Answer

AIMD uses the measured RTT delay to detect congestion.

Answer

AIMD cuts the congestion window size, cwnd, i  to 1 whenever a timeout occurs.

Answer

AIMD always cuts the congestion window size, cwnd, in half whenever loss is detected.

Answer

AIMD uses observed packet loss to detect congestion.

Answer

AIMD cuts the congestion window size, cwnd, in half whenever loss is detected by a triple duplicate ACK.

Answer

AIMD is a end-end approach to congestion control.

Answer

AIMD is a network-assisted approach to congestion control.
