What is the difference between CN2 GIA and CN2 GT? How should I choose?

Telecom CN2 is also divided into Telecom CN2 GT and Telecom CN2 GIA. Some merchants only indicate the Telecom CN2 route when describing the route. At this time, we need to figure out whether it is CN2 GT or CN2 GIA. This article will introduce it. The difference between CN2 GIA and CN2 GT and how to choose.

1. Introduction to Telecom CN2

Telecom CN2 is China Telecom Next Carrier Network (CNCN). CN2 was launched by Telecom as a "premium network project". The route quality is definitely better than the traditional 163 backbone network.

When we choose Telecom’s CN2 route, we often see the terms CN2 GT or CN2 GIA:

2. The difference between CN2 GIA and CN2 GT

In fact, the difference between when we use CN2 GIA and CN2 GT is very obvious. The speed of CN2 GIA is much more stable than that of CN2 GT, especially at night. During the evening peak period, the packet loss of CN2 GT is very serious. This is why we were building a VPS website before. In the recommendation, it is recommended that everyone buy CN2 GIA instead of CN2 GT.

The difference between CN2 GIA and CN2 GT is also obvious, that is, whether the whole journey takes the 59.43 high-speed node. The more detailed differentiation steps are (detailed introduction: "163 Backbone Network / CN2 GT / CN2 GIA Route Concept Introduction and VPS Service Provider Recommendation" 》):

• Both CN2 GT and CN2 GIA ensure that transmission between countries is carried out on the CN2 backbone network (node ​​59.43), that is, international exports take 59.43;
• The provincial export of CN2 GT is 202.97 nodes, and it will only go to 59.43 when exporting internationally. For example, from Nanjing Telecom->Shanghai Telecom, CN2 GT is 202.97, while CN2 GIA has gone to 59.43;
• If the CN2 GIA route has a CN2 node in the province, it will directly access the CN2 node. For example, starting from Nantong, Jiangsu, there is a CN2 node (Nanjing, Jiangsu) in this province, so the CN2 GIA route directly connects to the CN2 node (59.43) in Nanjing, Jiangsu, and then exits from Shanghai;
• If the CN2 GIA route does not have a CN2 node in the province, it will connect to the nearest node 202.97 in Beijing, Shanghai and Guangzhou, and then connect to the node 59.43 there. For example, Anhui Wuhu Telecom first accesses Shanghai 202.97, then 59.43, and finally exports.

3. Suggestions for choosing CN2 GIA and CN2 GT

Let me talk about the conclusion first: Nowadays, CN2 GT is becoming more and more crowded. It is recommended that everyone choose CN2 GIA. Although it will be more expensive, it is worth the money. CN2 GIA is much better than CN2 GT.

With the increasing pressure on export bandwidth, CN2 GT can only perform the same as the ordinary 163 route during the evening peak period, without the characteristics of fast speed and stable route of "premium network projects". Previously, this site shared the evaluation of Bricklayer DC3 CN2 GT data center. In addition to the good speed of China Unicom, the packet loss of China Telecom and China Mobile was very serious: "Bricklayer DC3 CN2 GT Evaluation: Speed, Delay, Packet Loss Rate and Routing Test" < /p>
