Hi Members,

Please tell me what would be appropriate  simulation scenarios for
bufferbloat problem ?

The canonical examples are home connections, DSL or cable, with say a
couple of thousand packets of buffer for a 10 Mbps down 2 Mbps up
asymmetrical connection.  That should easily demonstrate what you are
looking for.

please give me some ideas for ftp/cbr traffic with dumb-bell topology.
what should be delay and bandwidth for bottleneck link and for other links?
How many traffic sources should be there?

Why don't you try a few scenarios and see where the bloat starts to
show up, based on a realistic home scenario?  It's pretty easy to
demonstrate in the real world, so you shouldn't have too much trouble
in a simulation.

[Codel] Different scenarios for seeing bufferbloat

[Rich Brown]

Here are two ways you can make bufferbloat happen in real life:

1) Use the Quick Test for Bufferbloat:
http://www.bufferbloat.net/projects/cerowrt/wiki/Quick_Test_for_Bufferbloat

2) Configure your network interface to have a slower data rate and
send a lot of data over it.
