Consider a TCP flow over a 1-Gb/s link with a latency of 1 second that transfers a 10 MB file. The receiver advertises a window size of 1 MB, and the sender has no limitation on its congestion window (i.e., it can go beyond 64 KB). (a) How many RTTs does it take until slow-start opens the send window to 1 MB? (b) How many RTTS does it take to send the file: (c) If the time to send the file is given by the number of required RTTS multiplied by the link latency, what is the effective throughput of the transfer? (d) What percentage of the link bandwidth is utilized?
