Flow control is a technique used for ensuring the sending entity and preventing the buffer overflow with a propagation delay of 30 msec and bit rate of 5 kbps. However the source may break up a large block of data in to smaller blocks and transmit the data in many frames. Find out the frame size range calculation for stop and wait protocol for the given efficiency of 25 and 50%. Write your reflection for the result obtained from different efficiencies for stop and wait protocol.
