Re: [ns] Problems with bind...

Hi,

Thanks for the reply..I tried it out, but it didnt work. I think

1) For this to work, I must have defined methods by which the param can be
transferred at command line option ..This is what I am trying to do here,
right ? .(please correct me if I am wrong)

2) Moreover, this will create a seperate instance of Queue/ARO. So if I gave
something like

$ns simplex-link $n0 $n1 0.5Mb 10ms ARO
$ns queue-limit $n0 $n1 10000
set aro [new Queue/ARO]
$aro set rho_targ_ 0.8

instead of just this
#Queue/ARO set rho_targ_ .8

then would both be attached to the same instance ?? Shouldnt I attach them
explicitly ?

Thanks
