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 continued demands for this
bandwidth, although conventional optical networks struggle in
achieving this, due to the limitation of the electrical bandwidth
barrier. Flexgrid technology is a promising solution for future
high-speed network design. To promote an efficient and scalable
implementation of elastic optical technology in the
telecommunications infrastructure, many challenging issues related
to routing and spectrum allocation (RSA), resource utilization,
fault management and quality of service provisioning must be
addressed. This book reviews the development of elastic optical
networks (EONs), and addresses RSA problems with spectrum fragment
issues, which degrade the quality of service provisioning. The book
starts with a brief introduction to optical fiber transmission
system, and then provides an overview of the wavelength division
multiplexing (WDM), and WDM optical networks. It discusses the
limitations of conventional WDM optical networks, and discusses how
EONs overcome these limitations. It presents the architecture of
the EONs and its operation principle. To complete the discussion of
network architecture, this book focuses on the different node
architectures, and compares their performance in terms of
scalability and flexibility. It reviews and classifies different
RSA approaches, including their pros and cons. It focuses on
different aspects related to RSA. The spectrum fragmentation is a
serious issue in EONs, which needs to be managed. The book explains
the fragmentation problem in EONs, discusses, and analyzes the
major conventional spectrum allocation policies in terms of the
fragmentation effect in a network. The taxonomies of the
fragmentation management approaches are presented along with
different node architectures. State-of-the-art fragmentation
management approaches are looked at. A useful feature of this book
is that it provides mathematical modeling and analyzes theoretical
computational complexity for different problems in elastic optical
networks. Finally, this book addresses the research challenges and
open issues in EONs and provides future directions for future
research.
