Chapter 5. WDM Network Design -2

Chapter 5. WDM Network Design -2

This chapter focuses on network topology design based on the actual deployment and expected future of optical networks. Practical networks are designed and deployed in topologies that are quite well defined, although the network itself might be spread across vast geographical areas in an extensive way.

From the perspective of the optical layer, networks are classified by their topology as well as their size. Chapter 4, “WDM Network Design -1,” briefly discussed the three topologies: point-to-point networks, rings, and mesh topologies. While designing a network, it is imperative to know which is the most suitable topology for a given cluster of nodes. This decision is important in green field as well as deployed brown field networks, and many factors affect the final outcome of the design.
