Abstract
This paper presents a performance assessment of wavelength routing optical networks with nodal degrees of 2 and 3. It is shown that the traffic performance of a network, with a random topology and an average nodal degree of 2, is better than ring (degree 2) and some chordal ring (degree 3) networks. It is also shown that the performance of a network, with a random topology and an average nodal degree of 3, is better than chordal ring networks with minimum diameter. This fact leads to the question of the existence of other degree three topologies that outperform chordal rings. We have investigated two new topology families with nodal degrees of 3 and an assessment of their performance is presented.
