Dear all,

Strangely, the link appears broken.

Subject: [agent2agent] New I-D : A Dimensional Model for Characterizing AI Agent Protocol Proposals and Their Substrates

You don't often get email from parisa.foroughi=40nokia.com@dmarc.ietf.org. Learn why this is important<https://aka.ms/LearnAboutSenderIdentification>
Dear IETFers,
I have published a new I-D proposing a dimensional model for characterizing agentic protocols and their substrates:
https://datatracker.ietf.org/doc/draft-foroughi-agent-protocol-dimensions/<https://teams.microsoft.com/l/message/19:785e0265-8719-45ca-af5f-9b7c5d65ff37_94b45a06-ba3d-4443-b744-c7f238e91dc6@unq.gbl.spaces/1783546826122?context=%7B%22contextType%22%3A%22chat%22%7D>
The motivation is simple: help the community denoise the fast-growing agentic landscape and position concerns appropriately. Phrases like "we need a session protocol" or "we need cross-domain support" bundle several concerns across transport, identity, agent protocol, and orchestration layers. The conversation loses precision, and the technical work slowly derails. The draft is an analytical instrument that routes each concern to its proper layer — a dimensional choice at the agent protocol layer, a substrate-inherited property, or broader-scope work — so discussions become precise about where each concern actually lives.
I hope you find the model useful, and I would very much welcome feedback, especially on the dimensional value domains and on the comparison table, which is deliberately marked as a starting point. If any of this resonates and you would like to collaborate on sharpening it further, I would be glad to hear from you.
I will be attending the Vienna meeting — my first in person IETF meeting. Looking forward to discussions on the list or in Vienna.
Best regards,
Parisa
