Today, what the editor shares with you is the advantages of the BGP multi-line computer room and the single-line computer room, which many people do not quite understand. Today, in order to let you know more about the BGP computer room, the editor summed up the following contents. Let's look down together. I'm sure you'll get something.

BGP (Border Gateway Protocol) is mainly used for the interconnection between Internet AS (autonomous systems). The main function of BGP is to control the propagation of routes and choose the best route. China Netcom, China Telecom, China TieTong and some large private IDC operators all have AS numbers. Most of the major network operators in China achieve multi-line interconnection through the BGP protocol and their own AS numbers. To use this scheme to achieve multi-line interconnection, IDC needs to apply for its own IP address segment and AS number in CNNIC (China Internet Information Center) or APNIC (Asia-Pacific Network Information Center) (currently Netcom is a member of both APNIC and CNNIC), and then broadcast this IP address to the networks of other network operators through the BGP protocol. After interconnecting with BGP protocol, all backbone routing devices of network operators will judge the best route of IP section of IDC computer room to ensure high-speed access of users of different network operators.

Advantages of BGP multi-line computer room:

1. The server only needs to set an IP address, and the best access route is determined by the backbone router on the network according to route hops and other technical indicators, and will not occupy any system resources of the server. Both uplink and downlink routing of the server can choose the optimal path, so it can really achieve high-speed single-IP high-speed access.

2. Because BGP protocol itself has the characteristics of redundant backup and elimination of loops, when IDC service providers have multiple BGP interconnection lines, they can backup each other's routes, and when one line fails, the route will automatically switch to other lines.

3. Using BGP protocol can also make the network have strong expansibility, can interconnect IDC network with other operators, easily realize single IP multi-line, and make the user access of all interconnected operators very fast. This is incomparable with double IP and double lines.

Advantages and disadvantages of using BGP multi-line computer room and single-line computer room

BGP multi-line computer room:

1. The computer room supports multiple lines, so that Internet users at terminals such as China Telecom, China Unicom and China Mobile can access quickly, and there is no cross-line jump. If there is a problem with the mobile optical cable in one of the lines, the mobile user can be automatically switched to another line. Mobile users will not be able to access the server.

2. Some large IDC companies are self-built, with significant service advantages, such as 7x24 server failure maintenance, relatively flexible, such as increasing bandwidth, ip resources, and using backup server / backup hardware to replace users' down servers or faulty hardware in time. The most important thing is that they do not have to go through the bureaucratic formalities and procrastinate for a long time, and the speed is very fast. It's actually doing something for the client.

3. The downside is that BGP lines are expensive. The same machines and bandwidth are much higher than those of single lines. The larger the bandwidth, the greater the proportion. Generally, companies that use gigabit bandwidth or above basically do not use BGP multilines. In addition, the bandwidth of the exit of the BGP multi-line computer room is not as sufficient as the single line, and the attack can withstand, and the network with large traffic such as 20g will lose packets.

Single-line computer room:

The biggest advantage of single-line computer room is large bandwidth and low cost, and sufficient bandwidth at the exit of the computer room. On the other hand, the advantage of BGP is the disadvantage of single-line computer room, and the most unbearable is the problem of machine failure and maintenance at night and holidays, which is very slow. Of course, in single-line computer room, there are generally big customers such as 360,360,360,360,360,100. One or two machine failures do not affect the distribution of clusters, and the servers all have remote control cards.

If your user group is relatively concentrated, the traffic is very large, such as basically users in the north or a certain city, you can consider putting it in a single-line computer room, cheap and money-saving. If the business is to serve national users or local telecom Unicom accounts for half of the market, the traffic is less than 100 megabytes on the BGP multi-line, the speed is fast, and the server is guaranteed.
