[NTLUG:Discuss] Load/Network Balancing NICs?

[Scott Womer]

Hiya Peoples!

I'm building up what will become a mission-critical web site at my company.
I'm setting up a fault tolerant infrastructure, dual ISPs, dual routers,
dual firewalls, dual switches and clustered web servers.  I know I can use
simple round-robin DNS to mathmatically balance the load across ISP networks
and web servers, but what I'd like to be able to do is take advantage of the
available fault tolerance of the ISP networks, meaning... if one ISP goes
down, or even a router or firewall, etc... etc... and be able to
automatically redistribute the load to the available connection.

I know there's hardware out there to accomplish this, but I'd prefer to
provide a linux solution.

Any ideas?  Known solutions?


Thanks,
Scott Womer
