RE: Server Redundancy

[Don Mills <drm2 () dss state va us>]

We've been using the Linux Virtual Server project (which a previous poster 
mentioned) to do load balancing (locally) on web based apps, pop3, smtp and 
now iptable firewalls.  It scales well, has multiple lb algorithms (wlc, rr, 
lc, wrr, etc.) and even multicasts out the connection info if you want so you 
can set up a bank of redundant lb's.  It can work w/ NAT or ip tunneling or 
direct routing so it might be able to do global load balancing depending on 
the setup.  We have a 10000+ user mail farm behind one and haven't seen a 
single hiccup...
