First introduce it in one sentence:

CN2 GIA is the highest-level product among CN2 lines: its full name is Globla Internet Access. It is the fastest and lowest-load line connecting mainland China and North America. GIA lines are inserted into CN2 nodes starting with 59.43 in provincial routes in mainland China. (CN2 is the abbreviation of China Telecom's next-generation bearer network). Ordinary CN2 generally represents CN2 GT or CN2 GIS. Transmission in mainland China is carried by Telecom's 163 backbone network. Only the 59.43 route of CN2 is involved in outbound nodes. Under normal circumstances, congestion is still at 163 When the backbone network is congested, the connection effect between CN2 GT (GIS) lines and foreign countries will be poor. CN2 GIA is fully involved in CN2 routing at provincial nodes in mainland China, that is, all provincial-overseas routes use CN2 GIA. Dedicated line, low load, high quality and fast speed!

Here is a graphic introduction to CN2GT:

The picture below is the CN2 GT line in Los Angeles, USA. Taking the IP 156.238.2.1 of the CN2 GT line in the United States as an example, Xiangyang Telecom tracks the IP of CN2 in the United States. In mainland China: the routes from Xiangyang to Guangzhou are all carried by the 163 backbone network of 202.97 , there is no CN2 node of 59.43 in the provincial route. It only enters the CN2 node when going to sea, that is, the route of CN2 node 59.43 appears at the eighth hop in the figure. This is a typical CN2 GT line. -------------------------------------------------------------- －－－－－－－

Then take a look at the graphic introduction of CN2 GIA:

The picture below is the CN2 GIA line in San Jose, USA. Taking the IP 104.233.227.31 of the CN2 GIA line in the United States as an example, Xiangyang Telecom tracks the IP of CN2 GIA in the United States. The itinerary within mainland China is: Xiangyang-Wuhan-Shanghai, that is Hops 5-8 in the figure below are all provincial routes. All provincial routes are carried and transmitted by the CN2 node of 59.43. There is no 163 node of 202.97 in the provincial route. The provincial route until entering the United States is 59.43. It starts and ends after entering the United States. This is a typical CN2 GIA route, please see the picture below
