Distributed Dynamic Resource Allocation in Quality of Service Networks

Efficient network provisioning mechanisms are essential to support service differentiation in the Internet. In this paper we propose a distributed provisioning architecture for intra-domain Quality of Service networks. We propose a new service model and we characterize the demand behavior of network’s users based on physically reasonable utility functions. This allows us to develop an efficient bandwidth allocation algorithm that aims at maximizing the users’ benefit and the ISP revenue. As a key innovative feature, the proposed bandwidth allocation algorithm takes explicitly into account traffic statistics. We demonstrate through simulation in realistic network scenarios that the proposed dynamic provisioning model is superior to static provisioning in providing resource allocation.
