When we choose ECS, do we see that there are mainly three backbone networks, CN2 GIA, CN2 GT and 163? What's the difference between the three networks?
163 backbone
This is the most common line. All the backbone nodes start with 202.97. Because of the large number of users and low degree of optimization, the overseas lines are congested, slow, and high packet loss rate;
CN2 GT
GT is short for Global Transit, which is a mid tier product in CN2. It has a low level in CN2. There will be nodes beginning with 59.43 and 202.97 on the route to and from China, and 163 backbone and CN2GIA will be used on the route Hybrid lines, due to 163 backbone lines, may cause network congestion in the late peak period, but compared with the traditional 163 backbone network, there are still many improvements;
CN2 GIA
GIA is the abbreviation of Global Internet Access. It is the most high-end product in CN2 at present. It has the highest level in CN2. All the routes go to 59.43 nodes, and there is no 202.97 in the whole route. Therefore, the line is the best and most stable, with few congestion, but the price is also the highest;
Both 163 backbone, CN2GT and CN2 GIA are telecommunication networks. Unicom and Mobile also have their own network lines. The commonly said three network GIA actually refers to the network lines through telecommunications. At present, although the broadband bandwidth of telecommunication networks is the largest, the number of users is also the largest, so the evening peak will also be very congested.
