Do you observe delayed acknowledgements? Why is the outcome expected?
What will be an ideal response?
We do not observed any delayed ACKs. This is because the link was so slow that when data containing packets arrived, there was always data available to be sent and ACKs could be piggybacked immediately without the need to wait. Almost all acknowledgements are piggybacked in the next segment which send new characters or send echo of the characters. Because of the fast input, the receiver does not need to wait until delay interval reaches. There are always some characters in the buffer to send and the ACKs are piggybacked.
