Abstract
This paper considers planning and optimization of WDM networks by means of Integer Linear Programming (ILP), which is the most used exact method to perform this task. Since survivability is a very crucial issue in order to guarantee QoS in optical WDM networks, new ILP formulations are investigated here to design WDM networks under protection strategy with shared transmission resources. These formulations are applied to multifiber mesh networks with or without wavelength conversion. After presenting the formulations we discuss the results we obtained by exploiting them in the optimization of a case-study network.
