This paper develops an analytical framework to study the optimality of rate-based generic AIMD and AIAD congestion control schemes. In this way, a congestion model is introduced to describe the ... We propose Westwood++ TCP as an implementation of the AIAD paradigm, and we consider Reno TCP as an example of the AIMD mechanism for comparison. We derive a mathematical model of the throughput of the AIAD mechanism that shows that Westwood++ is stable, is friendly to Reno and increases the fairness in bandwidth utilization.
above, AIMD is no longer superior. TCP SACK, active queue management techniques and fair queueing in routers enable the other linear alternatives to provide comparable and sometimes signi cantly better goodput performance. We observe that AIAD is always among the best linear alternatives, and can even

the TCP connections are operating in Congestion Avoidance mode (AIMD) at all times. Figure 3.55 plots the throughput realized by the two TCP connections. If TCP is to share the link bandwidth equally between the two connections, then the realized throughput

There are two connections through the same bottleneck link of capacity R to the same server, as depicted in the figure in slide #2.
A semi-Markov chain (SMC) is proposed to model the steady-state sending rate distribution of source nodes based on the congestion model. The optimality of generic AIMD and AIAD, based on the proposed models, is analyzed in order to maximize the defined rate-congestion ratio (RCR). (AIAD) are two variations of the simple rate adjustments. On the other hand, in the exact rate adjustment algorithm, the rate is adjusted based on the exact congestion level of the network. In this paper, we investigate the performance and the optimality of the generic AIMD and AIAD rate adjustments as the congestion control schemes which are Transmission Control Protocol (TCP) uses a network congestion-avoidance algorithm that includes various aspects of an additive increase/multiplicative decrease (AIMD) scheme, with other schemes such as slow-start to achieve congestion avoidance. The TCP congestion-avoidance algorithm is the primary basis for congestion control in the Internet.

Refer to Figure 3.56, which illustrates the convergence of TCP’s AIMD algorithm. Suppose that instead of a multiplicative decrease, TCP decreased the window size by a constant amount. Would the resulting AIAD algorithm converge to an equal share algorithm? Mar 27, 2013 · P41) Refer to Figure 3.56, which illustrates the convergence of TCP’s AIMD algorithm. Suppose that instead of a multiplicative decrease, TCP decreased the window size by a constant amount. Would the resulting AIAD algorithm converge to an equal share algorithm? Justify your answer using a diagram similar to Figure 3.56.
