re $3\mathrm{.}54-$ TCP congestion avoidance sending rates: TCP Reno and

TCP CUBIC

$($a$)$ Suppose that at t$3,$ the sending rate at which congestion loss next occurs increases to $1\mathrm{.}5*$Wmax$.$ Show the evolution of both TCP Reno and TCP CUBIC for at two more rounds each.

$($b$)$ Suppose that at t$3,$ the sending rate at which congestion loss next occurs drops to $0\mathrm{.}75$&Wmax. Show the evolution of both TCP Reno and TCP CUBIC for two more rounds each.
