Content distribution network. The basic idea is to avoid the bottlenecks and links that may affect the speed and stability of data transmission on the Internet, so as to make the content transmission faster and more stable. By placing node servers everywhere in the network to form a layer of intelligent virtual network based on the existing Internet, the CDN system can redirect the user's request to the nearest service node in real time according to the comprehensive information such as network traffic, connection of each node, load status, distance to the user and response time. The purpose is to enable users to access the content they need nearby, solve the congestion problem of Internet network, and improve the response speed of users visiting the site.

What does cdn maintenance work need to do? Enterprises need to pay attention to the daily maintenance of cdn in several aspects.

1. Investment in infrastructure and technology research and development, that is, the quality and number of nodes (so small CDN service providers are naturally at a financial disadvantage). Sensitive to Internet traffic, sensitive to the underlying technology of IP network; more and more dynamic data, how to accelerate for dynamic technology, how to effectively separate dynamic and static, how to automatically identify and distinguish different services, how to schedule traffic intelligently, and so on.

two。 A deep understanding of the business of Internet companies, for games, video, portals, e-commerce and other Internet companies, what are the unique needs of different business types, and how should services and products actually solve problems? how to make customers really feel convenient, practical and efficient.

3. Service awareness, how to continuously improve the efficiency of the background system, how to give customers a really convenient and concise operation interface, how to use bandwidth and other data to count out more valuable information to give feedback, and how to make CDN services relatively transparent, instead of becoming a kind of work pressure on the operation and maintenance department.

4. Data talk, accumulated so much data, what kind of feedback, what kind of summary and induction, can extract what is more valuable to customers, whether you can find the problems of the current system and solve them as soon as possible.

5. Operational experience, experience is very important, the service time of a CDN service provider is very critical, of course, experience is not a simple accumulation of time, should be a continuous summary, continuous improvement process, long really meaningful.

The above is an introduction to the maintenance of cdn.
