Problem 6:20 Points A 1024-bit message is sent that contains 992 data bits and 32 CRC bits. CRC is computed using the IEEE 802 standardized, 32-degree CRC polynomial. For each of the following, explain whether the errors during message transmission will be detected by the receiver: (a) There was a single-bit error. (b) There were 2 isolated bit errors. (c) There were 5 isolated bit errors. (d) There were 28 isolated bit errors. (e) There was a 28-bit long burst error (f) There was a 39-bit long burst error. Problem 7:10 Points The distance from earth to a distant planet is approximately 8.5 x 1012 m. What is the channel utilization if a stop-and-wait protocol is used for frame transmission on a 400 Mbps point-to-point link? Assume that the frame size is 256 KB and the speed of light is 3 x 108 m/s. Problem 8:10 Points In the previous problem, suppose a sliding window protocol is used instead. For what send window size will the link utilization be 100%? You may ignore the protocol processing times at the sender and the receiver
