So, does the CN2 optimized route optimize China Mobile and China Unicom routes? Should China Unicom and China Mobile users choose the CN2 GIA route? What does the triple network CN2 GIA also mean? This article will introduce some concepts related to CN2 GIA to beginners.

CN2, the full name is China Telecom Next Carrier Network (CNCN), and if you add the abbreviation of CNCN, you get CN2. For an introduction to the concept of CN2 and how to distinguish between 163 backbone network/CN2 GT/CN2 GIA, you can refer to the previous related introduction:

2. China Unicom CN2 GIA and China Mobile CN2 GIA

Since CN2 is China Telecom’s bearer network, is CN2 optimized for China Unicom and China Mobile? I believe many people have seen the words China Unicom CN2 GIA, China Mobile CN2 GIA, and Triple Network CN2 GIA in some VPS introduction articles, so let me introduce these three terms first:

• China Unicom CN2 GIA: The China Unicom route is transferred from China Unicom to China Telecom in mainland China, and then goes abroad via Telecom CN2 GIA, and vice versa for the return route
• Mobile CN2 GIA: The China Unicom route is transferred from China Unicom to China Telecom in mainland China, and then goes abroad via Telecom CN2 GIA, and vice versa for the return route
• Three networks CN2 GIA: China Mobile, China Unicom, and China Telecom all use China Telecom CN2 GIA to complete international jumps

Here we take China Unicom as an example to illustrate Unicom CN2 GIA. From the figure, you can see that the hop number 8-9 is the jump from China Unicom to China Telecom, which jumps directly to the Telecom CN2 GIA node in mainland China. The hop number 10-11 is the international jump through Telecom CN2 GIA. Jump directly from Guangzhou, China to California, USA:

3. Do China Mobile and China Unicom require CN2 GIA

Currently, Hong Kong’s CN2 GIA route can only require two-way CN2 GIA from China Telecom. China Mobile and China Unicom can be directly connected. This is also the route for most Hong Kong CN2 GIA VPS. It can be said to be the fastest and most suitable for website building that can be purchased. Hong Kong VPS has been sorted out for everyone in the "Hong Kong CN2 GIA VPS Sorting Recommendations".

For American CN2 GIA and European CN2 GIA, China Mobile CN2 GIA and China Unicom CN2 GIA are still much better than their respective direct routes. Here is a comparison of the speed test and packet loss rate test of the CN2 GIA and China Mobile/China Unicom direct connection routes as an example:

1. Three networks CN2 GIA speed test

2. China Unicom and China Mobile direct connection speed test

3. Three networks CN2 GIA packet loss rate test

4. China Unicom and China Mobile direct connection packet loss rate test

Judging from the speed and packet loss rate comparison results, China Telecom CN2 GIA is optimized for China Mobile and China Unicom. China Mobile CN2 GIA is much faster than China Mobile’s direct connection route. Another major advantage of CN2 GIA is that it merges with three networks The packet loss rate is much lower than that of direct non-CN2 GIA routes.
