will rate 2) Recall that in TCP’s AIMD congestion control scheme, when segment loss is detected a TCP connection reduces the value of the threshold parameter to be one-half of the current congestion window. What if we tried a different adaptation such as reducing the value of the threshold by a constant amount instead (i.e., we no longer did a multiplicative decrease)? a) In terms of fair sharing of link bandwidth, would this new TCP guarantee that TCP connections transmitting...
