Two senders (S1 and S2) on the left and two receivers (R1 and R2) on the right. Sender S1 uses TCP Tahoe, and S2 uses TCP Reno. Assume that the MSS (maximum segment size) is 1 KB, that the one-way propagation delay for both connections is 100ms. The link joining the two routers have a data rate capacity (bandwidth) of 8Mbps. Here, cwnd1 and cwnd2 be the values of the senders’ congestion windows.

Question
Two senders (S1 and S2) on the left and two receivers (R1 and R2) on the right. Sender S1 uses TCP Tahoe, and S2 uses TCP Reno. Assume that the MSS (maximum segment size) is 1 KB, that the one-way propagation delay for both connections is 100ms. The link joining the two routers have a data rate capacity (bandwidth) of 8Mbps. Here, cwnd1 and cwnd2 be the values of the senders’ congestion windows.
a. What is the smallest value of cwnd1+ cwnd2 for which the link joining the two routers stays busy all the time?
b. After 8 more RTTs, approximately what are the values of cwnd1 and cwnd2?
