Consider The Figure Below Which Plots The Evolution Of Tcp S Congestion Window At The Beginning Of Each Time Unit Wher 1 (190.7 KiB) Viewed 22 times

Consider the figure below, which plots the evolution of TCP's congestion window at the beginning of each time unit (where the unit of time is equal to the RTT; i.e. a transmission round). TCP Reno is used here. In the abstract model for this problem, TCP sends a "flight" of packets of size cwnd (the congestion window) at the beginning of each time unit. The result of sending that flight of packets is that either (i) all packets are ACKed at the end of the time unit, (ii) there is a timeout for the first a packet, or (iii) there is a triple duplicate ACK for the first packet. 38 cwnd 14 12 10 8 DINO 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 Transmission round In which time interval(s) does TCP operate in Congestion Avoidance? none of the mentioned O (1,6] OTCP always operates in Congestion Avoidance O [1,6] and [13,18] O [6,12), (18,30]
