My personal experience with the base SIPp (rather than IMS bench) is that you
will be very lucky to make this work. If you are thinking of multiple
instances, then it is fairly easy to measure the data space per instance (or
per call) and multiply it by the number of instances and see if you have enough
real memory to do that. In either case, each IP address and each UDP port has
an overhead in the OS and they will mount up. We found that Linux just slowed
to a crawl with more than 20K IP addresses and UDP ports in use. There is also
a C library limit (10K from memory) that limits the number of streams per
process (you can recompile the library but we never went there).
We did solve the problem, but outside of SIPp.

Subject: [Sipp-users] SIPp IMS Bench : Query on Virtual IP Config on Test System
To: sipp-users@lists.sourceforge.net
Hi All ,
I want to configure multiple IP address on my Test System which will generate
traffic for near about 200,000 users for my SUT where i have installed
OpenIMSCore. Now as i see the pre-requisites in the IMS Bench SIPp installation
procedure there its written " The actual number of IP addresses to configure
will depend on the transport option you select: a single IP address per SIPp
instance, in which case you need many IP addresses as you'll run SIPp instances
on a same physical system, or multiple IP addresses per SIPp instance in which
case you will want plenty of IP addresses."
Now in my Test System i want to have 2 SIPp instances , each of whom will be
generating 100,000 users traffic.
So , now my question is which transport option will be suitable for me?
Shall i go for 1 IP address per SIPp instance , or i keep only one single SIPp
instance having 100,000 IP addresses?
Secondly , connecting both the Pc's , my TEST SYSTEM and my Desktop running
OPenIMSCore ( SUT) , i am using CAT 5 cable connector. Will that be suitable
for conencting? I have installed 2 separate network adapters for this case in
both the PC's.
Any suggestion on this scenario will be very helpful ,
Regards ,
Sougata
