TCP has been the dominant congestion control protocol in the Internet. Although it is well known that TCP combined with intermediate systems with active queue management (AQM) schemes can not guarantee asymptotical stability when the feedback delay or the link capacity is large, the asymptotical stability may not be necessary for network achieving good performance in terms of resource utilization,...
AIMD/RED (additive increase and multiplicative decrease/random early detection) systems with multiple- bottleneck links are becoming more and more common in the vast-scale Internet. In this paper, we develop a mathematical model of AIMD/RED systems with multiple bottlenecks and feedback delays, which can be brought into the frame of singularly perturbed systems. Stability properties of multiple- bottleneck...
The Additive Increase and Multiplicative Decrease (AIMD) congestion control algorithm of TCP protocol deployed in the end systems and the Random Early Detection (RED) queue management scheme deployed in the intermediate systems contribute to Internet stability and integrity. Previous research based on the fluid-flow model analysis indicated that an AIMD/RED system may not be asymptotically stable...
