Performance implications of meshing degree for WDM-based networks

We study the influence of meshing degree (nodal degree) on the performance of WDM networks with wavelength routing. It is shown that the increase of the nodal degree from 2 to 3 leads to high nodal degree gains, whereas the increase of the nodal degree from 4 to 5 leads to small nodal degree gains. These results make topologies with nodal degrees of 3 and 4 very attractive for WDM mesh networks.
