Abstract

This paper presents a mechanism for active resource management (ARM) in a differentiated services environment. While the differentiated services architecture and the bandwidth broker agent provide a mechanism for QoS management through resource reservation, this mechanism is based on a static provisioning of resources. As bandwidth requirement are typically dynamic, such a static reservation approach can either lead to wasted bandwidth or leave applications resource-starved. The active resource management approach presented in this paper addresses this problem by dynamically reallocating resources based on current network state and applications requirements. An implementation and evaluation of ARM using the NS-2 simulation toolkit is also presented.
