RESUMO

This dissertation is a study about the initial traffic deployment in wavelength-routed WDM (Wavelength Division Multiplexing) optical networks with path protection. We make an introduction of the key technologies and the major network planning aspects. We introduce some architectures for transport provisioning to various client network architectures. The RWA (Routing and Wavelength Assignment) problem is introduced, and node-link and link-path MILP (Mixed Integer Linear Program) formulations are compared. The link-path formulation is expanded to incorporate dedicated and spare capacity in the RWA, in more two MILPs. An algorithm for generation of alternative routes convenient to the problem was elaborated. Different traffic restoration schemes are compared: 1+1, pre-configured 1:1, and pre-planned 1:1 and 1:N. The protection/restoration framework is applied to a 15 nodes network. All the algorithms were implemented on the AMPL/CPLEX modelling language.
