IETFn
IETFn is a fictional protocol suite created for illustrative purposes in discussions about future networking architectures. In this article, IETFn stands for Integrated Edge and Transport Function Network.
IETFn is designed to emphasize function-centric addressing rather than device-centric addressing. It introduces Function IDs (FIDs)
The architecture envisions a federated registry of FIDs. Clients send requests with a FID and optional parameters;
Security constructs include token-based authentication and authorization, integrity protection with digital signatures, and privacy-preserving query mechanisms.
Origin and status: IETFn originated in theoretical discussions and pedagogical materials exploring prospective naming and discovery
Critics argue that function-centric models may complicate caching, security, and policy enforcement, while proponents cite improved
