It's just plain vanilla round-robin load balancing. I use other tools to detect services that die, queues not clearing etc. I also use freevrrpd for failover. There use to be a project called lload. This apparently in conjunction with ipfw could do weighted load balancing but I can't seem to find that anymore. I guess it died. I'm sure there might be similar projects though.
