 Thesis
1. H. Rivano. Algorithmique et télécommunications : coloration et multiflot approchés et applications aux réseaux d'infrastructure. PhD thesis, Université de Nice-Sophia Antipolis, November 2003. [WWW ] [PDF ] [POSTSCRIPT ]
Abstract:
Cette thèse s'intéresse aux problématiques fondamentales d'optimisation combinatoire qui se dégagent de la modélisation structurelle et algorithmique du dimensionnement des réseaux d'infrastructure de télécommunication. L'optimisation de ces réseaux est essentielle aux opérateurs de télécommunication, qui demandent la garantie d'une exploitation efficace des ressources déployées. Nous donnons une nouvelle modélisation des réseaux optiques WDM multifibres. En considérant un routage agrégé au niveau des câbles, nous optons pour une nouvelle lecture des contraintes d'affectation de longueurs d'onde fondée sur des conflits de groupe. Nous étudions aussi le problème de coloration de chemins, issu de l'affectation de longueurs d'onde dans les réseaux optiques monofibres. Nous développons, pour la relaxation linéaire de ce problème, un algorithme polynomial efficace dans les arbres de degré borné, puis, par extension, dans les graphes de largeur arborescente bornée. Nous majorons le coût d'une telle coloration dans les arbres binaires et donnons une (1+5/(3e)+o(1))-approximation aléatoire pour la coloration entière dans les arbres de degré borné, ce qui améliore le meilleur algorithme connu pour ce cas. Nous présentons enfin des avancées algorithmiques pour les problèmes de multiflot entier et fractionnaire. Nous donnons un algorithme d'arrondi aléatoire incrémental pour l'approximation du multiflot entier. Motivés par le besoin d'un calcul rapide de multiflot fractionnaire pour l'algorithme précédent, nous nous intéressons aux approximations combinatoires de ce problème. En employant des techniques de calcul dynamique des plus courts chemins, nous améliorons l'un des meilleurs algorithme de la littérature.

Note: ISBN: 81-271-0028-5. [PDF ] [POSTSCRIPT ]
Abstract:
This paper has a double purpose. In the first part of the paper we give an overview of different aspects of graph theory which can be applied in communication engineering, not trying to present immediate results to be applied neither a complete survey of results, but to give a flavor of how graph theory can help research in optical networks. The second part of this paper is a detailed example of the usage of graph theory, but it is also a complete survey of recent results in minimization of the number of add--drop multiplexers (ADMs) required in a WDM ring with traffic grooming.

Abstract:
A branch and bound algorithm is proposed for solving integer separable concave problems. The method uses Lagrangian duality to obtain lower and upper bounds. We show that the dual program of a separable concave problem is a linear program. Moreover, we identify an excellent candidate to test on each region of the branch and we show an optimality sufficient condition for this candidate. Preliminary computational results are reported.

Abstract:
This paper considers the cycle covering of complete graphs motivated by the design of survivable WDM networks, where the requests are routed on sub-networks which are protected independently from each other. The problem can be stated as follows~: for a given graph $G$, find a cycle covering of the edge set of $K_n$, where $V(K_n) = V(G)$, such that each cycle in the covering satisfies the disjoint routing constraint (DRC), relatively to $G$, which can be stated as follows~: to each edge of $K_n$ we associate in G a path and all the paths associated to the edges of a cycle of the covering must be vertex disjoint. Here we consider the case where $G = C_n$, a ring of size $n$ and we want to minimize the number of cycles in the covering. We give optimal solutions for the problem as well as for variations of the problem, namely, its directed version and the case when the cycle length is fixed to 4.

Abstract:
In this paper, we study multi-fiber optical networks with wavelength division multiplexing (WDM). We extend the definition of the well-known Wavelength Assignment Problem (WAP) to the case of k fibers per link and w wavelengths per fiber, generalization that we will call (k,w)-WAP. We develop a new model for the (k,w)-WAP based on conflict hypergraphs. Furthermore, we consider two natural optimization problems that arise from the (k,w)-WAP: minimizing the number of fibers k given a number of wavelengths w, on one hand, and minimizing w given k, on the other. We develop and analyze the practical performance of two methodologies based on hypergraph coloring.

