Performance assessment of wavelength routing optical networks with irregular degree-three topologies

We present an assessment of the traffic performance in wavelength routing optical networks with regular degree-three topologies of minimum diameter, irregular degree-three topologies, and random topologies with average nodal degrees of three. We have obtained a lower bound of the traffic performance in networks with irregular degree-three topologies. It is shown that this lower bound is very close to the performance of a network with a random topology and an average nodal degree of three, while the performance of a network with a chordal ring topology (regular topology) with smallest diameter is worse than the lower bound of the traffic performance in networks with irregular degree-three topologies.
