Question

Assume that there are two parallel tcp transmissions in the network, one using tcp tahoe (regular tcp), the other using tcp reno (the one that considers fast recovery). assume the initial ssthresh for both tcp transmissions is set to that a timeout (without dup acks) is detected right after the 8th rtt, and another timeout (with 3 dup acks) is detected right after the 12th rtt.display the results for the first 15 rounds.indicate the size of congestion window in each transmission round (one round corresponds to one rtt). indicate the value of ssthresh in each round.

In the 8th round of TCP transmissions, what is the size of the congestion window for TCP Tahoe?
A) ssthresh
B) 1
C) 2
D) 3

Answer 1

The congestion window size for TCP Tahoe in the 8th round after a timeout is detected is 1 MSS, as TCP Tahoe sets it to this value following a timeout event.

Step-by-step explanation:

The size of the congestion window for TCP Tahoe in the 8th round of TCP transmissions, after a timeout is detected, is 1 MSS (Maximum Segment Size). In TCP Tahoe, when a timeout occurs, the congestion window is set to 1 MSS and the ssthresh is typically set to half of the congestion window size before the timeout, but not less than 2 MSS. Therefore, in the 8th round, TCP Tahoe would have reduced its congestion window to 1 MSS.
