Tcp congestion control – consider sending a large file from one host to another over a tcp connection that has no loss. a) suppose tcp uses aimd for its congestion control without slow start. assuming cwnd increases by 1 mss every time a batch of acks is received, and assuming constant round-trip times, how long does it take for cwnd to increase from 1 mss to 6 mss? b) what is the average throughput (in terms of mss and rtt) for this connection up through time = 5rtt?
