Question: ________ treats the two signs of congestion detections, timeout and three duplicate ACKs, in the same way.

Answer:

Tahoe TCP is an early version of the TCP protocol that was developed in the 1980s. It was one of the first TCP implementations to include congestion control mechanisms, which are now a critical part of TCP and are used to ensure that the network is not overloaded with traffic.
Tahoe TCP's congestion control algorithm uses a combination of slow start and congestion avoidance. When a connection is first established, Tahoe TCP uses slow start to gradually increase the amount of data that it sends, in order to probe the network and determine its capacity. Once the congestion window reaches a certain threshold, Tahoe TCP switches to congestion avoidance mode and increases the window size more slowly, in order to maintain a stable flow of traffic and avoid congestion.
In Tahoe TCP, if a timeout occurs or three duplicate ACKs are received, the sender assumes that a packet has been lost and immediately reduces the congestion window size to the initial value, then restarts the congestion control algorithm with slow start. This aggressive response to congestion events can cause the network to become overloaded, leading to high packet loss and delays.
Later versions of TCP, such as Reno and New Reno TCP, improved on Tahoe TCP by introducing more advanced congestion control mechanisms, including fast retransmit and fast recovery. These mechanisms allow TCP to respond more quickly and effectively to congestion events, leading to improved network performance and reliability.
