Book Synopsis Routage et allocation de flots avec tolérance aux pannes dans les réseaux Internet nouvelle génération by : Samer Lahoud
Download or read book Routage et allocation de flots avec tolérance aux pannes dans les réseaux Internet nouvelle génération written by Samer Lahoud and published by . This book was released on 2006 with total page 157 pages. Available in PDF, EPUB and Kindle. Book excerpt: Avec l'évolution de l'Internet, le dimensionnement des réseaux coeurs est devenu un enjeu stratégique pour les opérateurs. De nouvelles stratégies sont mises en oeuvre dans les réseaux Internet Nouvelle Génération (ING) pour permettre l'évolution du réseau ainsi que la tolérance aux pannes tout en garantissant un bon retour sur investissement. En particulier, les réseaux ING proposent une architecture à deux couches: un réseau de transport utilisant les technologies optiques comme DWDM et un réseau de données utilisant IP/GMPLS. Dans cette thèse, nous étudions les problèmes d'allocation de flots dans les réseaux de transport. Nous considérons différentes stratégies d'allocation qui privilégient l'équité, la maximisation du volume alloué, ou la minimisation des coûts. Nous étudions différents mécanismes de tolérance aux pannes, notamment la protection par lien et par chemin, et évaluons le partage de la bande passante de secours ainsi que la protection variable. Pour ces différents problèmes, nous proposons des algorithmes d'approximation qui calculent des solutions à un facteur garanti de l'optimal en un temps polynomial. Dans les réseaux de données, nous étudions deux variantes du problème de routage. Nous présentons un algorithme polynomial pour le routage off-line qui inclut différents objectifs d'ingénierie de trafic et fournit une flexibilité de contrôle de la qualité de la solution et une complexité réduite. Dans une autre variante, nous étudions le problème du routage on-line de tunnels à bande passante garantie. Notre approche considère différents mécanismes de tolérance aux pannes et utilise une nouvelle mesure de l'efficacité d'utilisation du réseau.

Book Synopsis Inconsistency Robustness by : Carl Hewitt
Download or read book Inconsistency Robustness written by Carl Hewitt and published by . This book was released on 2015-05-20 with total page 614 pages. Available in PDF, EPUB and Kindle. Book excerpt: Inconsistency robustness is information system performance in the face of continually pervasive inconsistencies---a shift from the previously dominant paradigms of inconsistency denial and inconsistency elimination attempting to sweep them under the rug. Inconsistency robustness is a both an observed phenomenon and a desired feature: Inconsistency Robustness is an observed phenomenon because large information-systems are required to operate in an environment of pervasive inconsistency. Inconsistency Robustness is a desired feature because we need to improve the performance of large information system. This volume has revised versions of refereed articles and panel summaries from the first two International Symposia on Inconsistency Robustness conducted under the auspices of the International Society for Inconsistency Robustness (iRobust http: //irobust.org). The articles are broadly based on theory and practice, addressing fundamental issues in inconsistency robustness. The field of Inconsistency Robustness aims to provide practical rigorous foundations for computer information systems dealing with pervasively inconsistent information."

Book Synopsis Computer Algebra and Polynomials by : Jaime Gutierrez
Download or read book Computer Algebra and Polynomials written by Jaime Gutierrez and published by Springer. This book was released on 2015-01-20 with total page 222 pages. Available in PDF, EPUB and Kindle. Book excerpt: Algebra and number theory have always been counted among the most beautiful mathematical areas with deep proofs and elegant results. However, for a long time they were not considered that important in view of the lack of real-life applications. This has dramatically changed: nowadays we find applications of algebra and number theory frequently in our daily life. This book focuses on the theory and algorithms for polynomials over various coefficient domains such as a finite field or ring. The operations on polynomials in the focus are factorization, composition and decomposition, basis computation for modules, etc. Algorithms for such operations on polynomials have always been a central interest in computer algebra, as it combines formal (the variables) and algebraic or numeric (the coefficients) aspects. The papers presented were selected from the Workshop on Computer Algebra and Polynomials, which was held in Linz at the Johann Radon Institute for Computational and Applied Mathematics (RICAM) during November 25-29, 2013, at the occasion of the Special Semester on Applications of Algebra and Number Theory.
