Q$2.$ About TCP$.$ Consider that only a single TCP $($Reno$-$like$)$ connection uses an $8$ mbps link from the source node A to the

destination node B$.$ Assume node A has a very large file to be sent to node B where the receive buffer is sufficiently larger

than any size boundary discussed here. Each TCP segment size $($MSS$)$ is $1500$ bytes. The two$-$way propagation delay $($RTT$)$

of this connection is $150$ ms $($milliseconds$).$ There is no other communication traffic competing with this TCP connection.

Q$2\mathrm{.}2)$ Assume a slow start with no packet loss and the initial threshold is larger than X $($defined in

Q$2\mathrm{.}1),$ how many RTTs $($represented by variable Y$)$ would this TCP connection take to reach its

maximum window size X$?$
