Pour localiser ces services, une solution efficace de d\u00e9couverte de services est essentielle. Cette solution doit g\u00e9rer les descriptions h\u00e9t\u00e9rog\u00e8nes des services, leur forte configurabilit\u00e9, et leur nature essentiellement group\u00e9e. Les \u00ab services hautement configurables \u00bb sont ceux dont les propri\u00e9t\u00e9s peuvent varier fr\u00e9quemment et sont interd\u00e9pendantes. Les \u00abservices purement group\u00e9s\u00bb se r\u00e9f\u00e8rent \u00e0 ceux qui ne sont pas disponibles \u00e0 l’unit\u00e9 mais uniquement en package. La d\u00e9couverte de services ne doit pas seulement permettre de localiser les services ; elle doit aussi offrir l’accompagnement n\u00e9cessaire aux clients pour ajuster leurs demandes quand il n’y a pas de correspondance exacte avec les services disponibles. Dans cette th\u00e8se, nos objectifs sont de (i) d\u00e9crire les services de r\u00e9seau en cloud en prenant en compte leur nature configurable et group\u00e9e, (ii) structurer leurs descriptions pour faciliter leur d\u00e9couverte, et (iii) assister les clients dans l’ajustement de leurs demandes pour am\u00e9liorer les r\u00e9sultats de la d\u00e9couverte de services. Pour le premier objectif, nous proposons un mod\u00e8le qui d\u00e9crit les services de r\u00e9seau en cloud \u00e0 base de leurs propri\u00e9t\u00e9s fonctionnelles et non fonctionnelles tout en consid\u00e9rant leurs particularit\u00e9s. Pour le second objectif, nous introduisons une structure d’indexation destin\u00e9e \u00e0 organiser de mani\u00e8re hi\u00e9rarchique les descriptions de ces services. Enfin, pour le troisi\u00e8me objectif, nous d\u00e9veloppons une m\u00e9thode bas\u00e9e sur la relaxation des demandes pour guider les clients dans la reformulation de leurs requ\u00eates afin de mieux correspondre aux services disponibles. Abstract :<\/strong><\/p>\n\n\n\n The increasing reliance on cloud network services is becoming a preferred option for customers seeking to interconnect their distributed devices without relying on their own physical networking infrastructures. To locate cloud network services, a service discovery solution is required. This solution must address the heterogeneous descriptions of the services, their high configurability, and their inherently bundled nature. By \u00ab\u00a0highly configurable services\u00a0\u00bb, we refer to those whose properties are variable (frequently change) and dependent on other properties. \u00ab\u00a0Purely bundled services\u00a0\u00bb refer to those that cannot be consumed individually but rather as a package deal. The role of service discovery should go a step beyond simply locating services; it should also provide customers with the necessary support to modify their requests when the available services do not exactly match their needs. In this thesis, our objectives are to (i) accurately describe cloud network services while handling their highly configurable and bundled nature, (ii) organize their descriptions to enhance their discovery, and (iii) help customers modify their requests to get better outcomes in service discovery. To accomplish the first objective, we propose a model that describes cloud network services based on their functional and non-functional features, while addressing their specificities. For the second objective, we present an indexing structure that organizes the descriptions of cloud network services in a hierarchical manner. Finally, for the third objective, we propose a request relaxation-based approach that assists customers in rewriting their requests to better match the services they seek.<\/p>\n","protected":false},"excerpt":{"rendered":" L’Ecole doctorale : Ecole Doctorale de l’Institut Polytechnique de Paris et le Laboratoire de recherche SAMOVAR – Services r\u00e9partis,
