Book excerpt: Today, the phenomenal traffic growth of Internet leads to the dramatic expansion of the transmission lines in the Internet Protocol (IP) network. Fibre optics as the key of the future transmission networks has evolved to provide almost limitlel!ls information carrying capacity via its Wavelength Division Multiplexing (WDM) technology. However, the relatively sluggish development in switching technology which still operates in electronics domain might creates bottleneck in various part of the network. Thus, the concept of All-Optical Network has been introduced. Here a lot of approaches have been proposed to bring IP closer to the optics technology such as IP over WDM. On the other hand, IP technology itself has evolved from pure connectionless system to connection-oriented in order to cope with the Quality of Service (QoS) demanded by the end users. Thus, the concept of Multi Protocol Label Switching (MPLS) has been standardized to achieve this. In this thesis, connection-oriented Optical Label Switching (OLS) network implementing MPLS system has been proposed as aviable and future proof network architecture. However since this is a relatively new area, comprehensive studies on this subject are yet to be available. Resource contention resolutions have been fairly studied in OLS connectionless network, however the percentage of packets arriving in sequence which is an important performance parameter in connection-oriented network has been neglected. In the network layer study of this research project, optical buffering via fibre delay lines (FDL) has been demonstrated as effective in mitigating packet losses but poor in assuring in-sequence packets arrival. Reduced Length Multistage FDL buffering and wavelength conversion have been proposed and demonstrated as the viable contention resolution techniques which assure higher degree of in-sequence packets arrival. Another important research area in OLS is on devising technique to accomplish label switching in each OLS network node. In the physical layer study of this project, Parallel Lambda technique has been introduced and demonstrated as a simple and effective way to facilitate label switching. The label at lower bit rates than the payload is generated at a few nanometer above the payload operating wavelength but within the same WDM multiplexer channel. This label travels together in parallel with the payload throughout the network and manages label switching at each node while maintaining acceptable power levels and bit error rates. In conclusion, Optical Label Switching network implementing MPLS system can provide a better solution to the realization of future all-optical networks. Beside its potential in providing higher network throughput due to its smallest switching granularity, it also provides quality in its output by assuring high degree of in- sequence packets arrival. Finally by adopting Parallel Lambda technique in the switch architecture a simple and efficient label switching mechanism can be realized.

This book was released on 2002 with total page 454 pages. Available in PDF, EPUB and Kindle. Book excerpt: Optical communications networks are becoming increasingly important as there is demand for high capacity links. Dense wavelength division multiplexing (DWDM) is widely deployed at the core networks to accommodate high capacity transport systems. Optical components such as optical amplifiers, tunable filters, transceivers, termination devices and add-drop multiplexers are becoming more reliable and affordable. Access and metropolitan area networks are increasingly built with optical technologies to overcome the electronic bottleneck at network edges. New components and subsystems for very high speed optical networks offer new design options.The proceedings of the First International Conference on Optical Communications and Networks present high quality recent research results in the areas of optical communications, network components, architectures, protocols, planning, design, management and operation.

This book was released on 2009-06-20 with total page 224 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides a broad overview of IP over WDM technologies, as seen by a group of experts participating in the e-Photon/ONeC and BONE Networks of Excellence funded within the VIth and VIIth Research Framework Programmes (FP6 and FP7) of the European Union. Both Networks of Excellence are aimed at the integration of research teams active on optical networks at a pan-European level, with the creation of virtual centers of excellence in optical networks, te- nologies, and services. The working groups on optical core networks gathered about a 100 researchers from more than 20 universities and research institutions in Europe. The multifaceted viewpoints available in this community on the current state and future evolution of large WDM networking infrastructures are reported in this book. The book is organized in chapters, with chapter editors, listed on pp–, having the responsibility to collect and harmonize contributions by different - search groups. The whole work was made possible by the coordination efforts of Javier Aracil and Franco Callegati, leaders, at the time when the book writing was begun, of the working groups on optical core networks and on optical burst swit- ing in e-Photon/ONeC. We are thankful to them for their efforts. We hope that this manuscript will serve as a valuable reference for students and practitioners in the ?eld of optical networking.

This book was released on 2003 with total page 48 pages. Available in PDF, EPUB and Kindle. Book excerpt: As rapid Internet growth continues, global communications becomes more dependent on Internet availability for information transfer. Recently, the Internet Engineering Task Force (IETF) introduced a new protocol, Multiple Protocol Label Switching (MPLS), to provide high-performance data flows within the Internet. MPLS emulates two major aspects of the Asynchronous Transfer Mode (ATM) technology. First, each initial IP packet is 'routed' to its destination based on previously known delay and congestion avoidance mechanisms. This allows for effective distribution of network resources and reduces the probability of congestion. Second, after route selection each subsequent packet is assigned a label at each hop, which determines the output port for the packet to reach its final destination. These labels guide the forwarding of each packet at routing nodes more efficiently and with more control than traditional IP forwarding (based on complete address information in each packet) for high-performance data flows. Label assignment is critical in the prompt and accurate delivery of user data. However, the protocols for label distribution were not adequately secured. Thus, if an adversary compromises a node by intercepting and modifying, or more simply injecting false labels into the packet-forwarding engine, the propagation of improperly labeled data flows could create instability in the entire network. In addition, some Virtual Private Network (VPN) solutions take advantage of this 'virtual channel' configuration to eliminate the need for user data encryption to provide privacy. VPN's relying on MPLS require accurate label assignment to maintain user data protection. This research developed a working distributive trust model that demonstrated how to deploy confidentiality, authentication, and non-repudiation in the global network label switching control plane. Simulation models and laboratory testbed implementations that demonstrated this concept were developed, and results from this research were transferred to industry via standards in the Optical Internetworking Forum (OIF).

Available in PDF, EPUB and Kindle. Book excerpt: Multi Protocol Label Switching is an emerging technology used for fast transmission of data and avoid congestion. This book focusses on MPLS complete study of its working and different types of VPNs that can be implemented. This book also focusses on other protocols which run at the backbone and their implementation and working in details for better understanding. Multi protocol label switching works on the labels and these labels can be used to find path for the packets within the networks. There are different planes which are used to find the path for the routers. Thus enable router to find the path in an efficient manner than traditional routing protocol.

Book excerpt: "The last decade has witnessed an explosive growth in internet protocol, packet based traffic. Although long-haul fiber backbone networks provide capacities on the order of Tb/s, a bottleneck at the access network has arisen due to electronic domain signal processing. Recent developments in optical multiprotocol label switching (MPLS) access networks promise to remove this bottleneck and allow Gb/s capacities per user and satisfy foreseeable future bandwidth requirements." --
