$1\mathrm{.}4\mathrm{.}13\mathrm{.}5$ Maximum Throughput $(1).$ Consider again the network shown above, where R$2=$ R$3=25$ Mbps again. What is the maximum end$-$to$-$end throughput achieved by each session, assuming the sender is sending to receivers at the maximum rate possible?

Question $22$ options:

Each session achieves a maximum throughput of $25$ Mbps$.$

Each session achieves a maximum throughput of $50$ Mbps$.$

Each session achieves a maximum throughput of $100$ Mbps$.$

The TCP session that starts first achieves a maximum throughput of $100$ Mbps; the other session is starved and gets $0$ Mbps$.$

Each session achieves a maximum throughput of $10$ Mbps$.$
