Suppose that TCP increased its window size by two segments rather than one for each ACK received during slow-start. In this scenario the first window would consist of 1 segment, the second window would consist of 3 segments, the third window would consist of 9 segments, etc. For the variables K, P, and Q, used in the analysis of TCP latency:

a) Express K in terms of O and S.

b) Express Q in terms of RTT, S, and R.

c) Express the latency of a TCP connection in terms of P, O, R, and RTT.
