Assume that we have a TCP connection between A and B. A has the following initial values: Congestion Window: cwnd=504 bytes (if MSS=504 bytes) Slow-start threshold: ssthresh=2520 bytes Advertised window stays the same at 5000 bytes throughout this data exchange (meaning on every ACK a window size of 5000 bytes is indicated) Given the following events occur at A: Time t=0: A sends 1 segment to B Time t=1: A receives an ACK for 1 segment Time t=2: A sends 1 segment to B Time t=3: A receives an ACK for 1 segment Time t=4: A sends 2 segments to B Time t=5: A receives an ACK for both segments Time t=6: A sends 2 segments to B Time t=7: A receives an ACK for both segments Time t=8: A sends 2 segments to B Time t=9: A receives an ACK for one segment Time t=10: A receives an ACK for the second segment Time t=11: A sends 1 segment to B Nothing happens between t=12-19 Time t=20: A has a time out and retransmits the segment that was sent out at time t=11 Time t=21: A receives an ACK for 1 segment Time t=22: A sends 1 segment to B At each time slot, what is the size of cwnd and ssthresh?
