Synopsys IP expert Abhinav Khotalya breaks down why AI clusters demand lossless, deterministic networking and how emerging open standards UALink and ESUN are reshaping scale-up fabric design.

Key takeaways

  • AI training workloads require lossless, deterministic networking because tail latency from a single delayed packet can stall an entire accelerator cluster, making conventional best-effort Ethernet insufficient for scale-up fabrics.
  • UALink and ESUM represent complementary approaches to open multi-vendor scale-up networking—UALink enables memory-semantic, tightly coupled accelerator communication, while ESUM extends Ethernet for lossless scale-up with smoother integration into existing infrastructure.
  • Future scale-up fabrics must evolve across four dimensions: higher per-lane speeds (toward 400Gbps), wider domains with higher-radix switches, longer reach via optical interconnects, and smarter in-network compute (INC) to reduce redundant data movement.

Why this matters

As AI clusters scale to thousands of accelerators, the network fabric has become a first-class architectural decision—not background infrastructure—directly determining training efficiency, hardware utilization, and total cost of ownership in next-generation data centers.
