Elastic Optical Networks: Fundamentals, Design, Control, and Management

Flexgrid technology is a promising solution for future high-speed network design, but it faces challenges related to routing and spectrum allocation (RSA), resource utilization, fault management, and quality of service provisioning. 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. It also focuses on different node architectures and compares their performance in terms of scalability and flexibility. State-of-the-art fragmentation management approaches are looked at, and mathematical modeling and analyzes theoretical computational complexity for different problems in elastic optical networks are provided.

The rapid advancement in communication and internet technologies has brought about significant transformations in our daily lives and the ever-increasing demand for communication bandwidth. While conventional optical networks have faced challenges in meeting this demand, optical networks have the potential to address these challenges and meet the growing demands. Flexgrid technology emerges as a promising solution for future high-speed network design. However, the successful implementation of elastic optical technology in the telecommunications infrastructure requires the resolution of numerous complex issues related to routing and spectrum allocation (RSA), resource utilization, fault management, and quality of service provisioning.

This book aims to provide a comprehensive review of the development of elastic optical networks (EONs) and address the RSA problems associated with spectrum fragment issues, which degrade the quality of service provisioning. The book begins with a brief introduction to optical fiber transmission systems, followed by an overview of wavelength division multiplexing (WDM) and WDM optical networks. It explores the limitations of conventional WDM optical networks and discusses how EONs overcome these limitations. The book presents the architecture of EONs and delves into its operational principles. To conclude the discussion on network architecture, the book focuses on the different node architectures and compares their performance in terms of scalability and flexibility. It reviews and classifies various RSA approaches, highlighting their advantages and disadvantages.

Furthermore, the book delves into various aspects related to RSA, such as spectrum fragmentation, which is a significant issue in EONs. It explains the fragmentation problem in EONs, discusses, and analyzes the major conventional spectrum allocation policies in terms of their effects on spectrum fragmentation.

In conclusion, this book offers valuable insights into the development of elastic optical networks and addresses the challenges associated with RSA in spectrum fragment issues. It provides a comprehensive understanding of EONs, their architecture, and operational principles, and explores various RSA approaches and their implications. By addressing these issues, the book contributes to the advancement of elastic optical technology and its potential to revolutionize the telecommunications infrastructure.
