What are the advantages of renting dual IP and dual line servers?
What is single IP double line
The common single IP double line refers to the realization of double line technology by setting an IP in the server, that is, Netcom or Telecom IP, setting messages through routing equipment, and sending messages through the telecom network or Netcom network. This solution can also improve the access speed of Netcom users and telecom users, and solve the problem of setting dual IP and dual line routing in the server. However, because the IP address is used by Netcom or telecom IP, the access user will not automatically identify the best route when sending request packets. Therefore, the solution can only be said to be a half two line technical solution, which is a transitional form of the solution. This scheme is usually a temporary scheme for the transition from a single line IDC service provider to a double line IDC service provider.
How to realize BGP line with single IP and double lines
BGP protocol is mainly used for interconnection between Thai Internet as vps (autonomous system). The main function of BGP is to control route propagation and select the best route. Both China Netcom and China Telecom have access numbers, and most of China's major network operators connect to their access numbers through the BGP protocol. To realize two lines with this solution, you need to apply to CNNIC (China Internet Network Information Center) for IDC's own IP address and as number, and then broadcast to network operators such as Netcom and Telecom through the BGP IP address. After all the backbone networks of Netcom and Telecom are interconnected through BGP protocol, the best route of IP routing equipment is determined in the IDC room to ensure the best route for high-speed access of Netcom and Telecom users. Double IP and double line advantages of server rental:
1。 The server only needs to set one IP address. The backbone router in the network determines the best access route according to the technical indicators such as the number of route hops. It will not occupy any system resources of the server. The server can choose the best route for up and down routing to achieve high-speed single IP two-way access.
2。 Because the BGP protocol has the characteristics of redundant backup and loop elimination, when the IDC service provider has multiple BGP interconnects, route backup can be realized. When a line fails, the line will automatically switch to another line.
3。 The use of BGP protocol can also make the network [server and South Korea] highly scalable, connect IDC network with other operators, and easily realize single IP multiple lines. All interconnection operators have very fast user access. This is incomparable with dual IP and dual line.
Guangzhou server? What are the advantages of renting dual IP and dual IP? To sum up, each of the above has its advantages and disadvantages. Both have low intellectual property costs, but the network is unstable and takes up a lot of server resources. The common single IP dual line is part of the dual line, and the access speed is very poor. CDN method has good effect on static web, but it is not ideal for interactive web. First of all, it is the best way to solve the BGP routing problem of a single IP, but there are few IDC service providers using this solution in China at present. If CDN doubles the single IP of BGP, this will be the best solution. There are many data centers sharing BGP technology solutions in China, but most of them provide services for special customers, and few of them are for ordinary users.
