TCP load balancer written in Python
This is a pure-python TCP load balancer. It takes inbound TCP connections and connects them to one of a number of backend servers.
Features
- async i/o based, so much less overhead than fork/thread based balancers. Can use either twisted or python’s standard asyncore library twisted is recommended, and asyncore support will be removed in a future version.
- Multiple scheduling algorithms random, round robin, leastconns, leastconns+roundrobin
- If a server fails to answer, it’s removed from the pool - the client that failed to connect gets transparently failed over to a new host.
- XML based configuration file see a sample
- separate management thread that periodically re-adds failed hosts if they’ve come back up.
- optional builtin webserver for admin sample of the running screen
- webserver has methods suitable for both interactive and automated systems
