One Diagram to Understand the Differences Between CN2 GIA, CN2 GT, and Regular Server Routes

Naibabiji Website Building在Purchasing Foreign ServersWhen building a website, you often see providers promoting CN2 routes, CN2 GIA routes. So,What is the difference between CN2 routes and regular routes??Which one is faster?This article will tell you.

Introduction to the Three Types of Routes

Regular Route

This is the regular outbound route. Domestic transmission is carried by China Telecom's 163 backbone network. The provincial/outbound/international backbone nodes all start with 202.97, with no CN2 nodes starting with 59.43 throughout the entire path. On outbound routes, it exhibits congestion and high packet loss rates.

CN2

CN2 stands for China Telecom Next Generation Carrier Network, abbreviated as CNCN, and further abbreviated as CN2.CN2 is further divided into CN2 GIA and CN2 GT:

• CN2 GIA: Full name Global Internet Access. It is the fastest and lowest-load route connecting Mainland China and North America. The GIA route connects to CN2 nodes starting with 59.43 within domestic provincial routing, featuring low load, high quality, fast speed, and high cost.
• CN2 GT: This is the Global Transit (GIS-Global Internet Service) product within China Telecom's CN2 product line. CN2 GT has its own dedicated line to China's international exit, but still uses the 163 exit when entering the domestic network. Provincial/outbound nodes start with 202.97 (202.97 nodes belong to China Telecom's 163 backbone network), and there are 2 to 4 CN2 nodes starting with 59.43 on the international backbone.

Simply put, the differences between the three routes are:

1. CN2 GIA: If the local backbone has a CN2 network, it directly connects via 59.43 and does not go through 202.97.
2. CN2 GT: The exit uses 59.43, but domestically it still uses 202.97.
3. Regular 163 Route: The entire path uses 202.97.
