    Flux: Optimal Scheduling of Optical Circuit Switches for LLM Training

    Arno Troch, Seyyidahmed Lahmer, Abubakr Nada, Jeroen Famaey, Michael Peeters

    cs.NI · cs.DC

    Optical Circuit Switching (OCS) offers high bandwidth density and energy efficiency for LLM training, but incurs a non-negligible reconfiguration delay. Prior work typically schedules optical circuit switches independently of compute, using aggregate traffic demand to determine which circuits to provision and when. We argue that this separation creates a fundamental inefficiency: reconfigurations that ignore the compute timeline can stall...

    Lizard: Bandwidth-Adaptive Real-Time Video Analytics through Content-Aware Packet Discarding at Last-Mile Edge Routers

    Shan Yu, Yu Chen, Yifan Qiao, Sheng Zhang, Ravi Netravali, Harry Xu

    cs.NI · cs.DC

    The timeliness and accuracy of edge-based video analytics can be hindered by drastic reductions in available bandwidth (ABW) at last-mile edge routers, causing prolonged queuing delays. This work proposes Lizard, a system that leverages video-content-aware packet discarding to mitigate the negative effects of drastic ABW degradation that may frequently occur at a last-mile edge router by judiciously discarding packets that contain frame...
