BalanceNG - A modern Software Load Balancer
BalanceNG ("Balance Next Generation") is a modern software IP load balancing solution available for Linux and Solaris operating systems. BalanceNG is small, very fast and quite easy to use and setup. It offers session persistence and many different distribution methods (like Round Robin, Random, IP-Address Hash, Least Resource, Least Session, Least Bandwidth and even a custom distribution method plugin). BalanceNG supports VRRP (Virtual Router Redundancy Protocol) to set up High Available (HA) configurations on multiple BalanceNG nodes. A special mode called "local DSR" (local Direct Server Return) allows production quality HA server load balancing without any additional hardware.
