The effect of physical layer impairments in route and wavelength assignment in Wavelength
Division Multiplexed optical networks has become an important research area. When the …

Abstract In a Wavelength Division Multiplexed (WDM) optical network, data is communicated
using modulated optical signals. In a WDM network, corresponding to each connec-tion …

In WDM all-optical networks without wavelength conversion, traffic rerouting is motivated
either by an optimization of resource utilization or by network survivability. In this paper, we …

With Wavelength Division Multiplexing (WDM) technology, multiple optical signals, using
different carrier wavelengths, can be transmitted simultaneously and independently over a …

In this paper we investigate traffic-engineering issues in Wavelength Division Multiplexing
(WDM) alloptical networks. In such networks, the wavelength continuity constraint along with …

In Wavelength Division Multiplexed (WDM) networks with dynamic lightpath provisioning,
connection requests are served without any prior knowledge of their arrival and departure …

Lightpath rerouting is a viable and cost effective solution to improve the network throughput
conditioned by the wavelength continuity constraint in all-optical networks. Two traffic …

Optical networks play a major role in supporting the traffic in backbone computer networks.
Routing and Wavelength Assignment (RWA) is the technique used to establish a light-path …

In order to set up a number of lightpaths to satisfy user requirements for data communication,
the static (also called offline) Route and Wavelength Assignment (RWA) problem must be …

This paper proposes a new wavelength retuning (WRT) scheme in an all‐optical WDM
network. Compared with the existing WRT schemes developed for all‐optical networks …
