In the past few years, there has been growing interest in wide area\All Optical Networks" with
wavelength division multiplexing (WDM), using wavelength routing. Due to the huge …

This paper considers grooming of low speed traffic into high speed lightpaths in a WDM
based optical ring with a primary goal of reducing the cost of the entire system, which is …

This paper attempts to study the impact of wavelength converters in WDM wavelength routed
all-optical networks. A new heuristic approach for placement of wavelength converters to …

A wavelength division multiplexed (WDM) network is considered for arbitrary topologies. The
network allows optical signals to pass through nodes, which often results in less electronic …

SONET add-drop multiplexers (ADMs) are the dominant cost in SONET/WDM rings. They
can potentially be reduced by optical bypass via wavelength add-drop multiplexers …

This paper considers a network design problem introduced which resource allocation is
performed within a Wavelength Division Multiplexing optical ring network to reduce overall …

The traffic-adaptive concept has become the key technology in WDM (optical wavelength
division multiplexing) networks. A genetic algorithm (GA) is proposed for the wavelength …

In this paper we consider the circuit assignment algorithm for dynamic traffic in unidirectional
WDM/SONET ring networks. Our objective is to minimize the cost of electronic add/drop …

Wavelength utilization in WDM wavelength routing networks can be improved by time
division multiplexing sessions on each wavelength, and switching time slots and …

Abstract All-optical Wavelength Division Multiplexing (WDM) backbones are believed to be a
fundamental component in future high speed networks. Currently, the most pursued …