Note: ON07-3. [PDF ] [POSTSCRIPT ]
Abstract:
We address the problem of traffic grooming in WDM rings with all-to-all uniform unitary traffic. We want to minimize the total number of SONET add-drop multiplexers (ADMs) required. We show that this problem corresponds to a partition of the edges of the complete graph into subgraphs, where each subgraph has at most $C$ edges (where $C$ is the grooming ratio) and where the total number of vertices has to be minimized. Using tools of graph and design theory, we optimally solve the problem for practical values and infinite congruence classes of values for a given $C$, and thus improve and unify all the preceding results. We disprove a conjecture of Chiu and Modiano (IEEE/OSA JLT 2000) saying that the minimum number of ADMs cannot be achieved with the minimum number of wavelengths, and also another conjecture of Hu (OSA JON 2002).

Abstract:
The design of WDM optical networks is an issue for telecom operators since the spreading of this technology will not occur unless enough performance guarantees are provided. Motivated by the quest for efficient algorithms for the Routing and Wavelength Assignment problem (RWA), we address approximations of the fractional multicommodity flow problem which is the central part of a complex randomized rounding algorithm for the integral problem. Through the use of dynamic shortest path computations and other combinatorial approaches, we improve on the best known algorithm. We also provide directions for further improvements.

In Parallel and Distributed Processing Symposium (IPDPS), pages 8, April 2003. IEEE Computer Society Press. [WWW ] [PDF ]
Abstract:
We present a technique to evaluate the approximation ratio on random instances of the Minimum Energy Broadcast Problem in Ad-Hoc Radio Networks which is known to be NP-hard and approximable within 12. Our technique relies on polynomial-time computable lower bound on the optimal cost of any instance. The main result of this paper is that the approximation ratio has never achieved a value greater than 6.4. Furthermore, the worst values of this ratio are achieved for small network sizes. We also provide a clear geometrical motivation of such good approximation results.

This work is motivated by the need for approximation algorithms for the integral multicommodity flow problem which arise in numerous optimization scenarios, including the design of telecommunication networks. We improve on one of the most efficient known combinatorial approximation algorithm for fractional multicommodity flow by using an incremental approach. This approach is validated by experimental results, which show a significant speed-up.

Abstract:
We study 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: This generalization is called the (k,w)-WAP. We 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 NP-complete, and present further results with respect to the complexity of that problem. 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. We develop and analyze the practical performances of two methodologies based on hypergraph coloring, one for each of the two optimization problems, on existing backbone networks in Europe and in the USA. The first methodology relies on two heuristics based on a randomized approximation algorithm and the second consists on an integer programming formulation.

Abstract:
There are two fundamental technology issues that challenge the robustness of IP backbones. First, SONET protection is gradually being removed because of its high cost (while SONET framing is kept for failure detection purposes). Protection and restoration are provided by the IP layer that operates directly over a DWDM infrastructure. Second, ISPs are systematically forced to use the shortest distance path between two Points of Presence in order to meet their promised SLAs. In this context, IP backbones are extremely vulnerable to fiber cuts that can bring down a significant fraction of the IP routes. We propose two solutions (an ILP model and a heuristic algorithm) to optimally map a given IP topology onto a fiber infrastructure. The version of the mapping problem that we address incorporates a number of real constraints and requirements faced by carriers today. The optimal mapping maximizes the robustness of the network while maintaining the ISP's SLA delay requirements. In addition, our heuristic takes into consideration constraints such as a shortage of wavelengths and priorities among POPs and routes. The heuristic is evaluated on the Sprint backbone network. We illustrate the tradeoffs between the many requirements.
