Abstract
In this paper we use fluid-models to look at the adaptation of congestion-controllers to achieve higher throughputs and utilizations in high bandwidth connections. We first parameterize the congestion-controllers using a parameter called the multiplicative decrease parameter and study the adaptation of the congestion-controllers in terms of adapting this parameter. We then linearize the system to study the local stability properties and provide design rules for choosing the parameters of the congestion-controllers. We assume a general network topology and arbitrary round-trip delays in the analysis. Simulations that show the throughput increase that can be achieved using such adaptive congestion-controllers are also presented.
