RESUMO
In this work we studied Routing and Wavelength Assignment (RW A) algorithms on Wavelength Division Multiplexing Optical Networks, using discrete event simulation and analytical modeling. Fixed routing, alternate routing and adaptive routing algorithms were implemented. The effect of the number of wavelengths per optical fiber, number of optical fibers and use of wavelength conversion on the performance of the network was considered. The simulation software was written in C++ programming language, using object oriented methodology, in order to achieve efficiency and portability. The analytical modeling used a reduced load approximation with Poisson probability distribution call arrivals and exponential holding times. The analytical results were compared with the results from simulation, for fixed and alternate routing
