Zero-budget network dimensioning

Traffic engineering has been widely used to improve network performance while keeping the resource utilization balanced. The existing traffic engineering approaches, however, lead to network upgrades from time to time. While these upgrades might be successfully financed during economic prosperities, it poses a problem when the economic situation deteriorates. We propose in this paper a novel approach that is able to reveal whether a traffic re-engineering is necessary. In case budget is not available for upgrades, this approach can optimally decide which demand to satisfy so as to maximize network operators' revenue. We demonstrate the usefulness and the effectiveness of the approach by conducting traffic engineering on an example network and by describing some of its added values as well.
