1.6T Ethernet Packet Loss Problem Solved: PHY-Layer Buffer Exhaustion with MAC-Layer Credit-Based Flow Control
Introduction: As network fabrics scale to support next-generation AI clusters and workloads, the industry is confronting a harsh physical-layer reality. Recent laboratory benchmarks evaluating 1.6 Terabit Ethernet (1.6T) data streams confirm that under saturated, wire-speed workloads, traditional packet-forwarding logic triggers instantaneous Physical layer (PHY) memory buffer exhaustion. Recently released laboratory validation data provides the first… Read more
