We should know that China's internet is actually "split between the north and the South", the Yangtze River south of the network is controlled by China Telecom, the north of the Yangtze River is the Chinese netcom (now merged into China Unicom) master.
This creates a problem with telecommunications-connected http://www.aliyun.com/zixun/aggregation/14840.html "> virtual hosts that use Netcom's broadband access, access speed will be very slow, and vice versa." Such a line machine for small sites, but for businesses and large sites, is undoubtedly fatal. In response to the low speed of exchange visits, stability, and low transmission quality of China Netcom, some space providers have launched a dual-line virtual host, that is, a server can access both telecom and Netcom lines.
This connection method is better than CDN Accelerator, it can avoid the problem that the website and CDN Mirror data are not synchronized. can also solve the site line and the visitor line is not the same result of slow access problems. For example, the Ndns Intelligent analysis technology, intelligent matching visitors line, speed up access, ease the internet "traffic jam" phenomenon. So far, intelligent dual-line access is the most perfect solution.
