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.
