1、 What is a two-wire machine room? The two-wire machine room can be divided into two types: multi line single ip (BGP multi line) and multi line dual ip. On the one hand, the defect of multi line and dual ip is that a route has common faults, and the clients of the route cannot browse the network server; BGP route: if a route is finally broken, such as telecommunication optical fiber, the total traffic of the telecommunication network will automatically switch to another route, such as Unicom, and telecommunication network customers can browse normally; In addition, on the one hand, the management method is complex, and the website domain name must be well analyzed, so the maintenance requirements are high.

Second, the difference between them

1. By definition, a multi wire dual IP is a dual wire machine room. Just analysis. You need to analyze 2 IPs.

2. Some of the host rooms using multi line and dual IP were made by multi line earlier, again using the previous technology, and some of the host rooms with relatively small operation scale or the existing host rooms. It is more economical to choose this method. Therefore, the overall strength of the host room with bgp double line is reliable. At present, Beijing, Shanghai, Guangzhou, Shenzhen and Zhengzhou have bgp multi segment host rooms, which are the backbone connection points of Internet technology. Zhengzhou bgp host room is the most suitable when the speed of website opening across the country is the same.
