City Guilds Model Questions Vol1 2023 Information Technology Question 19
Practice objective / multiple choice question 19 from the 2023 City Guilds Model Questions Vol1 Information Technology examination.
A TCP connection starts with a congestion window (cwnd) of 1 MSS and a slow‑start threshold (ssthresh) of 8 MSS. No packet loss occurs. The sender receives acknowledgments for a total of 12 MSS of data. During slow start the cwnd doubles each round‑trip time (RTT); after cwnd reaches ssthresh it enters congestion avoidance, where cwnd increases by 1 MSS per RTT. Determine the value of cwnd (in MSS) after the 12th ACK has been received and indicate in which phase (slow start or congestion avoidance) each RTT occurs.
