal request and distributing the data packet to the terminal. The invention also provides a data distribution method based on the CDN. By utilizing the data distribution system and the data distribution method, the reliability of live stream can be greatly improved, and the transmission efficiency among backbone networks also can be greatly improved.

Description

technical field [0001] The present invention relates to the field of Internet data transmission, in particular to a data distribution system based on a CDN network (the full name is Content Delivery Network, ie a content distribution network) and a data distribution method based on the CDN network. Background technique [0002] Currently, large amounts of data can be transmitted over the Internet. Internet TV, Internet radio, etc. have become very common. For example, for the transmission of Internet TV broadcast content, terminals that support the corresponding video protocol stack, such as IPAD and IPHONE that support HLS / TS protocol, PC terminals that support RTMP / FLV or HTTP / FLV, and RTSP / TS or HTTP / TS Protocol smart set-top boxes, and Android mobile terminals that support HTTP / TS or HLS / TS protocols, by sending protocol requests corresponding to live programs, after being scheduled by the CDN network platform, the corresponding live streams are obtained and played at t...
