TCP load balancer in Haskell

Ye

A simple TCP load balancer in Haskell

Usage

To install, run

$ cabal install

This will build and copy the binary to $HOME/.cabal/bin/ye (or to the cabal installdir if that is configured)

to run this use:

ye  --listenPort 4242 --remoteHosts mybackend-1.com:4000,mybackend-2.com:3000,mybackend-3.com:80 --debug --balancingStrategy ROUND_ROBIN

or

ye -l 4242 -r mybackend-1.com:4000,mybackend-2.com:3000,mybackend-3.com:80   -d -t ROUND_ROBIN

This starts a listener at localhost:4242 which forwards traffic to the backends:

• mybackend-1.com:4000
• mybackend-2.com:3000
• mybackend-3.com:80

in a round robin distribution

Available balancing strategies

• ROUND_ROBIN
• SOURCE_IP_HASH
