Lightpath Topology Configuration for Wavelength-routed IP/MPLS Networks in a Multi-layered Environment

Category : Computer network architectures
Languages : en
Pages : 276
Book Description
In this dissertation, we explore the problem of optimal lightpath topology configuration and efficient traffic engineering of IP traffic in wavelength-routed optical networks using a multi-layered environment. First, we consider the shortest path routing framework such as OSPF/IS-IS for IP networks; in particular, we consider non-bifurcated minimum-hop routing to route IP traffic on the lightpath topology. We present a novel model and solve the problem of lightpath topology design and traffic engineering such that all demand pairs have unique-shortest path in the lightpath topology; our approach specifically addresses design in the presence of limited number of transreceivers. To incorporate the survivability requirement such that the lightpath topology remains connected in the event of any single physical link failure, we have extended the above model. In particular, we present a novel solution approach, which designs a unique shortest path-based lightpath topology with the maximum number of links that are part of at least one cycle and provide survivable mapping of the lightpath topology on the physical topology. We use "total demand volume that can be protected in the lightpath topology" as a measure to evaluate the effectiveness of our solution approach in generating minimum average packet hop-based survivable lightpath topologies. Next, we consider the lightpath topology configuration problem for time-varying traffic in an MPLS routing environment. We propose two approaches to solve the problem: static and dynamic configuration. For static configuration, we present a model to design a single lightpath topology configuration optimized for multiple traffic matrices. The model considers the joint problem of optimal configuration of lightpath topology and optimal routing of LSPs. Finally, for the dynamic configuration, we present a solution approach based on Lagrangian Relaxation and sub-gradient optimization, where the major thrust is to design a lightpath topology optimized for new traffic matrix with fewest possible number of lightpath deletions from the current lightpath topology. Through our studies, we have examined the trade-off between the number of allowed lightpath disruptions and the average packet hop-distance value.
Routing and Wavelength Assignment for WDM-based Optical Networks

Category : Technology & Engineering
Languages : en
Pages : 128
Book Description
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 on novel approaches for the development of routing and wavelength assignment schemes for fault-resilient optical networks, which improve their performance in terms of signal quality, call blocking, congestion level and reliability, without a substantial increase in network setup cost. The book first presents a solution for reducing the effect of the wavelength continuity constraint during the routing and wavelength assignment phase. Further, it reports on an approach allowing the incorporation of a traffic grooming mechanism with routing and wavelength assignment to enhance the effective channel utilization of a given capacity optical network using fewer electrical-optical-electrical conversions. As a third step, it addresses a quality of service provision scheme for wavelength-division multiplexing (WDM)-based optical networks. Lastly, the book describes the inclusion of a tree-based fault resilience scheme in priority-based dispersion-reduced wavelength assignment schemes for the purpose of improving network reliability, while maintaining a better utilization of network resources. Mainly intended for graduate students and researchers, the book provides them with extensive information on both fundamental and advanced technologies for routing and wavelength assignment in optical networks. The topics covered will also be of interest to network planners and designers.

Book Description
With the rapid growth of bandwidth demand from network users and the advances in optical technologies, optical networks with multiterabits per-second capacity has received significant interest from both researchers and practitioners. Optical networks deployment raises a number of challenging problems that require innovative solutions, including net work architectures, scalable and fast network management, resource efficient routing and wavelength assignment algorithms, QoS support and scheduling algorithms, and switch and router architectures. In this book, we put together some important developments in this exiting area during last several years. Some of the articles are research papers and some are surveys. All articles were reviewed by two reviewers. The paper, "On Dynamic Wavelength Assignment in WDM Optical Networks," by Alanyali gives an overview of some issues in the analy sis and synthesis of dynamic wavelength assignment policies for optical WDM networks and illustrates a new method of analysis. The paper by Ellinas and Bala, "Wavelength Assignment Algorithms for WDM Ring Architectures," presents two optimal wavelength assignment algorithms that assign the minimum number of wavelengths between nodes on WDM rings to achieve full mesh connectivity. In the paper, "Optimal Placement of Wavelength Converters in WDM Networks for Parallel and Distributed Computing Systems," Jia et al.
