Time Appliances Project Call

Abstract: In 2025, the Open Atomic Ethernet (OAE) project, within the Open Compute Project Time Appliance initiative, made substantial progress toward re-establishing Ethernet as a coherent, deterministic, and trustworthy foundation for modern computing systems. Conventional Ethernet links are treated as probabilistic channels, pushing correctness and liveness up the stack and forcing timeout-and-retry behaviors that amplify uncertainty, tail latency, and failure ambiguity. OAE challenges this model by making links transactional, directly observable, and amenable to formal reasoning. This year-end talk reviews OAE milestones from January through December, including formalization of link-centric atomic semantics and deterministic token transfer, timeout-free failure detection via reversible echo and triangle supervision, and zero-administration Layer-2 bring-up. We summarize advances in Reliable Link Failure Detection (RLFD) and Perfect Information Feedback (PIF), along with graph-based topology discovery spanning chiplet-scale and datacenter-scale fabrics. We also cover secure bring-up using PUF-derived identities and message-free key establishment, including multi-packet authenticated encryption for link establishment. The presentation closes with lessons learned from applying OAE principles to AI/ML training infrastructure, chiplet interconnect management, and large-scale distributed systems. The results highlight how eliminating timeout-and-retry at the link layer enables faster fault detection, stronger correctness guarantees such as exactly-once and atomic snapshots, and more predictable system behavior. We conclude with implications for Ethernet standardization and outline the work planned for 2026 Speaker: Paul Borrill is the founder and CEO of DÆDÆLUS, a company focused on making the world safe for transactions. He has spent his career in system architecture, performance, and storage, with leadership and technical roles at Sun Microsystems, Quantum, VERITAS, and Apple. His long-standing focus on dependable computing began early—he designed an experiment that flew on the last successful Challenger mission—and this has shaped his work ever since. Paul is now on his third startup, pursuing a vision for simple, reliable, and secure micro-datacenters. He is also a co-founder of the IEEE Hot Interconnects Symposium and the Storage Networking Industry Association, or SNIA. In addition to his industry work, Paul founded ItsAboutTime.club, a multidisciplinary forum exploring the nature of time and causality across physics, computer science, mathematics, and philosophy. As it grew beyond two thousand participants, the discussions transitioned into a smaller, invitation-only weekly forum called Mulligan Stew, bringing together experts in databases and distributed systems.
