A simple and straight-forward load balancer for TCP connections, written in Rust. A sample configuration file shows off the current features:

• Any number of backends that will perform round-robin load balancing over a number of target addresses.
• Any number of frontends listening on a port and forwarding all requests to a single backend.

The load balancer is built on top of the mio library, which provides a fast and memory-efficient event driven architecture.

Run it from a cloned copy of this repository. To run the included sample configuration, simply type:

cargo run -- -c sample_config.toml
