1.Consider sending a large file from a host to another over a TCP connection that has no loss.

1)Suppose TCP uses AIMD for its congestion control without slowstart. Assuming TCP is pipelined with n packets, cwnd increases by 1/n MSS every time a ACK is received, round-trip time is constant and cwnd starts at 3MSS, how many RTTs it takes for cwnd increase from 3 MSS to 6 MSS (assuming no loss events)?

2)What is the average throughout (in terms of MSS and RTT) for this connection up through time = 3 RTT? Assume in the first RTT, cwnd = 3 MSS.
