This book was released on 2002 with total page pages. Available in PDF, EPUB and Kindle. 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.

Available in PDF, EPUB and Kindle. Book excerpt: Emerging applications today require higher data rates. The end users by consuming these applications are contributing to the rapidly growing future Internet traffic. This results in dramatic increase in data rate demand day by day. The present day networks based on IP, are constantly challenged to meet this demand. Even with adding complex processing for the routing/switching computation, IP is not able to avert the bottleneck. The major contributing factor to the high operating cost of the present day networks is the processing of the network nodes and not the long-haul transmission. Hence, there are two main drawbacks with present day networks — power consumption and scalability. Optical networking on the other hand, is capable of dramatic data rate increases in the next decade. Also, Optical networking is playing prominent roles in novel network architectures and has become a strong replacement to the traditional electronic networking. To unleash its potential and to create robust networks, the advanced optical network architectures have to be studied and improvements should be proposed. In this dissertation, three advanced optical network architectures are analyzed and solutions for provisioning, signaling protocols and algorithms are proposed. The advanced network architectures are studied: 1) Optical Flow Switching (OFS) networks 2) Generalized Multi- Protocol Label Switching (GMPLS) enabled WDM networks and 3) multilayer networks. In the OFS network architecture construct, the problem of scheduling and contentions are analyzed. In the GMPLS enabled WDM networks, the problem of race conditions and the concept of trading wavelengths for better OSNR are analyzed. In the study on multilayer networks consisting of three layers — IP/MPLS, OTN and DWDM, a controller with three optimization strategies is proposed to provision/coordinate across the layers.

This book was released on 2006 with total page 148 pages. Available in PDF, EPUB and Kindle. Book excerpt: The evolution of the Internet has proved that packet switching, regardless of the underlying transport technology, is the most flexible and robust solution for the present and future dynamic network traffic. Service providers are now evolving their complex networks toward a simpler architecture, based on a single, highly available intelligent packet layer residing on optical transport layer. At the center of this new architecture is the Internet Protocol/Multi-Protocol Label Switching (IP/MPLS) routing platform directly over wavelength division multiplexing (WDM) layer. In these regard, optical packet switching (OPS) appears to be the most prominent candidate transport solution that can seamlessly integrate electrical and optical layers by transferring certain switching functionality from electronics to optics, thus alleviating unnecessarily slow and expensive optical-electrical-optical conversions and signal processing at the switching node.
