MCCL: Measurement-based Collective Communication Library
Michele Ferrero, Gabriele Castellano, Paolo Medagliani +3
Collective communication is a critical performance bottleneck in large-scale distributed training. Existing libraries and synthesis frameworks compute open-loop schedules once, ass…
Alternative paths computation for congestion mitigation in segment-routing networks
Sébastien Martin, Youcef Magnouche, Paolo Medagliani +1
In backbone networks, it is fundamental to quickly protect traffic against any unexpected event, such as failures or congestions, which may impact Quality of Service (QoS). Standar…
Virtual Multi-Topology Routing for QoS Constraints
Nicolas Huin, Sébastien Martin, Jérémie Leguay
Multi-topology routing (MTR) provides an attractive alternative to segment routing for traffic engineering when network devices cannot be upgraded. However, due to a high overhead…
Protected load balancing problem: Neural-network based approximation for non-convex optimization
Youcef Magnouche, Sébastien Martin, Jérémie Leguay
Nowadays, centralized Path Computation Elements (PCE) integrate control plane algorithms to optimize routing and load-balancing continuously. When a link fails, the traffic load is…
Scalable Damper-based Deterministic Networking
M. Yassine Naghmouchi, Shoushou Ren, Paolo Medagliani +2
With 5G networking, deterministic guarantees are emerging as a key enabler. In this context, we present a scalable Damper-based architecture for Large-scale Deterministic IP Networ…
