Static WDM network planning with TDM channel partitioning [link]Website  abstract   bibtex   
In this paper a new solution for the routing, fiber, wave-length and time slot assignment problem (RFWTA) is proposed for a static WDM network. A set of electronic requests characterized by different bit-rates are groomed on lightpaths by a TDM-scheme, designing the logical topology so that the lightpath bandwidth is efficiently exploited. An efficient TDM-based mapping of low granularity electronic connection requests achieves savings in fiber deployment to accommodate a given static traffic. Our analysis comprises two different network layers. First, all the electronic requests are mapped on the logical topology and groomed to obtain the set of lightpath connection requests. Secondly, such requests are routed and fibers and wavelengths are jointly assigned. We adopt the concept of Multihop Lightpath to constrain the number of Time Slot Switching (TSS) operations for each connection request. After introducing our design approach, we discuss the optimization of two case-study networks under various conditions and we analyze the results. © IFIP International Federation for Information Processing 2004.
