15h : accueil et ouverture

15h30 : Présentation invitée de Adrien Lebre (IMT-A/Inria Nantes)

Titre: Fog, Edge, Digital Continuum or Network, the names evolve but the challenges remain the same!

Bio: Adrien Lebre currently holds the position of research director at Inria, where he has been overseeing the network and cloud program. Prior to this role, he was a full professor at IMT Atlantique in Nantes, France. Since 2017, Adrien has led the STACK research group, focusing on large-scale distributed systems, their design, compositional properties, and efficient implementation. More precisely,  his activities have been mainly focusing on the Edge Computing paradigm, in particular in the OpenStack, and more recently,  Kubernetes ecosystems. Adrien Lebre is also strongly involved in several initiatives  related to experiment-driven research on digital infrastructures such as the Slices-RI initiative.  He holds a Ph.D. from Grenoble Institute of Technologies and a habilitation from University of Nantes.  For further information, please visit:   http://stack.inria.fr

Titre: Exploring the Promises and Limitations of GNNs for Network Optimization

Slides
Resumé: Due to their dynamic nature and the multitude of involved parameters, network optimization problems are typically complex. The complexity of these problems is further increased by the distributed nature of these networks, coupled with the need to simultaneously take into account the variety of objectives and constraints, mainly related to the supported services. Conventional optimization methods generally fail to address these multiobjective problems, as they fail to provide scalable and robust solutions capable of dynamically adapting to changing network conditions. To overcome these obstacles, several machine learning-based approaches, and particularly reinforcement learning, have emerged in recent years. Although effective, these approaches are generally unable to grasp the graph topology of the networks and the richness of information, they also pain to generalize the learning, in addition to being unexplainable black boxes, which limits the practical utility of these approaches. In this context, Graph Neural Networks (GNNs) have emerged as a promising approach, leveraging the power of deep learning to process graph-structured data effectively, which is typically needed in several networking problems. This talk will explore the applications of GNNs in network optimization problems such as network tomography for monitoring and virtual service placement for network slicing. We will discuss the ability of GNNs to capture graph structures and apprehend representations directly from network data to enable more efficient and intelligent resource allocation strategies. By exploring both the promises and limitations of GNNs, this talk aims to provide a comprehensive understanding of their applicability in network management, and opens the door for future research directions in this rapidly evolving field.

Titre: Enhancing 6G Through Advanced Routing Mechanisms

Resumé: As the next evolution in wireless communication, the 6G network promises high bandwidth, low latency, massive connectivity, and a special focus on seamless coverage through the integration of terrestrial and non-terrestrial networks. A key component in realizing these advancements is the development of robust, efficient, and intelligent routing mechanisms capable of managing the dynamic, heterogeneous, and densely interconnected topology of 6G architecture. Our research focuses on investigating innovative routing strategies tailored to the unique challenges of 6G networks. This includes dynamic topology management, which involves maintaining optimal routing paths in a network where node positions and link qualities constantly change. Additionally, the routing strategy must ensure ultra-reliable low-latency transmissions to meet the critical Quality of Service requirements of applications such as telesurgery and real-time control systems. By leveraging artificial intelligence, we aim to develop predictive routing algorithms that not only respond to but also predict network dynamics, optimizing path selection beyond the capabilities of traditional protocols.
