[ns] Queue size problem.

[Hassan Mansouri <hmansour@usc.edu>]

Dear ns users,

I am trying to get the instantaneous size of a queue, I tried this:

set q [[$ns link $n1 $n2] queue]
set qsize [$q set size_]

but I got the error message: can't read "size": no such variable.

Can someone help me find the instantaneous queue size.

Thanks alot.

Hassan.
