Flexgrid technology is now considered to be a promising solution for future high-speed
network design. In this context, we need a tutorial that covers the key aspects of elastic …

The rapid growth in communications and internet has changed our way of life, and our
requirement for communication bandwidth. Optical networks can enable us to meet the …

In elastic optical networks, bandwidth fragmentation refers to the existence of non-aligned
and non-contiguous available subcarrier slots in the set of all subcarrier slots. Since …

For the past several years, traffic especially, Internet traffic has been increased tremendously
and this growth demands for a high-speed communication network such as optical network …

Dispersion in optical fiber degrades the quality of signal in optical networks. Although the
use of dispersion compensating fiber (DCF) reduces the effects of dispersion, it is expensive …

This book presents an in-depth treatment of routing and wavelength assignment for optical
networks, and focuses specifically on quality-of-service and fault resiliency issues. It reports …

In this paper, we design an optimization problem for grooming of multicast traffic requests in
WDM mesh networks. The objective is to minimize the network cost by minimizing the …

Dispersion in fiber optic is wavelength dependent and it degrades the quality of service
(QoS) in an optical network. Although use of dispersion compensating fiber reduces the …

This book is intended as a graduate/post graduate level textbook for courses on high-speed
optical networks as well as computer networks. The ten chapters cover basic principles of …

This chapter introduces the limitations of convention wavelength division multiplexing
(WDM)-based optical networks, and then presents elastic optical networks for future high …
