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...

A Queueing Network Model of an Edge Optical Burst Switching Node
— We consider an edge optical burst switching (OBS) node with or without converters, and with no buffering. The OBS node serves a number of users, each connected to the switch ov...

Prize-Collecting Steiner Networks via Iterative Rounding
In this paper we design an iterative rounding approach for the classic prize-collecting Steiner forest problem and more generally the prize-collecting survivable Steiner network de...

Efficient dynamic traffic grooming in service-differentiated WDM mesh networks
In this paper, we address the issue of traffic grooming in arbitrary WDM mesh networks. We present a novel groomer architecture wherein a combination of grooming at two different ...

Wavelength Assignment for Satisfying Maximal Number of Requests in All-Optical Networks
In this paper, we study how to, given a set of pre-routed requests in an all-optical network and a set of wavelengths available on each link, assign a subset of requests with maxim...
