Description of the tutorial: In this tutorial we will first motivate, introduce, and formally define a number of variants of the traffic grooming and multigranular switching problems in optical wavelength division multiplexed (WDM) networks. We will discuss the relationship of these problems to the more well-known logical topology design and routing and wavelength assignment problems. We will review the latest results on the complexity of the traffic grooming and multigranualr switching problems, and we will discuss the implications of these results to the design of practical algorithms. We will then review a number of algorithms for traffic grooming in ring topologies (with applications to SONET/SDH), star and tree topologies (with applications to WDM access networks), as well as general network topologies (with applications to metro and backbone WDM networks). The tutorial will place emphasis on the design of efficient and practical algorithms with performance guarantees in terms of the network cost.
