Extracted text: Additive-Increase, Multiplicative Decrease (AIMD) refers to... a. TCP increases its round-trip time estimate by 1 second with each ACK received, and divides it by two with each loss event. O b. TCP's congestion control mechanism in the congestion-avoidance phase, in which the congestion window is increased by 1 maximum segment size (MSS) every round-trip time (RT), and decreased by 1/2 when there's a loss event indicated by 3 duplicate ACKS. c. TCP's ability to add additional receivers, one-by-one, until there are too many receivers. At this point, TCP reduces the number of receivers by 1/2 by sending those receivers a reset (RST) packet.
