Suppose that TCP$\text{'}$s current estimated values for the round trip time $($estimatedRTT$)$ and deviation in the RTT $($DevRTT$)$ are $350$ msec and $25$ msec, respectively. Suppose that the measured RTTs is $320$ msec

What is the value for TCP$\text{'}$s timeout value in msec? Use the values of a $=0\mathrm{.}125,$ B $=0\mathrm{.}25$Consider the figure below, which shows the application$-$to$-$application throughput achieved when two senders are competing at a shared bottleneck link. Suppose that when the overall arrival rate, lambdain' $($for each sender$)$ is close to R$/2,$ the throughput to the application layer $($at each $.$'receiver$),$ lambdaout, is equal to $0\mathrm{.}6*$ lambdain.

What fraction of the packets transmitted at the sender are retransmissions?
