What are the meanings of CN2 GIA CIA BGP and IPLC in network circuit science popularization

What is an CN2 line?

CN2 is called the next generation bearer network of China Telecom, English Chinatelecom Next Carrier Network, abbreviated as CNCN, and further abbreviated as CN2, which is divided into CN2 GIA and CN2 GT.

CN2 GT: CN2 is a product of Global Transit (also known as GIS-Global Internet Service), which has a low grade in CN2, with provincial/overseas nodes starting at 202.97 and international backbone nodes having 2 ~ 4 CN2 nodes starting at 59.43. The congestion degree on the overseas route is 1, which is slightly stronger than that of the 163 backbone network, and the cost performance is also higher than that of CN2 GIA.

CN2 GIA: CN2 is a product of Global Internet Access, with high grade. The provincial/overseas/international backbone nodes all start with 59.43, and there is no node beginning with 202.97 in the whole process. It performs well on the overseas route, with little congestion. In theory, the speed is fast and stable. Of course, the price is higher than that of CN2 GT.

Overall: CN2 GIA is superior to CN2 GT

What is an BGP line?

BGP (Border Gateway Protocol, Border Gateway Protocol) is a routing protocol used to connect independent systems on Internet. It is an enhanced, sophisticated and scalable protocol developed by the Internet Engineering Task Force. BGP computer room is called BGP computer room, which adopts BGP scheme to realize double-line interconnection or multi-line interconnection. The BGP server is generally referred to as multiwire.

Simply put: There are many ISP bandwidth providers in the computer room, which can intelligently switch good lines for your users. So the characteristic is global. If your user base is global, using BGP is definitely a wise choice.

What is an CIA line?

CIA line is CN2+163 hybrid line.

163 combined with CN2 GIA, which is a rare scheme adopted by ISP, CN2 GIA We mentioned above have a very small backbone network, It's easy to stop eating because of attack, Therefore, we provide 163 IN to ensure that customers' business will not be interrupted by attacks (high traffic attacks are too costly, They all use bandwidth to resist the lack of proximity, so they access the 4134 bandwidth of 100G to solve the traffic in China), and then let OUT take CN2 GIA to provide good access quality. There are 163 in the front section and large-capacity networks of overseas operators to provide traffic cleaning, and CN2 GIA to guarantee the service quality when returning home. This is basically an excellent configuration scheme at present, and there is no one. This feature is still that the price of GIA bandwidth is too high, and there will be no cheap products.

What is an IPLC line?

IPLC is an international private rental line. The essence is a peer-to-peer intranet. The entrance of the network is in China, so it will not be affected by international links, and it is not necessary to go through the national firewall. The availability rate of IP address is high. Won't be walled. If you export abroad, you can visit websites that are inaccessible in China at will. Because of the intranet, it is not affected by network fluctuations. Delays abroad are generally low. Therefore, the price is very expensive, but the speed is fast and the delay is particularly low.

Popular science of the most complete network lines: the difference and connection between IPLC special line, CN2, BGP, CIA and ordinary lines

First of all, see Shao. What is IPLC special line?

IPLC is an international private rental line. The essence is a peer-to-peer intranet. The entrance of the network is in China, so it will not be affected by international links, and it is not necessary to go through the national firewall. The availability rate of IP address is high. Won't be walled. If you export abroad, you can visit websites that are inaccessible in China at will. Because of the intranet, it is not affected by network fluctuations. Delays abroad are generally low. Therefore, the price is definitely expensive, but the speed is fast and the delay is particularly low.

Then introduce what is CN2 circuit

CN2 is called the next generation bearer network of China Telecom, English Chinatelecom Next Carrier E115EN, abbreviated as CNCN, and abbreviated as CN2 in the next step, which is divided into cn2 gia and cn2 gt

CN2 GT: CN2 belongs to Global Transit (also known as GIS-Global Internet Service), which has a low grade in CN2, with provincial/overseas nodes starting at 202.97 and international backbone nodes having 2 ~ 4 CN2 nodes starting at 59.43. The congestion degree on the overseas route is 1, which is slightly stronger than that of the 163 backbone network, and the cost performance is also higher than that of CN2 GIA.

CN2 GIA: CN2 belongs to Global Internet Access, with the highest grade. The provincial/overseas/international backbone nodes all start with 59.43, and there is no node starting with 202.97 in the whole process. It performs best on overseas routes, with little congestion, the fastest and most stable speed in theory, and of course, the price is higher than that of CN2 GT.

Generally speaking: CN2 gia is better than CN2 GT. For more knowledge about cn2 circuit popularization, please refer to: cn2 circuit popularization

Secondly, the BGP circuit under 1 is introduced

BGP (Border Gateway Protocol, Border Gateway Protocol) is a routing protocol used to connect independent systems on Internet. It is an enhanced, sophisticated and scalable protocol developed by the Internet Engineering Task Force. The BGP computer room is called BGP computer room, which uses BGP scheme to realize double-line interconnection or multi-line interconnection. The BGP server is commonly referred to as multiwire in our 1

Simply put: There are many ISP bandwidth providers in the computer room, which can intelligently switch the best lines for your users. So the characteristic is global. If your user base is global, using BGP is definitely the wisest choice.

Finally, explain 1. What is CIA line?

The CIA line is the cn2+163 hybrid line.

163 combined with CN2 GIA, which is a rare scheme adopted by ISP, CN2 GIA We mentioned above have a very small backbone network, It's easy to stop eating because of attack, Therefore, we provide 163 IN to ensure that customers' business will not be interrupted by attacks (high traffic attacks are too costly, They all use bandwidth to resist the lack of proximity, so they access the 4134 bandwidth of 100G to solve the traffic in China), and then let OUT take CN2 GIA to provide the best access quality. There are 163 in the front section and large-capacity networks of overseas operators to provide traffic cleaning, and CN2 GIA to guarantee the service quality in China, which is basically the best configuration scheme at present. This characteristic is still that the bandwidth price of GIA is too high, and there will be no cheap products.
