First of all, let's first understand what CN2 is. CN2 is a China Telecom network line. The full name is China Telecom Next Carrier Network. The English name is Chinatelecom Next Carrier Network, which is abbreviated as CNCN. Since it is composed of two CN letters, it is referred to as CN2. Since it is China Telecom's next-generation network, it means that CN2 has more advanced technology, higher priority, less network congestion, and faster connection speed than the current telecom backbone network (163).
In order to solve the network congestion problem of overseas servers returning to China, China Telecom's CN2 network plays a very critical role here. At present, CN2 is mainly exported from Beijing to London, Shanghai to San Jose, Los Angeles, Frankfurt, Tokyo and Hong Kong, and Guangzhou to San Jose, Los Angeles, Singapore and Hong Kong.
The CN2 network is also divided into high and low levels. The two levels are CN2 GT and CN2 GIA. We will introduce them below: CN2 GT line: CN2 GT is one of the CN2 lines. GT in the name is the head of the English Global Transit. Letter abbreviation, which means global transmission.
CN2 GT is not the highest level among all CN2 lines. Generally speaking, in the domestic and foreign line connection, if the domestic line does not take CN2, but only the line after leaving the country, it is CN2 GT line. When we rent a server, if it is a CN2 server, it is usually a CN2 GT line server, because the CN2 GT line is cost-effective, and most of the CN2 servers on the market are also CN2 GT lines, or the server manufacturer has not emphasized that it is CN2 GIA. Then this kind of server basically belongs to the CN2 GT line.
CN2 GIA line: CN2 GIA is the highest level of CN2 line. The letter GIA is the abbreviation of English Global Internet Access, which means global Internet access.
The obvious feature of the CN2 GIA line is that in the connection route with the target server, CN2 is used from the inter-provincial part of the country, without congestion with ordinary users, so the line optimization is more thorough, it belongs to the dedicated line, and there is less congestion. The connection is faster with minimal interference.
CN2 GIA is currently the highest level of international lines at home and abroad, and is the preferred choice for enterprise and high-end users. Compared with other lines, CN2 GIA has unique connection advantages.
Due to the outstanding characteristics of CN2 GIA, when renting a server, if the server uses the CN2 GIA line, the server manufacturer will put special emphasis on the product instead of simply saying that it is only the CN2 line.
The above is the cn line server explained by Taihai Xiaomei, so do you understand what CN2 server? The server's network transmission node passes through China Telecom's next-generation bearer network, which is the CN2 server.
