Thispaper presents a newpractical approximationalgorithmfor wavelengthassignmentto splitablelightpathsover WDM rings, with the objective ofminimizing the number of SONET ADMs. All...
We consider the problem of minimizing the number of ADMs in optical networks. All previous theoretical studies of this problem dealt with the off-line case, where all the lightpat...

We study grooming for two-period optical networks, a variation of the traffic grooming problem for WDM ring networks introduced by Colbourn, Quattrocchi, and Syrotiuk. In the two-...

We consider the problem of traffic grooming in WDM ring networks. Previous studies have focused on minimizing aggregate representations of the network cost. In this work, we consid...
— In all-optical networks that use WDM technology it is often the case that several communication requests have to be blocked, due to bandwidth and technology limitations. Minimi...
