Friends who often deal with virtual hosts or independent servers basically come into contact with a concept, that is, CN2, a more comprehensive introduction to the CN2 line.

　　CN2 GT we are also called one -way CN2, CN2 GIA can be understood as two -way CN2. At present, there are two lines of telecommunications in our country to access the global Internet, that is, 163 backbone network and CN2. The exporting international bandwidth is CN2, and the loop walks 163 backbone network is CN1. Let's introduce the 163 backbone network and CN2.

　　1. 163 Backbone Network is connected to AS4134 bandwidth, and the CN2 line is connected to AS4809 bandwidth;

　　2. Route Figure (MTR) test, we can know that the 163 backbone network is a route starting with the 202.97 IP address, and the CN2 line is the route of 59.43 IP address;

　　3. 163 The international export bandwidth of the backbone network is not easy to block, the price is cheap, while the overall bandwidth capacity of the CN2 line is small and the cost is high.

　　After understanding the 163 backbone network and CN2, you can also know the differences and advantages and disadvantages of CN2 GT and CN2 GIA.

　　CN2 GT, Global Transit, international exports generally take 59.43 lines. CN2 GIA is also directly in China to take international export bandwidth. But there are more obvious differences between the two back lines. CN2 GIA still takes 59.43 lines throughout the process, while CNW GT will take the 202.97 line in China. In this way, CN2 GIA will save a lot of time than the CN2 GT, and the loading time of the host or independent server will be much faster.

　　Compared with the advantages of the two:

　　GIA has a faster speed and low load, which is the best quality in the telecommunications network.

　　The disadvantages of the two:

　　The price of GIA is relatively expensive, and the market will basically be about 2-3 times more expensive than GT, and the GIA export bandwidth resources are small. If some uncontrollable factors such as being attacked, it is likely to affect the stability of the entire GIA line. sex.

　　When we rent an American host or an independent server, we can distinguish between the differences between the two. It is the most important thing to choose a reasonable product. Friends who want to build a station can choose the American host or independent server, which is stable at high speed.
