Are there any tools available for configuration of load-balancing, either as a part of OpenBSD or as a port/package?

What exactly is it that you want to load balance?

Any particular services in mind?

[kremlyn]

I didn't really have any particular services in mind. The question came about when there was talk about round-robin DNS in #openbsd on irc.openprojects.net (which is where I am 90% of the time).

I was thinking there might be an open-source utility that could, based on a number of decisions (such as load, throughput, etc. calculations), forward traffic for a given port to a particular internal machine.

I havn't been able to find anything.. and it seems to be a project that the Open Source community could use..

"Balance is a simple but powerful generic tcp proxy with round robin load balancing and failover mechanisms. Its behaviour can be controlled at runtime using a simple command line syntax."

"Load Balancer Project is an attempt of write a tool that allows to balance request using clusters of servers."


both found via a http://freshmeat.net search for "load balance". you may find other interesting projects there.
