When renting overseas servers, many users do not understand the differences between the CN2 line and the BGP line. I do n’t know if the CN2 line or BGP line is selected, or for the overseas server, is the CN2 line or the BGP line?

　　The CN2 line is a new generation of high -quality overseas commercial networks in China Telecom. Unlike the traditional 163 backbone network, CN2 returns directly to high -speed high -speed, and it is much faster in single speed (low latency and low packet loss rate). CN2 is divided into two types: CN2 GIA and CN2 GT. Overseas lines usually refer to CN2 GIA. When renting overseas servers, the CN2 GIA line is useful.

　　BGP line, in fact, BGP is not a network line, but the BGP routing protocol. Its computer rooms access multiple lines (including domestic and foreign network operators). Using the BGP routing protocol can better dispatch the network. BGP is divided into optimized direct link width (that is, the optimized 163 network) and international bandwidth. Contains the CN2 line, which is second only to the CN2 line.

　　Which line of overseas server CN2 and BGP is better?

　　If you look at performance alone, overseas servers must be the better CN2 line to choose the overseas dedicated line, but CN2 also has disadvantages. CN2 bandwidth resources are small (you can refer to the line of overseas large bandwidth server, no CN2). It is impossible to bear network attacks. The bandwidth resources of the BGP line are sufficient and large exports. It is the choice of dealing with large bandwidth consumption and defense attacks. For domestic users, especially optimizing the direct connection line, the advantage is more than CN2, which can be said to be five or five. The speed of direct connection is relatively slow, but there are many ways to increase overseas server speed, such as the acceleration of commonly used CDN nodes.
