Suppose that you are using an extended version of TCP that allows wihdsw SIDU much larger than 64K bytes.' Suppose you are using it over a 1Gbps link with a round-trip time (RTT) of 200ms to transfer 16M-byte file, and the TCP receivers advertised window is 2M bytes. If TCP sends IK-byte segments, and assuming no congestion and no lost segments: (a) How many RTTs does it take until the sender's congestion window reache 2M b ytes? Recall that the congestion window is initialized to the size of a single segment, and assume that the slow-start threshold is initialized to a value higher than the receiver's advertised window (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 times the RTT value, what is the effective throughput for the transfer? What percentage of he link capacity is utilized?
