I received an email description from the merchant above. Please forward it to us novices. Understand what is a round trip? One way?

CN2, the full name is Chinatelecom Next Carrier Network (CNCN). Currently, there are generally three types of bearer networks for international telecommunications exports, including the traditional 163 backbone network, CN2 GT lines and CN2 GIA lines: < /p>

CN2 GIA line: GIA is the abbreviation of Global Internet Access. CN2 GIA is naturally a type of CN2 line and is a high-end product among CN2 lines. It has the highest level in CN2 and uses 59.43 high-speed cable for the entire journey and return journey. CN2GIA lines are generally relatively stable, fast, and have low packet loss rates.

The CN2 GIA line is a high-speed line launched by China Telecom. It is divided into two-way CN2 GIA and one-way CN2 GIA. One-way refers to a high-speed line for domestic visits to foreign countries and an ordinary line for the return trip. The two-way CN2 GIA is a high-speed line that takes both the outbound and return journeys, so here we at OVZH.COM use the two-way CN2 GIA, which is the full CN2 GIA high-end line.

We know that routing is two-way, going and returning. One-way CN2 GIA means that only one side goes through CN2 GIA, and the other side goes through other networks. There may be two situations

The outbound journey is CN2 GIA, and the return journey is ChinaNet. This situation is common, mainly because many host companies use it as a gimmick to advertise CN2 GIA. The outbound journey of CN2 GIA can be easily evaluated. But in fact, the outbound CN2 GIA does not have much effect. It only temporarily reduces the outgoing delay, because we know that in the network access situation of ordinary users, the return traffic is more profitable than the outbound traffic, and the one-way CN2 GIA is cheaper. Some, because they use less traffic, are still a bit more expensive than pure ChinaNet. They feel a bit tasteless, and it is a pity to abandon them and tasteless.

This is also a combined one-way CN2 GIA. In terms of speed and price, the pure CN2 network is relatively fragile. The 163 network has a large capacity and can withstand attacks from mainland China. Generally, two-way CN2 GIA is more expensive than one-way CN2 GIA because the return volume accounts for the majority of Internet services. And if you need speed, of course the best one is two-way.

The first thing to determine is that the traditional 163 backbone network and CN2 Telecom direct lines (CN2 GT and CN2 GIA) are all networks for Telecom. If it is a triple network CN2, it means that China Mobile and China Unicom will also use Telecom's CN2. Lines, usually jump to China Telecom's CN2 line in China, and then take the international exit, so as to enjoy the CN2 line.

Traditional 163 backbone network: This is the most common and common line, also called ChinaNet (AS4134). There is no line optimized for telecom users. This type of bearer network is generally used (full range 202.97), because the people who use it There are many, and the lines are not optimized, so there will be line lags and high packet loss rates during the evening peak hours.
