Traffic Grooming in Optical WDM Mesh Networks

$Optical networks based on wavelength-division multiplexing (WDM) tech nology offer the promise to satisfy the bandwidth requirements of the Inter net infrastructure, and provide a scalable solution to support the bandwidth needs of future applications in the local and wide areas. In a waveleng- routed network, an optical channel, referred to as a lightpath, is set up between two network nodes for communication. Using WDM technology, an optical fiber link can support multiple non-overlapping wavelength channels, each of which can be operated at the data rate of 10 Gbps or 40 Gbps today. On the other hand, only a fraction of customers are expected to have a need for such a high bandwidth. Due to the large cost of the optical backbone infrastruc ture and enormous WDM channel capacity, connection requests with diverse low-speed bandwidth requirements need to be efficiently groomed onto hi- capacity wavelength channels. This book investigates the optimized design, provisioning, and performance analysis of traffic-groomable WDM networks, and proposes and evaluates new WDM network architectures. Organization of the Book Significant amount of research effort has been devoted to traffic grooming in SONET/WDM ring networks since the current telecom networks are mainly deployed in the form of ring topologies or interconnected rings. As the long-haul backbone networks are evolving to irregular mesh topologies, traffic grooming in optical WDM mesh networks becomes an extremely important and practical research topic for both industry and academia.$

Resource Management and Optimization in Future Optical Networks

$Optical networks are playing an increasingly vital role in scaling up the speed of today's Internet. Wavelength-division multiplexed (WDM) networks traditionally have been expanding capacity by increasing the number of wavelengths and the line rate of each wavelength. Because each wavelength is restricted within a fixed-size spectrum grid, usually 50 GHz, this scaling model has reached a bottleneck. Specifically, the 50-GHz grid cannot accommodate line rates beyond 100 Gb/s. A more flexible wavelength model emerged a few years ago, where each ``wavelength'' is allocated a variable-size grid. This is also known as \emph{Flexgrid}. The size of the allocated spectrum is tailored according to the needs of the optical channel. Higher-bit-rate and longer-distance channels are assigned a larger spectrum. However, this flexibility does not come for free. With optical channels now taking up (sometimes vastly) different spectrum footprints, the spectrum management becomes more challenging. We devote the first half of this dissertation to address the problem of spectrum fragmentation that arises in this context. We first quantify this phenomenon, and then develop preventive and remedial methods to eliminate or alleviate the impacts of fragmentation on service provisioning.In optical access networks, WDM technology has been gradually adopted to scale up the bandwidth. Time- and wavelength-division multiplexed passive optical network (TWDM-PON) has evolved from the pure TDM-PON architecture. Each wavelength is shared in a TDM fashion by multiple optical network units (ONUs). To dynamically adapt this sharing relationship, i.e., which ONUs share which wavelength, according to the changing traffic, we develop mathematical models and heuristic algorithms that together form a comprehensive solution for both the planning and operational stages. The solution optimizes energy usage while maintaining quality-of-service (QoS) requirements. WDM technology also finds an ``unlikely'' application in avionic systems. We propose and design a specialized WDM ring architecture, named AVATAR, to replace the dated copper-based communication infrastructure in today's avionic systems. AVATAR leverages multi-wavelength and spatial reuse properties of a WDM ring through sophisticated packet scheduling. With careful optimization, a base-line, two-wavelength configured AVATAR can achieve a significant performance margin over conventional architectures.$
