What is BGP double line? What's good about BGP double line? When it comes to these professional issues, many people don't understand them very much, and they don't understand too much. It is the so-called professional things to be done by professional people. So today, Micronet will take you to understand what is BGP I hope it can be helpful to you for the good of double line and BGP double line.

First, let's understand the implementation principle of the single IP dual line BGP protocol, as follows:

This scheme maps one IP directly to another IP through BGP protocol. When a user accesses an IP, the best route is automatically selected, which will not bring slow delays through different ISPs to the user What is BGP? The border gateway protocol is mainly used to realize the interconnection between Internet ASs. The main function of BGP is to control the propagation of routes and select the best route. Both China Netcom and China Telecom have AS numbers, and most of the major network operators in China are interconnected with their respective AS numbers through the BGP protocol. Adopting this scheme to realize double lines requires that you first apply for the IDC's own IP address segment and AS number at CNNIC (China Internet Information Center), and then broadcast the IP address to other network operators, such as Netcom and Telecom, through the BGP protocol. After the BGP protocol is used for interconnection, all the backbone routing equipment of Netcom and Telecom will determine the best route of the IDC machine room's IP segment, So as to ensure the high-speed access of Netcom and telecom users.

What's good about double line BGP? Micronet believes that there are several reasons:

I The server Only one IP address needs to be set. The backbone router on the network determines the best access route according to the number of route hops and other technical indicators. It will not occupy any system resources of the server. The optimal path can be selected for both the upper and lower routes of the server, so that high-speed access of single IP and double line can be realized.

2、 Because the BGP protocol itself has the characteristics of redundant backup and cancellation loop, when the IDC service provider has multiple BGP interconnection lines, it can realize mutual backup routing. When one line fails, it will automatically switch to other lines.

3、 The use of BGP protocol can also make the network have a strong scalability, enable the IDC network to interconnect with other operators, facilitate the realization of single IP multiple lines, and enable users of all interconnected operators to access faster. This is not comparable to dual IP dual line.

Micronet believes that although BGP is the best solution, it requires IDC suppliers' investment in equipment and bandwidth, and is technically complex. Therefore, the current domestic adoption of this solution is limited to professional IDC service providers with strong strength.

The above is what Micronet introduced to you about BGP double line and what is good about BGP double line. I hope it will be helpful to you.
