Generally, UDP packets are used by applications that have their own flow
control.

Question: in a switched ethernet environment, assuming the receiving
host is slow in receiving packets (say sender at 1GBPS, receiver is a
VMS host at 10mbps)., will the switch simply drop packets as they
overflow buffers or does twisted pair have a means for the switch to
tell the sender "stop sending, my buffers are full" ?
