In this paper, we present an assessment of the traffic performance in wavelength routing optical networks with regular degree three topologies of small diameter. It is shown that the performance of this kind of networks with diameters slightly higher than the minimum is very close to the performance of networks with minimum diameter. Our results show that there are several regular degree three topologies, with a performance very close to the optimum, that may be implemented in a wide-area environment. These results clearly increase the implementation flexibility of degree three topologies in those environments.
