Check for the MSS given if it is not mentioned take 1 as default otherwise take the mentioned one.

Like refer this problem :- https://gateoverflow.in/1794/Gate-cse-2014-set-1-question-27 it is mentioned MSS = 2KB so we start from that size only.

AIMD is Additive Increase Multiplicative decrease it is the algorithm that is widely popular for congestion control it is same what we have learnt that window size will increase linearly if congestion is not detected and it will reduce to half if congestion is detected.

I don’t think GATE has ever asked about MIMD
