Gestion de réseaux

Résumé

Le Network management, terme anglophone qui signifie gestion de réseaux informatique, se réfère aux activités, méthodes, procédures comme la surveillance du réseau et aux outils de mise en œuvre par l'administrateur réseaux ayant trait à l'exploitation, l'administration, la maintenance et la fourniture des réseaux informatiques. La gestion des réseaux informatiques constitue un problème dont l’enjeu est de garantir au meilleur coût, non seulement la qualité du service rendu aux utilisateurs mais aussi la réactivité dû aux changements et à l'évolution rapide du secteur informatique. Cette gestion des réseaux se définit comme étant l’ensemble des moyens mis en œuvre (connaissances, techniques, méthodes, outils, ...) pour superviser et exploiter des réseaux informatiques et planifier leur évolution en respectant les contraintes de coût, de qualité et de matériel. La qualité de service se décline sur plusieurs critères pour le futur utilisateur, notamment la disponibilité, la performan

The Push Model in Web-Based Network Management

Jean-Philippe Martin-Flatin

The management of IP networks is currently based on the SNMP protocol, and the use of expensive network management platforms designed according to the manager/agent paradigm of the SNMP framework. It uses two different schemes to transfer management data: a request/response protocol for data collection and network monitoring (data polling), and unsolicited push to deliver SNMP notifications. This design is exposed to a number of problems, with regards to the time-to-market of vendor-specific management software, versioning, protocol efficiency, security, etc. In this paper, we propose a novel approach to network management based on the push model. This model is well-known in software engineering, and encountered a large success on the Web recently with the push technologies. It relies on the publish/subscribe/distribute paradigm, and uses a single scheme to transfer all management data. We describe why it is more efficient, in terms of network and systems resources, than the traditional pull model. We also explain in detail how to implement this model with Web technologies to deliver SNMP notifications, to handle events, and to distribute MIB data for network monitoring and data collection.

Over the past few years, network management has steadily evolved from a centralized model, where all the management processing takes place on a single network management station, to distributed models, where management is distributed over a number, potentially large, of nodes. Among distributed models, one, the weakly distributed hierarchical model, has been around for several years, whereas a flurry of new ones, based on mobile code, distributed objects or cooperative agents, have only recently emerged. Which of these techniques will eventually win ? Will several ones have to coexist ? How do they compare to each other ? In order to provide a framework to analyze these issues, this paper presents a comprehensive typology of all network management paradigms known to date, whether they have been successfully implemented already or whether they are still confined to the research community. By comparing these models with those used in another research field, enterprise management, we delineate a common trend of evolution, and attempt to predict what the future holds for network management. Keywords : Distributed Network Management, Organizational Models, Mobile Code, Management by Delegation, Distributed Objects, Intelligent Agents.
