“…The existing methodologies on logical topology design over WDM networks have focused on minimizing the number of required wavelengths [3,4,5,6], the number of required ADMs (Add-Drop Multiplexers) and transceivers [5,6,7], the blocking probability [8], the number of required paths [9], the total amount of relayed traffic [10,11], the number of required wavelength converters [3,12] and so on, for given traffic matrices. It is well-known that the number of ports (ADMs and transceivers) per WDM node has big impact on hardware costs.…”

Abstract. This paper presents a method for constructing logical topology in multi-hop WDM networks hierarchically. Our logical topology can be built over WDM ring networks with only three ADMs (Add-Drop Multiplexers) and transceivers per node. We aim to realize low-cost WDMs that can be deployed for MANs and LANs. Due to well constructed hierarchical topology, both the maximum distance between two nodes and the number of required wavelengths on each optical fiber are reduced to the logarithmic order of the number of nodes. This contributes to mitigate traffic costs in WDM networks. Furthermore, we propose a node labeling scheme to achieve efficient routing without routing table lookup. From our numerical experiments, we have shown that we could construct a logical topology consisting of 1,000 nodes with a very small diameter and 16 wavelengths in a WDM ring network.

Direction du Patrimoine de I'edition A bstractIn this thesis, we present our recent research work in the area of optical Wavelength Division Multiplexing (WDM) networks, an im portant area which promises to be the focus of ongoing and future research. A WDM network consists of optical wavelength routing nodes interconnected by point-to-point fiber links in an arbitrary topology.WDM allows simultaneous transmission of multiple wavelengths within a single fiber.Although each wavelength can have a transmission capacity up to ten gigabit per second, some traffic streams may require lower bandwidth. To utilize the wavelengths more efficiently, traffic grooming is deployed to share the capacity of a wavelength among users with different bandwidth granularities. In WDM networks, the Routing and Wavelength Assignment (RWA) problem is an im portant issue. Service Differentiation, Quality of Service (QoS), and Fairness Management arestill open research problems in WDM grooming/non-grooming networks. The main contribution of this work is to formulate these problems for both grooming and non-grooming networks in the framework of the Markov Decision Process theory to determine the optimal dynamic wavelength allocation policies. Due to the huge size of the state space for realistic networks, the optimal policy determination is not possible in practice. Hence, heuristic algorithms are proposed with close performance to the optimal solution and lower computational complexity than the optimal. Another contribution of this proposal is to estimate the blocking performance of the system in order to dimension the network links. This work is a fundamental research study on resource management and has great value in future QoS-aware WDM networks.iv Reproduced with
