Hi,
Iam looking for some application (free) that generates continuous traffic on a DS3 link. Wanted to test a new DS3 link with full capacity and move it production, once completed. Any suggestions on the application to use..?
TIA

Hello Mehboob,
you can try to use netperf it requires to be installed on two linux or freebsd boxes one on site A and one on site B
see
http://www.netperf.org/netperf/NetperfPage.html
I've used it some years ago you can use UDP streams or TCP streams
(TCP results can be lower)
Hope to help

I just tested this a few days ago. Iperf will work on both Windows and Unix platform. This is really a good tool.
If you want to saturate the DS-3 link, it is probably best to use UDP instead of TCP:
On the server:
iperf -u -s
On the client:
iperf -u -c 192.168.1.218 -b 45M -t 86400
[Expert@neo-fwlog]# iperf -u -c 192.168.1.218 -b 45M -t 86400
------------------------------------------------------------
Client connecting to 192.168.1.218, UDP port 5001
Sending 1470 byte datagrams
UDP buffer size: 256 KByte (default)
------------------------------------------------------------
[ 3] local 192.168.1.245 port 44737 connected with 192.168.1.218 port 5001
[ ID] Interval Transfer Bandwidth

That will tell you if your DS-3 is fully utilized.
Easy right?

Here is a graphical front end to iPerf written in Java. You may need to rework the shell script to launch it if you are running Vista x64 as it uses 32-bit java and the path is changed to Program Files (x86).

Thanks Nick. I am planning to use XP PC/laptop (one at each end) for the test.
