| Traffic Grooming in Optical WDM Mesh Networks captures the state-of-the-art in the design and analysis of network architectures, protocols, and algorithms for implementing efficient traffic grooming in optical WDM mesh networks. Key topics include: - Static traffic grooming - Dynamic traffic grooming - Grooming models and policies - Grooming node architectures - Design of grooming network - Traffic grooming in next-generation SONET/SDH networks The authors investigate traffic-grooming problems in optical WDM mesh networks from various aspects. They cover static and dynamic traffic grooming, as well as grooming policies for both environments. A fundamental graph model for traffic-grooming networks is proposed. A variety of grooming-node architectures are examined and their performances compared. Design of traffic-grooming networks using different node architectures is explored, and traffic grooming in next-generation SONET/SDH networks is presented.
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. Chapter 1 gives an overview of traffic grooming in optical WDM network. The remaining chapters focus on traffic grooming in WDM mesh networks only.
In a wavelength-routed WDM network, instead of asking for the capacity of a full wavelength channel, a connection may only require a small fraction of the wavelength capacity. Chapter 2 investigates the problem of grooming static traffic demands, i.e., a set of pre-known low-speed traffic streams, onto highcapacity lightpaths in a WDM-based optical mesh network. A mathematical formulation of this problem is presented and several connection-provisioning heuristics are also investigated.
