Server room IP: BGP multi-line server proxy configuration and optimization scheme

How to play BGP multi-line server room agent without lag?

BGP multi-line proxy is like raising an octopus, you have to make each tentacle flexible work. The core of the sentence:Automatic selection of optimal routes with intelligent routing protocolsThe BGP agent will be able to connect you to dozens of carriers directly. Ordinary room agent at most two or three lines, BGP multi-line directly to you dozens of carriers, like ipipgo such professional service providers can be telecom, Unicom, mobile lines kneaded together, automatically matching the fastest channel.

Three strokes to fix the BGP proxy configuration

Don't be intimidated by the technical terms, the configuration process is simpler than you think:

1. Get an interface account with a provider like ipipgo that supports the BGP protocol.
2. Open an opening on the server firewall to expose the proxy port (e.g. 3128 or 8888)
3. Configure routing policy files to assign IP segments from different carriers to corresponding lines

Focus on the routing policy thing, and get a table to make it clearer:

Five Optimization Tips to Make Agents Fly

Configuration is just the beginning, these tawdry operations are the key:

① Dynamic IP pool should be large enough: ipipgo's dynamic IP pool has 90 million + residential IPs, it is recommended to change 3-5 IPs per request to rotate, don't catch an IP.

② Don't be lazy about heartbeat detection: Detect line quality every 5 minutes, encounter jittery lines directly cut the backup channel, the response speed can be improved by more than 40%.

③ The agreement is well disguised.: Disguise proxy traffic as normal HTTPS requests by adding an ssl masquerading layer to the nginx configuration.

Real-world pit-stepping Q&A

Q: What should I do if I always get stuck for 3-5 seconds when switching lines?
A: 80% of the route convergence is too slow, the BGP holdtime parameter from the default 90 seconds to 30 seconds, ipipgo background can directly adjust this parameter.

Q: Will I be recognized if I use multiple carrier IPs at the same time?
A: It depends on how the routing strategy is matched, it is recommended to use ipipgo's intelligent routing function, which will automatically attribute the same carrier traffic to the same outlet to avoid IP hopping.

Q: There are always a few lines that drop out during sudden heavy traffic?
A: In the load balancer set up a traffic fusion mechanism, a single line more than 70% bandwidth will automatically limit the flow, ipipgo's traffic monitoring panel can directly set the threshold.

Why choose a professional service provider?

Tossing BGP proxies by yourself is like doing big data with an abacus, either it doesn't work or it's a lot of work. Take ipipgo for example, they have more than 240 access points around the world, and come with intelligent routing engine. The most crucial thing is that it supportsProtocol masquerading + traffic obfuscationThe technique of disguising proxy requests as normal traffic would take three layers of skin to develop from scratch on its own.

There are eight words at the heart of this agent thing:More lines, faster switchingBGP Multiline was originally created to solve this, find a reliable service provider than their own dead beat efficiency is much higher. The next time you encounter network lag, remember to check the routing table is not the time to update the IP pool is not the time to expand the capacity of these small details piled up is the smoothness of the qualitative change.
