What is the initial behavior of the congestion window in TCP during the Slow Start phase?
💡 Hint: Consider how quickly TCP ramps up its sending rate.

Challenge Problems
Push your limits with advanced challenges
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.
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.
