Jitter Emulation Tools

Hi everybody.

I'm trying to create a test environment that is capable of generating jitter.

Has any of you been able to emulate this with Cisco routers (I managed to create packet loss and delay but never jitter)?

I read about Linux/Free BSD tools that can be used for this (dummynet and NIST-NET).

Any ideas?

Thanks

Re: Jitter Emulation Tools

Jitter can be measured by deploying Cisco routers 17xx or higher with Cisco IOS software code version 12.05T or higher, and configuring the Cisco IOS SAA features. The routers should be placed in the campus networks next to hosts. This provides statistics for end-to-end connections. Since it is not practical to measure every possible voice path in the network, place the probes in typical host locations providing for a statistical sampling of typical voice paths. Some examples include:

a local campus-to-campus path

a local campus-to-remote campus path via a 384 kbs Frame Relay circuit

a local campus-to-remote campus via an ATM permanent virtual circuit (PVC)
