This study focuses on the routing and Wavelength-Assignment (RWA) problem in
wavelength-routed optical WDM networks. Most of the attention is devoted to such networks …

The problem of routing and wavelength assignment (RWA) is critically important for
increasing the efficiency of wavelength-routed all-optical networks. Given the physical …

For optical networks, routing and resource allocation which considerably determines the
resource efficiency and network capacity is one of the most important works. It has been …

Wavelength converters increase the traffic-carrying capacity of circuit-switched optical
networks by relaxing the wavelength continuity constraints. We consider the problem of …

The advent of fiber optic transmission systems and wavelength division multiplexing (WDM)
have led to a dramatic increase in the usable bandwidth of single fiber systems. This book …

Given a graph whose vertex set is partitioned, the partition coloring problem (PCP) requires
the selection of one vertex from each partite set, such that the subgraph induced by the set of …

In this paper, we consider traffic grooming in WDM/SONET ring networks when the offered
traffic is characterized by a set of traffic matrices. Our objective is to minimize the cost of …

Optical networks and the related technologies, network management software and services
have undergone remarkable developments, and such networks are now the ultra-high …

Wavelength routed optical networks have emerged as a technology that can effectively
utilize the enormous bandwidth of the optical fiber. Wavelength converters play an important …

In this paper, we give an overview of well-known routing and wavelength assignment (RWA)
algorithms, and develop a novel classi cation for some of their main features. The objective …
