Taking a bricklayer as an example, let’s talk about the difference between CN2 GIA and CN2 GT lines.

Friends often ask what the CN2 line is, and what is the difference between CN2 GT and CN2 GIA. Today, I will simply share what I know. Everyone is welcome to criticize and correct.

First of all, let’s talk about what a CN2 line is. The answer can be found in Baidu Encyclopedia: CN2 is China Telecom’s next-generation bearer network. CN2 is a multi-service bearer network that can support the integration of data, voice, and video services. It is an important link between China Telecom's backbone network and its commercial customers, and will directly determine the quality and flexibility provided by China Telecom. . The full name of the CN2 line is Global Transit, and the abbreviation is CN2 GT. CN2 lines generally use the Telecom 163 backbone network of 202.97 in mainland China. When going abroad, you only use the CN2 lines starting with 59.43.

For example, as shown in the picture, the source of the picture is: Banwagonhost Double Eleven special CN2 line VPS evaluation. This is the Banwagonhost CN2 line. You can see that the last node in the province is in Jiangsu, and the last node IP is 61.160 At first, when I went abroad, the routing node started with 202.93, and then it became the CN2 line that started with 59.43. For convenience, this site generally refers to the CN2 GT line as the CN2 line. CN2 lines generally use the Telecom 163 backhaul network starting with 202.93.

These two pictures are the telecom routes of the CN2 GIA line of Banwagonhost. You can see that the outbound route directly changes to the CN2 line starting with 59.43 at the Shanghai node. The return route also takes the CN2 line 59.43, but it is Returned from Guangzhou. Generally speaking, all CN2 GIA lines at provincial nodes take the route starting with 59.43, and the return route also takes the route starting with 59.43. Only a few outbound routes use 163, and the return journey becomes CN2 GIA. This is the preferred solution to defend against attacks, because under normal circumstances, the outbound journey between China and the United States is very smooth, and the return journey is prone to congestion, so it can be customized to use the backbone for the outbound journey and the return journey. Take CN2 GIA to solve the congestion problem.

Too long and ugly. A simple summary: if you only take the 59.43 route for the outbound trip, it is the CN2 GT line; if you take the 59.43 round trip route, it is the CN2 GIA

Some friends also said that when introducing some lines, they also mentioned what the triple network or China Mobile China Unicom CN2 lines meant. In fact, China Unicom or China Mobile borrowed China Telecom's CN2 lines, some for the outbound trip, some for the return trip, and some for the round trip.

For foreign VPS merchants, some clearly indicate the CN2 GIA line on the product name (such as the CN2 GIA package for bricklayers), and they will always use the CN2 GIA line; some do not clearly indicate the CN2 GIA line. It's just that when a business first attracts Chinese customers (such as anyNode), or suddenly uses the CN2 GIA route (such as cloudcone) to take advantage of the computer room, it's hard to say when it will stop using the CN2 GIA route. The same is true for the CN2 line. For example, the Los Angeles QN computer room used the CN2 line by default two years ago, but it stopped using it this year. Therefore, this site recommends that you distinguish clearly when buying.

The above is the introduction of this website on the difference between CN2 GIA and CN2 GT lines. If you have any questions, please leave a comment below the article.
