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
LOL bad joke.
you're right on the DDos, Smurf and Synflood. Jmeter
is already a pretty good tool for flooding a webserver

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.

Heh :) Peter, watch out, there are cases, where a people were syn flooded just
for calling "(h/cr)ackers" as "script kiddies" :))) (have you read
way cool!
now I just script kiddies don't get the bright idea they can use jmeter for DDOS.

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

My checkpoint fw relies on the source IP when doing loadbalancing. It
remembers client IP for a few minutes and redirects all the traffic f
I guess I'm spoiled :) Usually I have atleast 2 machines to run load tests, or I use
my own development environment of 4 servers. I definitely see value of being able to
test out load balancers like Tomcat5 or hardware load balancer like Cisco
LocalDirectory.

What about IP aliasing - you can define multiple IP's to one network
interface. Then you could ask jMeter to send request from particular IP
(without any modification of TCP header). With that, webservers could do
a reverse lookup. But now there is no possibility in jMeter to choose
the IP requests
unfortunately, the only reliable way to make it appear one JMeter is 10 different IP
addresses is to modify the TCP header.
Even if you change the HTTPHeader, if the webserver uses reverse lookup, it will
figure out it is the same machine. Your best option is to use 10 machines to hit the
