On the value of wavelength-add/drop in WDM rings with uniform traffic

Summary form only given. For WDM SONET ring networks transporting uniform traffic, we have devised a traffic-bundling methodology that enables one to both quantify the maximum terminal-equipment savings attainable using wavelength-add/drop, and to produce constructions that achieve these optima. Maximum terminal-equipment savings are seen to increase swiftly, over the region of interest, with both network size and inter-node demand.
