The main function of the BGP protocol is to control the spread of routes and select the best route. China Telecom, China Unicom, China Mobile, and some large third -party IDC service providers released AS numbers by the China Internet Information Center. Some of the high -quality and own networks of major network operators across the country, most of them are BGP protocols used to broadcast IPs with each other to achieve multi -line interconnection between autonomous domains.
Operators and third -party IDC service providers are widely used by the BGP protocol to achieve AS (Autonomous Domain) interconnection is also the primary way to solve the domestic North -South interconnection problem.
However, in recent years, users often see the so -called server BGP dual -line access to such promotional slogans when choosing a server hosting or renting a server. However, in the actual use of users, it is not possible to feel the low latency of the real BGP network and the experience of across the network. So, is this so -called BGP dual -line a real BGP line?
Small and medium -sized data center BGP dual -line is a dual -line IP dual -line connection mode, that is, setting up Unicom or telecommunications IP on the server, and judging the data packet through the telecommunications network or Unicom network sending route device. This solution can increase the cross -network access speed of Unicom users and telecommunications users to a certain extent. Solving single IP Due to the use of Unicom or Telecom, dual -line access needs to set up route IPs. Therefore, when the user sends a request data package, the server sends the server, the server sends the server, the server is sent, and the server is sent to the server. Do not automatically identify the best route. Therefore, this solution is just a transitional compromise solution called a static solution BGP line. In other words, when the static BGP changes when the network structure changes, the operator cannot automatically adjust the network settings as soon as possible to ensure the user experience.
Based on the set search protocol, the dynamic BGP can automatically optimize the network as soon as possible to maintain the stability and efficiency of the network used by customers. Therefore, a dynamic BGP network is called a real BGP.
Why choose? What about the BGP line? The main reason is as follows:
1. The essential difference between BGP lines and ordinary lines
The classic definition of the autonomous system is a set of router IGPs used under the control of the management agency to other autonomous system BGP use the term of the autonomous system to emphasize the fact that the management of the autonomous system provides a unified unified autonomous system for other autonomous systems to provide a unity of other autonomous systems. The internal selection plan provides a consistent description for the network that can be reached. The BGP protocol is an external gateway protocol EGP substitute for communication between different autonomous system routers. The BGP system can reach information between the network. This information includes the linked diagram of the autonomous system AS autonomous system that data to reach these networks is built through this information, and then according to the global BGP routing table to avoid the ring circuit and select the best path.
The real BGP line machine rooms are agreed by the Internet AS because the interconnected BGP protocol between autonomous systems is a dynamic switching route information between autonomous systems, that is, the so -called dynamic BGP.
2. How to distinguish whether to use the BGP line server?
First of all, understand whether IDC has obtained the most basic line requirements for the hard condition BGP such as digital AS.
Secondly, the server can use various webmaster tools IP testing. The test results can be highly referenced.
3. In daily use, when the BGP inter -network visit, the line speed increases significantly. After the user is easy to perceive the BGP protocol interconnection, it will judge all the backbone routing device IDC computer room IP of the network operator to ensure high -speed visits by users of different network operators. The best Internet.
