Interactive Quizzes
Engage in quick quizzes to reinforce what you've learned and check your comprehension.
Question 1
What is the initial behavior of the congestion window in TCP during the Slow Start phase?
- It increases linearly
- It remains static
- It increases exponentially
💡 Hint: Consider how quickly TCP ramps up its sending rate.
Question 2
True or False: The slow start threshold (ssthresh) moves upward during periods of congestion.
- True
- False
💡 Hint: Think about how TCP responds to congestion indicators.

Challenge Problems
Push your limits with challenges.
Question 1
Calculate the congestion window size after receiving 4 ACKs if the initial cwnd starts at 1 MSS.
💡 Hint: Remember that cwnd doubles with each ACK received.
Question 2
Compare the effects of a retransmission timeout vs. receiving three duplicate ACKs in terms of cwnd adjustment.
💡 Hint: Consider how each event indicates different levels of network congestion.
