Virtual Gate Test Series: Computer Networks - IP Datagram
$DF=1$ so fragmentation will not be done. but what will happen next? datagram just rejected? what will be the strategy of the network to do not loss data and retransmit?

Optimal Window Size
In optimal window size for sender or for finding the maximum window size of sender N, do we consider N=1+2a or N=a. Where a=(propagation time/Transmission time)? For max efficiency: n*Tt should be equal to Tt+2Tp. ie n=1+2a. But in some places it is just n=2a.
