That was our concern. Cisco already had hardware to do as good or better
than what ArrowPoint was doing. They would suck in the intellectual

If you go out and spend a few thousand you can also get Allied Telesyn
L2-L4 products that now support Load Balancing. Actually the rapier

Take a look at Nortel's Alteon product line, Cisco's CSS p
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 w

Using outboard appliances for "server load balancing" is unnecessary,
and it adds more powered boxes (thus decreasing theoretical reliability).
If your upstream router can speak OSPF and is made by either Cisco or
Juniper then it will implement ECMP (equal cost multipath). If you put
