Network Performance Modeling, Design and Dimensioning Technologies

An important objective of our work is todemonstrate the utility of these models for effective design anddimensioning of a large network so that a certain set of QoS requirementsare met. We show how typical design and dimensioning problems can beformulated as a multi-objective constrained optimization problem, usingperformance estimation network models; an approach that leads naturallyto very useful trade-off analysis. We describe our research in thedevelopment of a general network design and dimensioning methodology bylinking our performance models with Automatic Differentiation andmulti-objective optimization algorithms and tools. We presentexamples and applications that demonstrate the speed and versatility ofour methodology and algorithms.
