Question

41. Consider an optical fibre link of length 1000 kilometres with a 1 gigabits/sec data rate connecting a sending and receiving node. Assume a fixed packet length of 1250 bytes. Assume that the sender always has packets to send and packets are never lost or corrupted. Light rays travel at 2x108 m/s in fibre optics cable. What is the utilization of this link for a stop-and-wait (saw) protocol? What is the necessary window size to achieve 100% utilization for a sliding window (sw) protocol?
