YANG Data Models for Bearers and Attachment Circuits as a Service
RFC 9834, “YANG Data Models for Bearers and Attachment Circuits as a Service”, is a Proposed Standard document published in September 2025 by M. Boucadair, R. Roberts, O. Gonzalez de Dios, S. Barguil, B. Wu. The canonical text is published by the RFC Editor.
Abstract
Delivery of network services assumes that appropriate setup is provisioned over the links that connect customer termination points and a provider network. The required setup to allow successful data exchange over these links is referred to as an attachment circuit (AC), while the underlying link is referred to as a "bearer".
This document specifies a YANG service data model for ACs. This model can be used for the provisioning of ACs before or during service provisioning (e.g., RFC 9543 Network Slice Service).
The document also specifies a YANG service data model for managing bearers over which ACs are established.
What “Proposed Standard” means
An entry-level standards-track specification: stable, peer-reviewed and a solid basis for implementation, though it may still evolve before becoming an Internet Standard.
