A Network YANG Data Model for Attachment Circuits
RFC 9835, “A Network YANG Data Model for Attachment Circuits”, 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
This document specifies a network model for attachment circuits. The model can be used for the provisioning of attachment circuits prior or during service provisioning (e.g., VPN, Network Slice Service). A companion service model is specified in the YANG Data Models for Bearers and 'Attachment Circuits'-as-a-Service (ACaaS) (I-D.ietf- opsawg-teas-attachment-circuit).
The module augments the base network ('ietf-network') and the Service Attachment Point (SAP) models with the detailed information for the provisioning of attachment circuits in Provider Edges (PEs).
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.
