Method and system for CDN back-to-origin service

Abstract

The invention provides a CDN back-to-source service method and system, and the CDN back-to-source service method and system are suitable for being used in the technical field of communication. The method includes the steps that a content request carrying the content identification of the content on the content providing network side is received from a client; the content identification is parsed from the content request, and the back-to-source address query interface of the content providing network is called according to the content identification to inquire for the back-to-source address of the content, and the back-to-source operation is executed according to the back-to-source address. By means of the CDN back-to-source service method and system, a network operator can be helped to introduce a plurality of CDN software and device providers, meanwhile, the distribution efficiency of the content among systems between a content provider and the network operator is improved, the risk of reforming the existing system by the network operator is lowered, and the medium resource file transmission can be better finished.

Description

technical field [0001] The present invention relates to the technical field of communication, and in particular to a method and system for CDN back-to-origin service. Background technique [0002] OTT TV (Over The Top TV) refers to video services based on the open Internet, and the terminals can be TVs, computers, set-top boxes, PADs, smart phones, etc. B2B (Business-to-business e-commerce model, business-to-business e-commerce model) refers to the marketing relationship between business and business. Response, provide customers with better services, thereby promoting the business development of enterprises. B2B OTT TV is a TV business carried out on the Internet in cooperation between ICP (Internet Content Provider, Internet Content Provider) and network operators. According to the characteristics of the Internet, the system adopts a variety of Internet video technologies such as multi-bit rate network adaptation and video slicing. The entire Internet TV system is compos...

AI Technical Summary

Problems solved by technology

At present, the dynamic bit rate technology represented by HLS (HTTP Live streaming, HTTP-based streaming media) has gradually replaced the existing on-demand technology. Under the HLS technical system, the content of each bit rate of a video will be cut into Hundreds of video file slices. In this case, if the existing injection mode is continued to realize the system connection between content providers and network operators, the complexity of connection, system stability and timeliness of content online There are big problems, which have a great impact on meeting the content needs of users and the business development of operators

Therefore, it is very necessary to use the back-to-source mode to replace the existing injection mode on the newly introduced CDN nodes, but if the newly introduced CDN nodes use the back-to-source mode to the existing CDN of the network operator, the following problems will arise : The existing CDN belongs to the online service (providing services for users) system, and the provision of back-to-source service will inevitably affect the streaming service quality provided for users; It is very difficult and risky to transform the system; because of the protection of historical investment, the existing CDN cannot be abandoned, and the existing CDN and the new CDN are required to coexist and develop business at the same time

[0005] In summary, there are obviously inconveniences and defects in the actual use of the existing technology, so it is necessary to improve
