Modélisation des chaines de services hautement disponibles

Abstract

The variety of virtual service deployment platforms as well as the variety of virtual service description models used by these platforms can create ambiguity for the service chains designers. Thus, the need for a virtual service description tool by service requesting clients and orchestrators triggers the need for a virtual service description model. This thesis proposes a solution coming from the need to have a standard and generic model grouping together the functionalities of the service function chain and facilitating their modelling. This solution consists of designing a generic description model of SFCs allowing both the graphic design of service functions chains and their adaptation to existing deployment platforms. The work done in this thesis is carried out along two axes: the first is the creation of the generic description model of SFCs as well as the editor allowing their graphic design. The second axis is the implementation of a transformation tool allowing the adaptation of these SFCs to the TOSCA and NFV deployment models. The validation of this work was carried out based on the implementation and testing environment of the editor and the transformation tool.
