The provided text offers a strong critique of Ultra Ethernet while simultaneously promoting Open Atomic Ethernet (OAE), framing the comparison as a conflict between two fundamentally different networking philosophies. The author argues that Ultra Ethernet is primarily focused on selling more bandwidth through complex switch fabrics and firmware, which only statistically achieves low latency and relies on retry logic to mask probabilistic packet loss. Conversely, the text presents OAE as the superior architecture because it utilizes simple, bidirectional atomic links to ensure transactions are provably reversible, deterministic, and that failures are corrected instantly rather than after the fact. The author concludes that while Ultra Ethernet represents the "old order" of opaque, complex networking, OAE offers a transparent, simple mesh that restores determinism to high-performance computing systems.
