A source in Vancouver has established a TCP connection to a destination in Tokyo over a transatlantic T3 optical fiber line (~45 Mbps) with an RTT of 50 msec. The destination has indicated a window size equal to the maximum allowed by the window size field in TCP. a) Ignoring TCP's slow start phenomenon and assuming no packet loss, what is the percentage of time that the source spends waiting for the destination's acknowledgement? Assume zero processing delay at the destination. b) What is the effective bitrate of this connection? c) What is the efficiency of this connection? d) What would be the efficiency of this connection if it was over 56Kbps modem (old Internet), as opposed to T3? RTT is still 50 msec. e) To alleviate the efficiency problem, RFC 7323 suggests extending TCP's window size field by an additional 14 bits, borrowed from TCP's options field. What would be the efficiency of the T3 connection under RFC 7323?
