Linux virtual server competition

[Stefan Sonnenberg-Carstens]

Hi list, I'm sure anyone here knows about the linux virtual server (layer 4 load-balancer). I searched the web for an equivalent for *bsd, but found none. The only thing which looks like something like a load-balancer is the FreeBSD loadd, which requires packets to copied from kernel-space to user-space and vice versa. I know that OpenBSD/pf has some abilities for load-balancing ip packets. I'd like to know if it goes beyond the round-robin stuff (e.g. schedulars for least-connection,weighted round-robin), or if just does that. I've played arround with load-balancers (F5 BigIP,local director) and would like to write one for *BSD's, if there is a demand for that (and to get my hand dirty on code again). Would it be a good idea to integrate it into a packet-filter (like the lvs) or implement it as a stand-alone solution ?   Any comment is welcome. Hope this is not to off-topic.   Regards, Stefan Sonnenberg-Carstens
