Thanks for the response. I knew that TCP handles dropped packets. But it seems like using an exceptional case for dealing with errors shouldn't be the norm. Is this also how more traditional traffic shaping works?

I presume that under circumstances such as this you end up generating a lot more network traffic than you need to, because of the overhead in retransmitting failed packets.

I know you couldn't buffer indefinitely because your buffer would overflow, but could you maybe delay the acknowledgements of packets, e.g. To simulate a slower link.

Not saying there's anything wrong with the approach or article, merely curious from the perspective of a non-networks guy.
