The distance between two stations M and N is L km. All frames are K bits long. The propagation delay per kilometer is t s. Let R b/s 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 |
