Q5 (a) Fig.Q5(a) shows an excerpt of the transmission phase of a TCP connection. Copy Table Q5 to your answer book and complete it for the message exchange. Assume the length of all the TCP headers are 20 bytes. (6 marks) Client Server SYN Payload 250 byles Payload 450 bytes 120 bytes Time Time Fig. Q5(a) Message ACK SYN Total SequenceACK Number 524 338 Number Length 20 4 Table Q5 (b) A process on Host A has been assigned port p, and a process on Host B has been assigned port q. Is it possible for there to be two or more TCP connections between these two ports at the same time? (3 marks) Consider the effect of using slow start on a line with a 10ms round-trip time and no congestion. The receive window is 24KB and the maximum segment size is 2 KB How long does it take before the first full window can be sent? Given that the slow (c) start threshold is set at 32KB (3 marks) Q5 (a) Fig.Q5(a) shows an excerpt of the transmission phase of a TCP connection.
