[c-nsp] Testing big routers

[Jason Ford]

Kim,

We did this in the past using LoadRunner.

Theory is you have a director and load many endpoints (normal PCs) on 
each port of the router. Create a test plan that uses high bandwidth 
between the endpoints like ftp transactions and run it for ~30 minutes. 
If each device is connected via gigabit on both ends, you can route the 
traffic over any technology you have listed below.

This should give you the load you are looking for. There are also other 
hardware devices out there like Smartbits you can use to generate traffic.

We leased these types of things for a month to do our testing so that we 
didn't have to buy them. Take the information for what is it worth!

Good luck!
