To quickly ramp up the connection speed at the start
What is the significance of 'triple duplicate ack' in congestion control?
It prevents data flow interruption due to single packet loss

Resulting speed of the connection
Which technique is used to quickly ramp up data transfer at the start of a connection?
'Slow start'
What purpose does 'Triple duplicate ack' serve in congestion control?
Improve data flow after a single packet loss
In congestion control, 'Vegas' measures delay to detect what?
Congestion window size
What is the primary goal of the 'Cubic' alternative approach in congestion control?

Stop sending packets
What does TCP Vegas do upon receiving a triple duplicate acknowledgment?
Reduce window size by 30%
How does TCP Vegas calculate the window size in response to a triple duplicate acknowledgment?
$0.4 \cdot (t - K)^3 + Wmax$
What does TCP Cubic do in response to triple duplicate acknowledgments?
Reduce window size by 30%
If the window size in TCP Vegas is less than the standard TCP at a given time, what action does TCP Vegas take?
Switch to standard TCP mode
