Thesis
  1. D. Coudert. Algorithmique et optimisation de réseaux de communications optiques. PhD thesis, Université de Nice Sophia-Antipolis (UNSA), Décembre 2001. [POSTSCRIPT ]
    Abstract:
    This thesis deals with optical communication networks, especially free space optical networks and optical fiber networks. First we address the design of free space optical networks using the Optical Transpose Interconnection System (OTIS) architecture defined in [MMHE93]. We give a model of these networks with H(p,q,d) digraphs which we characterize. We take a specific interest in isomorphisms between these digraphs and well known digraphs (de Bruijn, Kautz and other alphabet graphs). We develop a family of alphabet digraphs which includes a large number of digraphs isomorphic to the de Bruijn and use it to obtain an optimal design of the de Bruijn with OTIS, in terms of minimizing the number of lenses. Then, we study a family of networks modeled by directed hypergraphs and called stack-Kautz, for which we provide routing algorithms and control protocols. In a second part we address the problem of WDM network survivability using protection. This problem consists in using precomputed and dedicated resources in order to ensure traffic continuity if a bundle of fibers breaks down. We describe numerous strategies for protecting the instance and the network. We go more deeply into subnetwork protection where protection resources are shared by sets of request describing a specific subnetwork (circuit). We give an optimal solution to this problem when the network is a cycle and the requests realize the All-to-All pattern.

    Abstract:
    In this paper we present a simple model for satellite constellations with polar orbits and inter-satellite links. This model is used to propose and study two algorithms for routing and re-routing communications, which aim at improving the quality of service for long communications. In order to study these algorithms, we have developed a satellite constellation simulator. Some of its results are presented.

    Abstract:
    This paper considers the design of a survivable WDM network based on covering the initial network with sub-networks, which are protected independently from each other. We focus on the case where the optical WDM network is a ring, there are requests between any pair of vertices and the covering is done with small cycles. This problem can be modelled as follows: Find a covering of the edges of a logical graph $I$ (here the complete graph $K_n$) by subgraphs $I_k$ of a certain kind (here cycles $C_k$ of length $k$), such that, for each $I_k$, there exists in the physical graph $G$ (here $C_n$) a disjoint routing of the edges of $I_k$. The aim is to minimize the number of subgraphs $I_k$ in the covering. We give optimal solutions for that problem.

    Abstract:
    We study the following Constrained Bipartite Edge Coloring (CBEC) problem: We are given a bipartite graph G(U,V,E) of maximum degree l with n vertices, in which some of the edges have been legally colored with c colors. We wish to complete the coloring of the edges of G minimizing the total number of colors used. The problem has been proved to be NP-hard event for bipartite graphs of maximum degree three [5].

    Abstract:
    This paper addresses the natural relaxation of the path coloring problem, in which one needs to color directed paths on a symmetric directed graph with a minimum number of colors, in such a way that paths using the same arc of the graph have different colors. This classic combinatorial problem finds applications in the minimization of the number of wavelengths in wavelength division multiplexing (wdm) all-optical networks.

    Abstract:
    In this paper, we address multifiber optical networks with Wavelength Division Multiplexing (WDM). Assuming that the lightpaths use the same wavelength from source to destination, we extend the definition of the well-known Wavelength Assignment Problem (WAP), to the case where there are $k$ fibers per link, and $w$ wavelengths per fiber are available. We then develop a new model for the $(k,w)$-WAP, based on conflict hypergraphs -Conflict hypergraphs more accurately capture the lightpath interdependencies- , generalizing the conflict graphs used for single-fiber networks. By relating the $(k,w)$-WAP with the hypergraph coloring problem, we prove that the former is \npc, and present further results with respect to the complexity of that problem. Finally, we analyze the practical performances of two methodologies based on hypergraph coloring, on existing backbone networks in Europe and in the USA. The first relies on an integer programming formulation and the second consists of a heuristic based on a randomized algorithm. We consider the two natural optimization problems that arise from the $(k,w)$-WAP : the problem of minimizing $k$ given $w$, and that of minimizing $w$ given $k$

    abstract = {In this paper, we address multifiber optical networks with Wavelength Division Multiplexing (WDM). Assuming that the lightpaths use the same wavelength from source to destination, we extend the definition of the well-known Wavelength Assignment Problem (WAP), to the case where there are $k$ fibers per link, and $w$ wavelengths per fiber are available. We then develop a new model for the $(k,w)$-WAP, based on conflict hypergraphs -Conflict hypergraphs more accurately capture the lightpath interdependencies- , generalizing the conflict graphs used for single-fiber networks. By relating the $(k,w)$-WAP with the hypergraph coloring problem, we prove that the former is \npc, and present further results with respect to the complexity of that problem. Finally, we analyze the practical performances of two methodologies based on hypergraph coloring, on existing backbone networks in Europe and in the USA. The first relies on an integer programming formulation and the second consists of a heuristic based on a randomized algorithm. We consider the two natural optimization problems that arise from the $(k,w)$-WAP : the problem of minimizing $k$ given $w$, and that of minimizing $w$ given $k$},

    Abstract:
    We study the dipath-coloring problem in bounded degree and treewidth symmetric digraphs, in which one needs to color the dipaths with a minimum number of colors, in such a way that dipaths using the same arc have different colors. This classic combinatorial problem finds applications in the minimization of the number of wavelengths in wavelength division multiplexing (WDM) all optical networks. In this paper, we prove that finding an optimal fractional coloring of such dipaths is polynomial. Our solution is constructive, i.e. we give an effective polynomial algorithm for the problem above. We also show some relationships between the integral and fractional problems, prove some polynomial instances of the coloring problem, and derive a $1 + 5/3e$ approximation for the \wdm problem in symmetric directed trees, where $e$ is the classical Neper constant, improving on previous results. Finally we present computational results suggesting that fractional coloring is a good oracle for a branch and bound strategy for coloring dipaths in symmetric directed trees and cycles.
