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 of communications and the internet has brought about significant changes in our daily lives and the demand for communication bandwidth. While conventional optical networks have faced challenges in meeting this demand, optical networks have the potential to enable us to fulfill these requirements. However, conventional optical networks encounter limitations due to the electrical bandwidth barrier.

In order to promote the efficient and scalable implementation of elastic optical technology in the telecommunications infrastructure, several challenging issues related to routing and spectrum allocation (RSA), resource utilization, fault management, and quality of service provisioning must be addressed. This book aims to provide a comprehensive review of the development of elastic optical networks (EONs) and address 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 and then provides an overview of wavelength division multiplexing (WDM) and WDM optical networks. It discusses the limitations of conventional WDM optical networks and highlights how EONs overcome these limitations. The book presents the architecture of EONs and explains its operation principle.

To complete the discussion of network architecture, the 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 advantages and disadvantages. The book also delves into various aspects related to RSA, such as spectrum fragmentation, which is a significant issue in EONs.

Spectrum fragmentation in EONs refers to the division of a continuous spectrum into smaller fragments, which can lead to interference and reduced communication quality. The book explains the fragmentation problem in EONs, discusses, and analyzes the major conventional spectrum allocation policies in terms of their effects on spectrum fragmentation. It also explores alternative spectrum allocation policies that can mitigate the fragmentation problem and improve the overall performance of EONs.

In conclusion, this book provides a comprehensive overview of the development of elastic optical networks and addresses RSA problems associated with spectrum fragment issues. It highlights the limitations of conventional optical networks and explores how EONs overcome these limitations. The book also discusses the different node architectures and compares their performance in terms of scalability and flexibility. Additionally, it reviews and classifies different RSA approaches and explores alternative spectrum allocation policies to mitigate the fragmentation problem and improve the overall performance of EONs. By addressing these challenges, this book contributes to the advancement of elastic optical technology and its potential to transform the telecommunications infrastructure.
