The networking industry loves inflection points. Over the years, we have had many new compute models that require the network to evolve. For as long as I can remember, the holy war between InfiniBand and Ethernet was fought on a relatively simple battlefield: throughput versus ubiquity. But as artificial intelligence workloads scale from tens of thousands of processors to massive clusters approaching the million-graphics-processing-unit mark, the network is fundamentally changing. It is no longer just a standalone infrastructure layer; it has become the critical backplane of a tightly integrated AI supersystem.
