What is outbound CN2 GIA? What is a return CN2 GIA? What is a bidirectional CN2 GIA?

What is CN2 GIA has been introduced on this site before: "Introduction to the concept of 163 backbone network / CN2 GT / CN2 GIA route". Some people have just understood the concept of CN2 GIA and may not know what outbound CN2 GIA is. What is a return CN2 GIA, what is a two-way CN2 GIA, and how should I choose among these VPS routes? This article will give you a detailed popular science.

1. Introduction to the concept of CN2 GIA

Before understanding the differences between outbound CN2 GIA, return CN2 GIA and two-way CN2 GIA, you must first understand what CN2 GIA is. For details, please refer to this tutorial:

• "Introduction to the 163 Backbone Network/CN2 GT/CN2 GIA Route Concept".

Some merchants may directly write CN2 when introducing the route, without specifying whether it is CN2 GIA or CN2 GT, such as Dutch CN2, American CN2, Korean CN2, etc. In general, it may be CN2 GT. Because if it is CN2 GIA, it will be said that it is the best CN2 GIA route in Telecom CN2. We need to pay attention to this when choosing a suitable VPS.

2. Outbound/return/two-way CN2 GIA introduction

In fact, the meanings of these three are quite clear. After you understand what CN2 GIA is, these three words have their literal meaning:

• Outbound journey CN2 GIA: Take the CN2 GIA route for the outbound journey. The so-called outbound journey is from the local to the VPS
• Return to CN2 GIA: Take the CN2 GIA route for the return trip. The so-called return trip is from the VPS to the local computer
• Two-way CN2 GIA: Both the outbound and return journeys use CN2 GIA, so it can also be called two-way CN2 GIA

** Some people have suggested that there is another term called "full CN2 GIA". It is not clear whether this whole journey is the whole journey to the destination, the whole journey back, or the whole journey back and forth, so in this case it is still difficult to find out. The merchant asked clearly.

Comparing these three CN2 GIA routes, the two-way CN2 GIA is undoubtedly the best, but when comparing the outbound CN2 GIA and the return CN2 GIA, which one is better? In fact, this is very clear. Just imagine when we use VPS, are we more likely to transfer data from the local to the VPS, or download data from the VPS to the local? If it is used for building a website, 99% of the cases are to transfer data from the VPS to the local, so if there is only one-way CN2 GIA, the return CN2 GIA is more important than the outbound CN2 GIA.
