RE: Assigning different IPs for different Virtual Users from the
same Machine
Two issues we've seen with IP based load balancing are:
Super proxy farms (like AOL's) will bounce users around to different IP
addressed proxy servers so to decrease bounces in your server farm you'll
need to expand the IP sticky range from a single IP to something like a
class C address block.
Increasing the sticky scope to a class C block will likely result in one
server in your farm receiving more than it's share of load.

fun discussion. I think most hardware load balancers use the IP address,
which is also one of the compliants many people have about them. Atleast if
you ask Resonate, which makes software load balancing. I believe Cisco
routers can also use session based load balancing, which gets around the
performance issues of lots of traffic coming from a specific IP address.

Posted by peter lin <jm...@yahoo.com>.
the other approach that I've seen first hand is
session based load balancing. I've used resonate in
the past with session based load balancing. setting it
up can be a bit tricky, but it does work.
in the case of resonate, the have a heart beat on all
the servers in the cluster. the load balancing
algorithm is hash of several different performance
measurements like network IO, cpu, memory and so on.
Other systems I've worked with used a similar approach
to generate hashes for load balancing.
