The assured forwarding (AF) based service in a differentiated services (DiffServ) network fails to provide bandwidth assurance among competing aggregates under certain conditions, for example, where there exists a large disparity in the round-trip times, packet sizes, or target rates of the aggregates, or there exist non-adaptive aggregates. Several mechanisms have been proposed in order to address the problem of providing bandwidth assurance for aggregates, using only the knowledge gathered at ingress routers. In this paper, we present a control theoretic approach to analyze these mechanisms and explore the reasons when they fail to achieve bandwidth assurance under some circumstances. Then we propose a simple but robust controller for this problem, namely, the variable-structure adaptive CIR threshold (VS-ACT) mechanism. We validate the analysis and demonstrate that VS-ACT outperforms several other mechanisms proposed in the literature over a wide range of network dynamics through extensive simulations.
