When renting a Hong Kong server, most webmasters have speed requirements for it. And the line selection of the computer room will affect the speed of the server in Hong Kong. Then, there are many lines in the computer room in Hong Kong, so which line is the fastest?

Network lines can be divided into single-line, double-line, three-line, bgp lines, and cn2 lines; domestic network operators include China Telecom, China Unicom, and China Mobile. Let's take a brief look at these types of line machine rooms and their differences:

Single-line computer room: refers to only one network operator connected, and only one network line.

Two-line computer room: refers to the access to two of the network operators, with two network lines.

Three-line computer room: refers to the access to three domestic network operators, with three network lines.

BGP line: Also known as a multi-line computer room, it refers to the lines connected to all countries. When the access returns, it will automatically switch to the fastest line, with automatic identification function.

CN2 line: refers to the telecommunications line. CN2 telecommunications line is a high-quality network line (because China Telecom has deployed overseas lines), mainly for global network lines returning home, and has a significant effect on the speed of domestic access to overseas network lines. Among them, CN2 GIA Belongs to the highest level, also known as the return line.

Line difference in the computer room

The server in the single-line computer room does not have any advantages at present. Why do you say that? First of all, the domestic network area is divided into north and south. The southern telecom line is faster, and the northern China Unicom is faster. However, due to the competition between operators, different network lines cannot be exchanged well. For example, a very common example, some game servers are divided into telecom area, Netcom area, etc. What problems will happen when players in the telecom area play in the Netcom area? There is no advantage.

Two-line and three-line computer rooms are more suitable in China, and the access speed is relatively good, which can meet the normal access of domestic users.

The advantage of the BGP multi-line computer room is that it will automatically adjust to the fastest line according to the access request, which is not only applicable to domestic but also international.

The difference between the CN2 line and the BGP line is that the BGP line is the fastest line to return according to the request. It is applicable to any country and belongs to multi-line integration, that is, the BGP line can include the CN2 line or not; and the CN2 line belongs to the return line. , which is a single line, most overseas servers currently rely on the CN2 line. There is no difference in the domestic access speed between the BGP line and the CN2 line, and the speed and delay are similar.

Line selection in the computer room: BGP (including CN2)>CN2>three-wire>two-wire>single-wire

Summary: The speed of the network lines in the computer room in Hong Kong can be known from the above ranking. At present, if you want to ensure the speed from the Hong Kong computer room to China, try to choose the BGP+CN2 computer room line.
