Abstract :
This paper shows that the main challenge in remotely configurable optical networks lies in how networks should be designed and sized for dynamic traffic in the face of uncertain forecasts, so as to minimize capital expenses, predominantly due to the need to predeploy (or overprovision) resources in preparation for the next connection request. In addition, this paper demonstrates how the operational savings promised by such capabilities measure up against the added capital expenses. Consequently, new ways to provision resources in the network to minimize these expenses are proposed. The results are based on real-world long-haul networks and costs.
