MCQ (Single Correct Answer)

The distance between two stations M and N is L kilometers. All frames are K bits long. The propagation delay per kilometer is t seconds. Let R bits/second be the channel capacity. Assuming that processing delay is negligible, the minimum number of bits for the sequence number field in a frame for maximum utilization, when the sliding window protocol is used, is:

$$\left\lceil {{{\log }_2}{{2LtR + 2K} \over K}} \right\rceil $$

$$\left\lceil {{{\log }_2}{{2LtR} \over K}} \right\rceil $$

$$\left\lceil {{{\log }_2}{{2LtR + K} \over K}} \right\rceil $$

$$\left\lceil {{{\log }_2}{{2LtR + 2K} \over {2K}}} \right\rceil $$
