BalanceNG

BalanceNG is a modern, IPv6 capable software IP load balancing solution. It is small, fast, and easy to use and set up. It offers session persistence, different distribution methods (Round Robin, Random, Weighted Random, Least Session, Least Bandwidth, Hash, Agent, and Randomized Agent) and a customizable UDP health check agent in source code. It supports VRRP to set up high availability configurations on multiple nodes. It supports SNMP, integrating the BALANCENG-MIB with Net-SNMPD. It implements a very fast in-memory IP-to-location database, allowing powerful location-based server load-balancing.

Release Notes: A new multithreading scheduler has been implemented (activated by "set multithreading 1"). The new directive "interface N threads" controls the number of threads per interface (if the multithreading scheduler is active). A new informational command "show threads" shows thread information (if multithreading is activated). A minor bug has been fixed, server "-1" is no longer reported when there's no 1:1 server/target relationship. A new module "crossover" allows the implementation of a virtual crossover cable (Linux only). The manual has been updated accordingly.
