1, the three major operators can be redundant with each other, and can automatically choose the best path to avoid a single point of failure.

2. Low delay, high efficiency and better stability.

3. It is functional.

In dynamic BGP multi-line network, information is exchanged between interconnected switches, and then the routing table entries are optimized according to a certain algorithm. These routing information is constantly updated at a certain time interval to adapt to the changing network and obtain the best routing effect at any time. In order to achieve efficient routing of IP packets, IETF has formulated a variety of routing protocols.

In other words, when the network structure in static BGP changes, operators cannot automatically adjust the network settings at the first time to ensure the user experience. Dynamic BGP can automatically optimize the network structure in the first time according to the set routing protocol, and keep the network used by customers stable and efficient.

Extended data

The difference between dynamic BGP and ordinary static BGP;

1, different composition conditions

Necessary conditions of dynamic BGP bandwidth in Beijing;

The five necessary conditions for self-made dynamic BGP bandwidth are AS number+IP address segment+routing equipment+dynamic BGP bandwidth+transportation management team. Moreover, only the North, Shanghai and Guangzhou have dynamic BGP, which is also called domestic penetration BGP dynamic and dynamic full penetration BGP, but other cities do not.

Static BGP bandwidth composition conditions:

Relatively simple, you can directly find a number of operators to buy bandwidth: as number: none, general operators broadcast on their behalf, and there is no BGP function. Static BGP is also called non-penetrating BGP, and its application condition is also north-south direction. Shanghai, Guangzhou, etc. can be satisfied, using multi-line single IP; Some second-and third-tier cities do not have BGP bandwidth, and only multi-line and multi-IP can satisfy users.

2. It has different functions:

Static BGP has simple functions.

Static BGP bandwidth function can realize multi-network access, but only a few fixed paths lead to several major operators. When a routing node in the direction of an operator fails, it will lead to abnormal communication in the direction of an operator.

Caused a single point of failure, affecting the direction of an operator's exit, resulting in some users unable to communicate normally. The responsibility of repairing faults requires manual intervention, which cannot be repaired automatically, and the processing time is generally long.
