We define data link layer communication efficiency as the ratio between a packet transmission time and the sum of the the packet transmission time and twice of its propagation time. A channel has a bit rate of 10 kbps and a propagation delay of 10,000 micro-second. For what range of frame sizes (in number of bit) does stop-and-wait give an efficiency of at most 90%?
