Re: Monitoring

Hi,

I can only answer your second question. The following script installed an
error model ($em) on the simplex-link from $node0 to $node1. You can refer to
Chapter 11 of "ns Notes and Documentation" for more information about error
model.

    set em [new ErrorModel]
    $em unit byte
    $em set rate_ 0.01
    $em drop-target [new Agent/Null]
    [$ns set link_([$node0 id]:[$node1 id])] install-error $em

It seems to me that you MUST specify a drop-target or ns won't drop the error
packets.
