What do CN2, GIA, CIA, BGP and IPLC mean?

What is CN2 line?

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

CN2 GT: A Global Transit product in CN2 (also known as GIS-Global Internet Service). It has a low level in CN2. Provincial/overseas nodes start with 202.97. There are 2 to 4 international backbone CN2 nodes starting with 59.43. The congestion level on overseas routes is average, slightly higher than that of the 163 backbone network, and more cost-effective than CN2 GIA.

CN2 GIA: CN2 is a product of Global Internet Access, with a high grade. Provincial/overseas/international backbone nodes all start with 59.43, and there are no nodes starting with 202.97. It performs well on overseas routes, with little congestion, and theoretically fast and stable speeds. Of course, the price is also relatively high compared to CN2 GT.

Overall: CN2 GIA is better than CN2 GT

What is a BGP circuit?

BGP (Border Gateway Protocol) is a routing protocol used to connect independent systems on the Internet. It is an enhanced, complete, and scalable protocol developed by the Internet Engineering Task Force. A computer room that uses the BGP solution to achieve dual-line or multi-line interconnection is called a BGP computer room. We generally call BGP servers multi-line.

To put it simply: there are many ISP bandwidth providers in the computer room, which can intelligently switch to provide you with the best lines. So the characteristic is global. If your user base is global, using BGP is definitely a wise choice.

What is the CIA line?

The CIA line is a CN2+163 mixed line.

163 combined with CN2 GIA is a solution adopted by very few ISPs. As we mentioned above, CN2 GIA has a very small backbone network, which can easily be interrupted by attacks. Therefore, we provide 163 IN to ensure that customers' services will not be interrupted due to attacks (the cost of large-volume attacks is too high, and bandwidth is used to resist them, so 100G 4134 bandwidth is connected to solve the traffic in the direction of China), and then let the OUT direction go to CN2 GIA to provide good access quality. 163 and overseas operators' large-capacity networks provide traffic cleaning in the front end, and CN2 GIA guarantees service quality when returning to China. This is basically the best configuration solution at present, without a doubt. This feature is still that the price of GIA bandwidth is too high and there will be no cheap products.

What is IPLC?

IPLC dedicated line is an international private leased line. The essence is a point-to-point intranet. The entrance to the network is in the country, so it will not be affected by international links, there is no need to go through the national firewall, and the IP address availability rate is high. Will not be blocked by the wall. Exporting abroad, you can access any website that is not accessible in China. Because it uses the intranet, it is not affected by network fluctuations. Latency to foreign countries is generally low. So the price is very expensive, but the speed is fast and the latency is very low.

The most comprehensive network line knowledge: the differences and connections between IPLC dedicated lines, CN2, BGP, CIA and ordinary lines

First, let's introduce what is IPLC dedicated line?

IPLC dedicated line is an international private leased line. The essence is a point-to-point intranet. The entrance to the network is in the country, so it will not be affected by international links, there is no need to go through the national firewall, and the IP address availability rate is high. Will not be blocked by the wall. Exporting abroad, you can access any website that is not accessible in China. Because it uses the intranet, it is not affected by network fluctuations. Latency to foreign countries is generally low. So the price is definitely expensive, but the speed is fast and the latency is very low.

Then let me introduce what CN2 line is

CN2 stands for China Telecom Next Carrier Network, abbreviated as CNCN, further abbreviated as CN2, and is divided into cn2 gia and cn2 gt

CN2 GT: A Global Transit product in CN2 (also known as GIS-Global Internet Service). It has a low level in CN2. Provincial/overseas nodes start with 202.97. There are 2 to 4 international backbone CN2 nodes starting with 59.43. The congestion level on overseas routes is average, slightly higher than that of the 163 backbone network, and more cost-effective than CN2 GIA.

CN2 GIA: CN2 is a product of Global Internet Access, with the highest level. Provincial/overseas/international backbone nodes all start with 59.43, and there are no nodes starting with 202.97. It performs best on overseas routes, with very little congestion and theoretically the fastest and most stable speed. Of course, the price is also relatively higher than CN2 GT.

In general: CN2 GIA is better than CN2 GT. For more information about CN2 lines, please refer to: CN2 Line Popularization

Next, let me introduce the BGP line.

BGP (Border Gateway Protocol) is a routing protocol used to connect independent systems on the Internet. It is an enhanced, complete, and scalable protocol developed by the Internet Engineering Task Force. A computer room that uses the BGP solution to achieve dual-line or multi-line interconnection is called a BGP computer room. BGP server is generally called multi-line

To put it simply: there are many ISP bandwidth providers in the computer room, which can intelligently switch to the best line for you users. So the characteristic is global. If your user base is global, using BGP is definitely the wisest choice.

Finally, let’s explain what the CIA line is?

The CIA line is a cn2+163 mixed line.

163 combined with CN2 GIA is a solution adopted by very few ISPs. As we mentioned above, CN2 GIA has a very small backbone network, which can easily be interrupted by attacks. Therefore, we provide 163 IN to ensure that customers' services will not be interrupted due to attacks (the cost of large-volume attacks is too high, and bandwidth is used to resist them, so 100G 4134 bandwidth is connected to solve the traffic in the direction of China), and then let the OUT direction go to CN2 GIA to provide the best access quality. 163 and overseas operators' large-capacity networks provide traffic cleaning in the front end, and CN2 GIA guarantees service quality when returning to China. This is basically the best configuration solution at present, without a doubt. This feature is still that the price of GIA bandwidth is too high and there will be no cheap products.
