The document specifies a common attachment circuits (ACs) YANG model, which is designed to be reusable by other models. This design is meant to ensure consistent AC structures among models that manipulate ACs. For example, this common model can be reused by service models to expose ACs as a service, service models that require binding a service to a set of ACs, network and device models to provision ACs, etc. |

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 "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., Network Slice Service). The document also specifies a YANG service model for managing bearers over which ACs are established. |
| | A Network YANG Data Model for Attachment Circuits |
| |
|
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). |

This document defines a YANG data model, referred to as the "AC Glue" model, to augment the Layer 2/3 Service Model (LxSM) and Layer 2/3 Network Model (LxNM) with references to attachment circuits (ACs). The AC Glue model enables a provider to associate Layer 2/3 VPN services (LxVPNs) with the underlying AC infrastructure, thereby facilitating consistent provisioning and management of new or existing ACs in conjunction with LxVPN services. Specifically, by introducing an integrated approach to AC and LxVPN management, this model supports Attachment Circuit-as-a-Service (ACaaS) and provides a standardized mechanism for aligning AC/VPN requests with the network configurations required to deliver them. |
