Assume, for a single connection we need to have an average TCP throughput = 3 Gbps. Assume, RTT= 20 msec and no errors? Question 17 Not yet answered Marked out of 2.00 P Flag question First, the average TCP throughput in GBps is Note( we changed the wints from bit per second to bye per second) How many bytes are traveling per RTT? (The unit is bytes) Now, assume that all segments have a size of 1200 bytes, what will be the window size?

Match the following event at receiver with the corresponding TCP receiver action Question 16 Not yet answered Marked out of 2.00 P Flag question Arrival of in- order segment with expected seq #. All data up to expected seg # already ACked Choose... Choose... immediately send duplicate ACK, indicating seq. # of next expected byte Choose... immediately send single cumulative ACK, ACKing both in-order segments immediate send ACK, provided that segment starts at lower end of gap Delayed ACK. Wait up to 500ms for next segment. If no next segment, send ACK Arrival of segment that partially or completely fills gap Arrival of in- order segment with expected seq #. One other segment has ACK pending Arrival of out- of-order segment higher- than-expect seq. #. Gap detected Choose... Choose...
