Are you sure? BGP server lease Must the BGP route be used? If not, how do we know that BGP servers are leased through BGP lines? Is there any way? Don't worry, the following article will follow Tengyou Bianxiao to understand.
The main function of BGP protocol is to control route propagation and select the best route. China Telecom, China Unicom, China Mobile and some large third-party IDC service providers all have AS numbers issued by China Internet Information Center. Most of the high-quality private networks of major domestic network operators use BGP protocol and broadcast IP to achieve multi line interconnection between autonomous regions.
1. Is the BGP line used for leasing BGP servers?
First, select Server lease , our enterprise should know whether the server renter has obtained the AS number and other hard conditions, which is the most basic requirement of BGP line. Secondly, you can use various network management tools to test the partition of the server IP segment, and the test results are highly referential. Third, in daily use, the speed of BGP line cross network access is significantly improved, which is easy for users to perceive. After the BGP protocol is used for interconnection, all the backbone routing equipment of the network operator will judge the best interconnection route to the IP segment of the IDC machine room, so as to ensure high-speed access of users from different network operators.
When selecting a BGP machine room, users should pay attention to whether the service provider meets the "hard conditions" for operating the BGP machine room, that is, there is an as number issued by CNNIC or APNIC, and the IP segment applied to it and broadcast through the BGP protocol. If the above conditions are not met, the network services of BGP server renters often cannot meet the requirements of low latency and high redundancy. Even so, users should also BGP server lease The merchant's line shall be tested in detail to understand the real situation of its line quality.
2. The essential difference between BGP line and ordinary line
The classic definition of an autonomous system is a group of routers under the control of a management organization, which uses IGP and general indicators to forward messages to other autonomous systems. The term "autonomous system" is used in BGP to emphasize the fact that the management of autonomous system provides a unified internal routing plan for other autonomous systems, which provides a consistent description of the network that can be reached through it. BGP protocol is an external gateway protocol for communication between routers in different autonomous systems, and it is a substitute for EGP protocol. The reachable information of the network is exchanged between BGP systems. This information includes all the paths in the autonomous system AS that data must pass through to reach these networks. This information is used to construct the link graph of the autonomous system, and then avoid the loop and select the optimal path according to the global BGP routing table.
The real BGP line room is interconnected between AS (autonomous systems) through the Internet, because the BGP protocol is a protocol for dynamic exchange of routing information between autonomous systems, also known as dynamic BGP.
See the above Yes BGP server lease , Micronet wants to remind enterprise users that most domestic BGP server renters are called BGP double line or multi line, which does not meet the above conditions. Therefore, users with demand for BGP lines need to have a clear understanding of the current market situation, which further demonstrates that real BGP double line/multi line BGP server renters are limited in China. So you must think carefully when choosing.
