CDN License – B12 Content Delivery Network Services

CDN License – B12 Content Delivery Network Services

Chinese Name: CDN 许可证 – B12内容分发网络业务


The B12 License is a license under the VATS (Value-Added Telecommunications Services) licensing scheme authorizing a business to provide network acceleration services for video websites, enterprise portal websites, personal websites, shopping websites, enterprise websites or data information.


The B12 license is defined in Announcement of the Ministry of Industry and Information Technology on Promulgating the Classification Catalogue of Telecommunication Services (2015) as follows:

“Content delivery network (“CDN”) services refer to the available services of providing users with the scatter storage and cache memory of contents, by utilizing the node server groups located in different regions to constitute the traffic distribution management network platforms, and delivering such contents to the rapid and stable cache servers on the basis of the dynamic traffic and load status of networks so as to enhance the response speed and services of users’ access to such contents.”

Who needs one?

The B12 license is required for businesses providing network acceleration services for video websites, enterprise portal websites, personal websites, shopping websites, enterprise websites or data information.

Typical network acceleration service use cases include:

1. Acceleration of a website

This is common in portal and e-commerce websites such as NetEase, Taobao, and others. Such sites frequently have a large number of static content files (text, images, and so on) that can be accelerated by CDN, significantly improving page response time and user experience.

2. Acceleration of file downloads

CDNs play an important role in accelerating file downloads. This is common in the distribution of software patch packages as well as the download of game installation packages. Such files are large in size, and the download process will easily put a strain on the origin site’s bandwidth, affecting its performance. The use of a CDN alleviates this pressure and significantly improves download speed from the client’s end.

3. Media streaming acceleration

This type of acceleration directs streaming media content to the edge node closest to the user, allowing users to access the content from the closest edge location, improving video transmission quality, shortening access time, and reducing backbone network traffic. Streaming media acceleration supports both live and on-demand video streaming. It is suitable for a variety of audio and video websites and applications, including Douyin, iQiyi, and others.

4. Acceleration across the site

This is mostly used on sites with a lot of dynamic content. It boosts network performance by using dynamic acceleration technologies like intelligent routing and protocol optimization.

5. Secure Data Encryption

Methods of encryption are constantly evolving. Trusted CDN providers use the most recent SSL certificates and data security methods without interfering with their customers’ operations. This is commonly used in e-commerce and fintech.
