Inapproximability Results for Wavelength Assignment in WDM Optical Networks
We address the issue of inapproximability of the wavelength assignment problem in wavelength division multiplexing (WDM) optical networks. We prove that in an n-node WDM optical ne...

Interdomain RWA Based on Stochastic Estimation Methods and Adaptive Filtering for Optical Networks
Abstract- This paper presents a RWA strategy based on the stochastic estimation of the Effective Number of Available Wavelengths (ENAW) along interdomain paths. We propose an appro...

Dynamic Wavelength Routing in WDM Networks under Multiple Signal Quality Constraints
—Most research works in routing and design of optical networks assume that the optical medium can carry signals without any bit error. However, the physical impairments on the op...

Minimizing Request Blocking in All-Optical Rings
— 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...
