Abstract

We present a new approach to WDM multifiber network design and optimization under static traffic aimed to minimize the number of fibers in the network. The heuristic optimization comprises an initial setup of all the demanded lightpaths and an iteration during which the network is progressively improved by rerouting lightpaths and consequently eliminating fibers with a high number of unused wavelengths. In our approach static traffic is actually managed with the same techniques as dynamic traffic by suitably sorting the static connection demands and offering them in sequence to the network. The employment of the multifiber layered graph as a template to represent the network states allows to compare a very wide range of routing, fiber and wavelength assignment criteria, link metrics, wavelength-conversion environments and so on. In this paper we will show and discuss the optimization of a particular case-study network and we will analyze the influence of various design parameters on the final results.
