Title: Planning Models for Network Robustness: Survivability and Flexibility

Abstract: Since many of today's networks, e.g., for telecommunications or power distribution, are called upon to reliably deliver high levels of traffic over it links, they should be carefully designed to have sufficient capability and capacity - not only to satisfy expected demands for service, but to be able to respond to unexpected conditions as well. Traditional models had dealt separately with planning for the potential for network damage - like a cut in a link or an equipment breakdown - and designing a network that would be capable (on the average) of satisfying demands whose models are appropriately stochastic in nature. In this talk we describe some approaches to combining these models because it turns out that the same planning strategies provide for both forms of network robustness.
