[ns] Variable latency and loss rate

[J S]

Hello
I would like to induce variable latency and loss rate in my simulation.
or transient/persistent congestion.
I plan to use GT-ITM to generate topology, but it only gives static
latencies.

Can I bind some failure rate with some links /nodes
Does any one have any idea (or prototype) to use variable latency and loss
rate in the network?
Or any other pointer which I can follow



Thanks a lot for the help
