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

Abstract

In this paper, 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 degreethree 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 worst than the lower bound of the traffic performance in networks with .~ irregular degree-three topologies.

“…We analysed all topologies of that general regular degree three family and we showed that there are several regular degree three topologies with the same smallest diameter of the chordal ring with smallest diameter and with exactly the same path blocking performance, but we have not found any degree three topology outperforming chordal rings with smallest diameter. In [9], we have obtained a lower bound of the traffic performance in networks with irregular degree three topologies and we have 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 worst than the lower bound of the traffic performance in networks with irregular degree three topologies.…”
