Not long ago, it was reported that the mobile phone number could be transferred to the Internet. Under this policy, our mobile phone users can choose a package that is more suitable for them without wasting their mobile phone numbers for many years. For the choice of network, the server hosting users also have the same problem. For the server hosting enterprises, the data transmission speed should be kept at a high and stable level to meet the needs of users. In many cases, the computer room hosted by server users is usually a single line computer room. When other network users access the server, there will be data delay. In order to effectively solve this problem, many users have tried their best.

The most direct way is to introduce bandwidth resources from other networks, but for users in a single line data center, it is unrealistic to use multiple lines on their original servers. Because network access in data does not provide other network resources, in this case, the only possibility for users is to host a server in another data center and connect data with the same network through some technologies.

For this solution, the biggest problem for users is that they need to replicate a server with the same data and internal deployment. In addition, data synchronization between two servers is also a big technical problem. Therefore, the cost of users will become very high.

So now most users will not choose a single line data center. The scheme of multi wire data center is also different. The most common is that the data center connects users to different service providers, and then the network card of the server exchanges data on the server of the street users. Compared with the first technology, this scheme is less difficult. However, according to the network conditions, users need to install more than two network cards in the server.

With the intensification of competition among Internet operators, the types of networks used by users are no longer limited to Telecom and China Unicom. If the problem is solved simply by adding network cards, the hardware redundancy of the server is difficult to meet the actual needs of the end user. In addition, when the network fails, users who use this method to troubleshoot are very laborious. Because the user doesn't know which line is faulty.

From the above point of view, the data transmission from the server host user to the network is technically complex and very expensive. If data exchange is solved in the protocol layer of the data center, can the maintenance cost of users be reduced? In fact, this technology has emerged and been used in many T4 data centers, namely BGP multi wire data centers.

BGP multi line data center can access various network resources, and complete the interactive selection of the best data line in the BGP protocol layer. Because BGP technology has strong fault tolerance, user operation and maintenance become easier.
