Node throughput and packet delay

Title: Node throughput and packet delay

Hi,

 I am new in ns. Several questions:
 1. How to simulate the throughput of the node? For example, I have $n1 and
    $n2, the link between them is with bandwidth 2M bps. But $n1 can only
    process data at 500kps (the $n1 throughput). How to simulate that?

 2. How to trace the packet delay time and variation?

Thanks,
