Imagine that we develop a congestion control mechanism based on Multiplicative Increase and Multiplicative Decrease, namely, if congestion occurs, all senders will cut back sending rate by half or otherwise double the sending rate every RTT. Which of the following properties is/are true for this mechanism? Check all that apply. Fair -- it allows equal sharing of bottleneck bandwidth between two TCP connections with the same RTTs. Efficient -- TCP connections will achieve high utilization of bottleneck bandwidth. Convergent -- In absence of further changes in the network, the throughput of existing TCP connections will achieve equilibrium values and have minor fluctuations around them. None above
