[ns] SFQ and DRR queue limit

["Michele R." <mic.rus@libero.it>]

 

Hello!

 

I have:

 

$ns duplex-link $n2 $n3 100KB 2ms SFQ

 

$ns queue-limit $n2 $n3  4 (or another small number like 3 or 5 or 2!)

 

Why it doesn't work?

 

It doesn't work with DRR too.

 

I can't give a queue limit for SFQ and DRR?

 

Thank you.
