Building the Agentic AI Overlay Reference Architecture – Draft Framework & Community Input
The Agentic AI Overlay Working Group has been developing a vendor-independent reference architecture that defines how large enterprises can securely and effectively deploy agentic AI systems at scale. In this session, the Working Group will present its draft reference architecture to the ONUG community for open discussion and feedback.
The objective is to ensure that the framework reflects the requirements and priorities of the user community, providing clear guidance to vendors on what is needed for interoperable, non-proprietary Agentic AI infrastructures. Attendees will have the opportunity to shape the architecture by contributing their perspectives on network, security, and data overlays, as well as cross-enterprise use cases.
This is a working session designed to align the ONUG community around a shared, ecosystem-driven approach — one that ensures agentic AI systems can be trusted, scalable, and enterprise-ready.
