2, the current site is facing the main problems
In the early days of China's Internet construction, China's telecom operators, for reasons such as planning and investment, focused on key cities or regions, and the backbone of the Internet was very narrow in some two-tier cities or more remote areas. The bandwidth resources in these areas appear very tense, internet users experience a poor internet, open a site will take a long time, or even can not open the site. (Computer science)

According to previous experience of Internet construction and application, the application of Internet is always ahead of the construction of infrastructure, the technology of the website from the original static webpage, to later dynamic page, and now more popular some interactive, flash or streaming media technology, the demand for the bandwidth is higher, And the lag of backbone network infrastructure and the high cost of the last kilometer have seriously affected the application and popularization of new technology of website. On the one hand, the Web site is eager for new technology to bring new revenue to the business, on the other hand, Internet users want to enjoy the new business model, work life learning convenience and other more rich network applications. But in fact, the traditional network structure and the content of the site to publish the way to restrict all this.
Moreover, with China Telecom North-South Division, the backbone of the Internet network has also been divided into the north, the Chinese Netcom, the South Telecom. Now a lot of netizens reflect, some frequently visit the website speed becomes very slow, even cannot visit. 10 northern provinces and regions of Internet users visit China Netcom IDC's website will be very fast, and visit the Chinese telecom IDC website, feel very slow, or even open. In addition to the difficulties of the North-South exchange of visits, site owners or managers of the site management and maintenance has become unusually difficult, the page update to upload to the server takes a long time, the site is not timely updates. The emergence of these problems has greatly reduced the domestic web site response speed, information service quality and network promotion effect. The main reason for this problem is the separation of China Telecom, the two major telecommunications operators in the interconnection between the major differences, so there has been a bottleneck in the routing of North-South exchange, although the Ministry of Information industry is trying to coordinate, but it is estimated that over a long period of time, the north-South exchange of the problem will be slow.
The importance of E-commerce sites needless to be further. The existence of these problems directly affects the release and timely delivery of product information of E-commerce website, making it difficult or impossible to carry out the transaction, which seriously affects the development of E-commerce business.

3. Solutions
In view of the lag of China's Internet infrastructure, the emergence of new applications and the problems of North-South interoperability, an intelligent content distribution technology and solutions came into being, this is the CDN solution.
1) The role of CDN:
· CDN can improve the performance and reliability of the site, allowing the network content to be located closest to the end user and minimizing the load and transmission latency of the source server.
• It eliminates internet congestion, allows rich content to be delivered efficiently, and makes it possible to deliver video and other rich content without reducing site performance.
· The CDN solution optimizes the bandwidth of expensive sites and eliminates the need for content across more expensive networks.
• Protecting the source server
2 The revenue of the website:
• Improved trading success rates and customer satisfaction-proactively sending web content that is often accessed to a CDN node that is closer to the user can shorten the response time of the site, eliminate the "server not found" error, and enable the transaction to be completed successfully.
• Increase user loyalty.
• The site does not need to invest expensive types of servers, set up a branch site.
• Web site only need to maintain content, do not need to consider traffic problems, improve the bandwidth utilization rate. Both cost saving and efficiency improvement.
• Web site can improve the new business, and provide better service quality, improve the competitive power.
• Strengthen control over web resources-enhanced management capabilities optimize the network content provider's high-priority network content, application software, and business plans to maximize their benefits. Improve the efficiency.
