What is a dual-line virtual host? In view of this problem, this article introduces the corresponding analysis and answers in detail, hoping to help more partners who want to solve this problem to find a more simple and feasible way.

Two-line virtual host is also known as intelligent two-line virtual host and intelligent two-line website space, which can solve the problem of interconnection between southern and northern telecom and Netcom users. Intelligent dual-line virtual host means that the same server has two lines of telecom network and Netcom network at the same time. Through routing intelligent judgment of user IP address, telecom users can access telecom lines when visiting websites, and Netcom users can visit Netcom lines when visiting websites, so as to achieve the purpose of mutual visit between the north and the south.

At present, there are two main networks of Telecom Netcom in China, most of which are connected by telecom in the south and Netcom in the north, especially in 7-10 provinces, such as Beijing, Hebei, Shandong, Liaoning, Jilin and so on. As Telecom Netcom competes with each other, telecom users visit Netcom websites, and Netcom users access telecom websites very slowly. Whether you put your website in the telecom room or Netcom room, you will lose the other half of your customers.

The emergence of dual-line virtual host is to solve the problem of slow exchange of visits between telecom and Unicom, and can reduce the cost of maintenance and hardware investment. The specific solution is to access telecom and Unicom lines on a server at the same time to solve the problem of mutual visit between the two lines. Through DNS intelligent parsing technology, its content information visitors or users can use the same region or the same network with fast access to ISP or exchange visits as far as possible to access the services provided by them at a high speed.

1. False double line

Telecom Netcom website mirror, in fact, in Telecom Netcom each has a website, through CDN acceleration to achieve dual-line function, but this leads to:

A, the cost is high: a set of websites needs to buy 2 spaces.

B, high maintenance cost: update a website to update the data of Telecom and Netcom at the same time.

C, there are some programs are not applicable: for some website programs, it will lead to data out of sync, there will be great problems. For example, the pictures uploaded by telecom users on the telecom website can not be seen by Netcom users.

2. True double lines

Full network routing or dual-line access is a link layer technology for network access. It means that the data center computer room where the server is located has a variety of network exits such as Netcom and telecom at the same time, and the whole network routing technology is set up on the upper switch of the computer room. so that the server can be automatically assigned to the fastest link every time it connects to the external network. As a result, both telecom and Netcom users can access at high speed at the same time.

This is the end of the answer to the question about what is a two-line virtual host. I hope the above content can be of some help to you. If you still have a lot of doubts to be solved, you can follow the industry information channel for more related knowledge.
