Abstract
The invention discloses a video access method and system, and a video agent of a CDN server and relates to the field of mobile internet. The method includes: the video agent of the CDN server receives a video access request which is sent by a user through a browser, wherein the video access request carries a video label which includes a CDN attribute which indicates the address of the CDN server and a source-address SRC attribute which indicates a video source address and then the video access request addresses to the CDN server according to the CDN server address indicated by the CDN attribute; and the video agent judges whether a video corresponding to the video source address is stored in the CDN server; if the video corresponding to the video source address is stored in the CDN server, the video agent distributes the video, which is corresponding to the video source address and stored in the CDN server, to the browser. The video access method and system, and the video agent of the CDN server enable users to obtain the content of a corresponding video without using a core exchange network every time so that nearest distribution of the content of the video is realized and video traffic pressure of the core exchange network is relieved.
Description
Technical field
The present invention relates to mobile Internet field, particularly the video agency of a kind of video access method and system, content distributing network (Content Delivery Network is called for short CDN) server.
Background technology
Along with the fast development of mobile Internet application and the extensive use of Video service, there is a large amount of Video Applications site for services, the multitude of video that these websites provide transmits in network, and core switching network is caused to very large flow pressure.
Most users carries out video access by browser at present, but the HTML version 5(Hypertext Markup Language of browser, be called for short HTML5) video tab (, VIDEO label) mainly support 3 kinds of conventional video formats, the first, with the Ogg file of Theora Video coding and Vorbis audio coding; The second,
With H.264 Video coding and the Advanced Audio Coding MPEG4 file of (being called for short AAC); The third, with the WebM file of VP8 Video coding and Vorbis audio coding.HTML5 still can not support the video of more code/decode format at present.
The VIDEO label of HTML5 is due to its characteristic limitations at present, and the coding and decoding video form that can support is limited, and user, when by browser access video, cannot use the open function of ability of CDN, causes core switching network video flow pressure large.
