Description of the thesis topic

The aim of the proposed thesis subject is to contribute to the deployment of communication protocols (more precisely relating to the “Transport” level) adapted to the needs of the supported applications, this by taking advantage of new opportunities on the Internet in terms of virtualization. Taking advantage of new “softwarization” technologies (SDN, NFV, etc.), the work we are currently carrying out has made it possible to conceptualize the notion of “virtual transport layer (VTL)” aiming to allow dynamic (re) -configuration and transparent for the applications (both current and future), of the most appropriate mechanisms for satisfying their functional and non-functional needs, this taking advantage of / taking into account the opportunities / constraints of the new deployment ecosystem, both at the machine level and datacenter and network. The thesis subject aims to continue this work from several angles: on the one hand in terms of development of proofs of concepts of the current VTL proposition, and on the other hand in terms of extension of the functionalities and the architectural choices structural and behavioral) of the VTL, with a view to increasing the degree of autonomy (dynamic discovery of opportunities and constraints, automatic learning to guide the choice of compositions / deployments, etc.). The applications envisaged to demonstrate the merits of the targeted solution will be located particularly in the field of multimedia, in the current Internet and its extensions to IoT.

Work Context

The work will be carried out within the "Service and Architectures for Advanced Networks" team (SARA) of the Laboratory for Analysis and Architecture of Systems (LAAS-CNRS), located in Toulouse. The LAAS is a specific unit of the CNRS attached to the Institute of Engineering and Systems Sciences (INSIS) and the Institute of Information Sciences and their Interactions (INS2I). The research carried out at LAAS-CNRS aims at a fundamental understanding of complex systems while considering the use that can result from it. Conversely, many societal or industrial issues, for example in the fields of aeronautics, space, health, energy or communication networks raise fundamental questions which in turn feed the inspiration of researchers. The work of the SARA team concerns new generation communication networks and systems, and their applications. They are increasingly present in our daily activities and today play a critical role in all sectors of activity. With the rise of the Internet of Things and Edge Computing, the proliferation of radio access technologies (especially 5G and LPWAN networks) and a strong trend towards network virtualization, the importance of these systems will further grow. These developments will also lead to an unprecedented complexity of networks, the mastery of which already poses real conceptual difficulties. In this context, the team's work aims at real methodological advances allowing to master the design, deployment, planning, supervision and control of communication networks and services. Our contributions relate in particular to the development of methods, models and tools as well as to the proposal of architectures, protocols and services.
