DOWNLOAD EBOOKIn this thesis, we are particularly interested in studying the impact of network element failure(s) on network survivability. Namely, we propose and analyze a series of models and schemes to protect and restore the affected services in the networks, thus achieve a better survivability in optical networks. In additions to an introduction of optical networks and a survey of the related work, this thesis first focuses on the problem of fast recovery in Chapter 3. By using the framework of Offset-Time restoration, a novel model based on time-driven scheduling is proposed. It substantially shortens the restoration time and can be applied in both single-link failure and dual-link failure scenarios. Next, capacity reprovisioning, as a simple and efficient mechanism to protect a network against multiple failures, is investigated and a new reprovisioning scheme is proposed in Chapter 4. Finally, the application of capacity reprovisioning in traffic grooming is considered. Two frameworks, i.e., lightpath level reprovisioning and connection level reprovisioning, are proposed in Chapter 5 to improve the survivability of optical networks with grooming capability.

DOWNLOAD EBOOKIn recent years, with the rapid growth of the Internet, the bandwidth demand for data traffic is exploding. Optical networks based on wavelength-division multiplexing (WDM) technology offer the promise to satisfy the bandwidth requirements of the Internet infrastructure. With WDM technology, signals are carried simultaneously on mUltiple wavelengths on a single fiber. WDM provides a practical approach of resolving the mismatch between the fiber ca pacity and the peak electronic processing speed. Mesh-based WDM networks have recently attracted much research and development interest since the In ternet topology is meshed in nature, and more importantly, mesh-based WDM networks are flexible with respect to routing and survivability. This book exam ines the management and survivability issues of mesh-based WDM networks and proposes new WDM network protocols and algorithms that could make telecommunication networks more efficient. Wavelength-routing has been one of the most important technologies to em ploy WDM in backbone networks. In wavelength-routed WDM networks, optical channels, which are referred to as lightpaths, are set up between WDM terminals. Most chapters of this bock are focused on various issues related to wavelength-routed networks, namely, routing and wavelength-assignment, con trol and management, fault management, and wavelength-converter placement. This book also presents an all-optical packet-switched network architecture based on the concept of photonic slot routing. The audience for this book are network designers and planners, research and development engineers active in the field of telecommunications, and students of optical networking at the graduate or senior undergraduate levels.
