Distributed algorithms for fair bandwidth allocation to elastic services in broadband networks

摘要

The Nash arbitration scheme from cooperative game theory provides a natural framework to address the allocation of available bandwidth in network links which is network (Pareto) optimal and satisfies precise notions of fairness. In this paper we propose two distributed bandwidth allocation schemes that allocate available bandwidths to elastic sources according to the Nash arbitration scheme. We prove convergence to the desired allocations for both algorithms. Finally we show how such a scheme can be implemented in a real network.
