What does a two-wire server mean
Double line server double line access technology (referred to as double line technology) is a special technical means used in an Internet Data Center (IDC). Different ISP services are connected to a server or server cluster, so that users accessing the network services they provide can access each other as quickly as possible through the same ISP or ISP connection, thus solving or alleviating the slow delay (network bottleneck) of cross ISP users accessing websites.
What is a true two-wire server?
First, the false double line, the mirror image of the Telecom Netcom website, actually has a website in Telecom Netcom, but this leads to:
A: Expensive. One website needs to purchase 2 spaces.
B: Maintenance costs are high. Updating a website requires updating the data of Telecom and Netcom at the same time.
C: Some programs in are not applicable. For some website programs, the data will not be synchronized, which will cause great problems.
Some procedures are not applicable. For some website programs, the data will be out of sync and there will be great problems. For example, Netcom users cannot see the pictures uploaded by telecom users to telecom websites.

Ordinary double line: two connections of" Telecom Station "and" Netcom Station "are built on the website page, but customers seldom pay attention to such choices when visiting the website, or customers simply have no patience to visit your website, which will cause your customers to lose. 3、 Intelligent double line: whole network routing or double line access is a link layer technology for network access. It means that the data center machine room where the server is located has multiple network outlets, such as Netcom and Telecom, and the whole network routing technology is set on the upper layer switch of the machine room, so that the server can be automatically allocated to the fast link each time it connects to the external network. Thus, both telecom and Netcom users can access at high speed at the same time. At present, most of the computer room lines in China are divided into: single unicom lines, single telecom lines, dual IP dual line lines, single IP dual line lines, BGP single IP multi line lines, CDN dual line lines. Customers can decide the lines according to their business needs.
Advantages of dual line server over single line server What is it? At present, most of the southern China is connected to the Internet by telecommunications, while most of the northern China is connected to the Internet by Netcom, especially in 7-10 provinces such as Beijing, Hebei, Shandong, Liaoning and Jilin. Because Telecom Netcom competes with each other, telecom users visit Netcom websites, and Netcom users visit telecom websites slowly. Whether your website is located in the telecommunications room or Netcom room, the other half of the customers will be lost. As a result, a dual line or multi line server has been created, which can achieve fast access from north to south and meet the needs of customers for nationwide access. Hardware investment comparison: the hardware investment of two servers is large. I believe that everyone knows that two servers will be more expensive than one server, right? The hosting cost of dual servers is high. Everyone knows that the hosting cost of dual servers and dual servers will be higher than that of one server and dual servers! Comparison of update and maintenance: dual servers are troublesome to maintain and update. If you update this machine, you need to update that one. If you just update Netcom, you need to update Telecom. It is difficult to synchronize data on both sides at one time. And the use of dual path technology can update the data on both sides of the server at any time, so that you can save manpower and valuable time to do more things beneficial to your development.
Difference between two-wire server and single wire server The single line server must be the single line machine room, and the single line machine room is generally divided into telecommunications, China Unicom or mobile lines. For telecom users, the access speed must be fast, but for China Unicom or mobile users, the access speed will be affected to some extent, and users with high requirements for access speed may experience high latency. Therefore, if the customer's business coverage is limited, the customer can consider choosing a single line machine room. After all, the cost will be lower. Because after all, if there are multiple lines, it is technically more complex than the single line implementation. According to the pattern of China North Netcom South Telecom, the majority of users in the south use telecom rooms, while most customers in the north will choose Unicom rooms. With the development of interconnection technology, many enterprise users are now using multi line servers. Almost all telecommunications, China Unicom and mobile lines are covered. Some computer rooms even include education networks, science and technology networks, international export lines, etc., to meet the special needs of some special customers. In short, the choice of dual line server and single line server is not only different in technical implementation, but also has a lot to do with customers' business choices.
