A Network YANG Data Model for Attachment Circuits
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., Network Slice Service). The companion service model is specified in [I-D.boro-opsawg-teas-attachment-circuit].¶
The module augments the SAP model with the detailed information for the provisioning of attachment circuits in Provider Edges (PEs).¶

1. Introduction
The procedure to provision a service in a service provider network may depend on the practices adopted by a service provider, including the flow put in place for the provisioning of advanced network services and how they are bound to an attachment circuit. For example, the same attachment circuit may be used to host multiple services. In order to avoid service interference and redundant information in various locations, a service provider may expose an interface to manage ACs network-wide. Customers can then request a base attachment circuit to be put in place, and then refer to that base AC when requesting services that are bound to that AC. [I-D.boro-opsawg-teas-attachment-circuit] specifies a data model for managing ACs as a service.¶
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., Network Slice Service).¶
The document leverages [RFC9182] and [RFC9291] by adopting an AC provisioning structure that uses data nodes that are defined in these RFCs. Some refinements were introduced to cover, not only conventional service provider networks, but also specifics of other target deployments (cloud, for example).¶
The AC network model is designed as an augmnetation to the Service Attachment Points (SAPs) model [I-D.ietf-opsawg-sap]. An AC can be bound to a single or multiple SAPs. Likewise, the model is designed to accomdate deployments where a SAP can be bound to one or multiple ACs.¶
The YANG data models in this document conform to the Network Management Datastore Architecture (NMDA) defined in [RFC8342].¶
2. Conventions and Definitions
The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "NOT RECOMMENDED", "MAY", and "OPTIONAL" in this document are to be interpreted as described in BCP 14 [RFC2119] [RFC8174] when, and only when, they appear in all capitals, as shown here.¶
The reader should be familiar with the terms defined in Section 2 of [I-D.ietf-opsawg-sap].¶
This document uses the term "network model" as defined in Section 2.1 of [RFC8969].¶
The meanings of the symbols in the YANG tree diagrams are defined in [RFC8340].¶
This document uses the following terms:¶
- Network controller:
-
Denotes a functional entity responsible for the management of the service provider network.¶
- Service orchestrator:
-
Refers to a functional entity that interacts with the customer of a network service. The service orchestrator is typically responsible for the attachment circuits, the Provider Edge (PE) selection, and requesting the activation of the requested service to a network controller.¶
- Service provider network:
-
A network that is able to provide network services (e.g., Network Slice Services).¶
- Service provider:
-
A service provider that offers network services (e.g., Network Slice Services).¶

4. Description of the Attachment Circuit YANG Module
4.1. Overall Structure of the Module
The overall tree structure of the module is shown in Figure 2. A node can host one or more SAPs as per [I-D.ietf-opsawg-sap]. Each SAP terminate one or multiple ACs. The SAP model in [I-D.ietf-opsawg-sap] is thus augmented with required AC-related information. Also, in order to ease the correlation between the AC exposed at the service layer and the one that is actually provisioned in the network operation, a reference to the AC exposed to the customer ('ac-ref') is stored in the 'ac-ntw' module.¶
Unlike the AC service model, an AC is uniquely identified within the scope of a node not a network. An AC can be characterized using Layer 2 connectivity, Layer 3 connectivity, routing protocols, OAM, and security considerations. In order to factorize a set of data that is provisioned for a set of ACs, a set of profiled can be defined at the network level, and then called under the node level. The information contained in the profile are thus inherited, unless the corresponding data node is refined at the AC level. In such as case, the value provided at the AC level takes precedence over the global one.¶

6. Security Considerations
The YANG module specified in this document defines a schema for data that is designed to be accessed via network management protocols such as NETCONF [RFC6241] or RESTCONF [RFC8040]. The lowest NETCONF layer is the secure transport layer, and the mandatory-to-implement secure transport is Secure Shell (SSH) [RFC6242]. The lowest RESTCONF layer is HTTPS, and the mandatory-to-implement secure transport is TLS [RFC8446].¶
The Network Configuration Access Control Model (NACM) [RFC8341] provides the means to restrict access for particular NETCONF or RESTCONF users to a preconfigured subset of all available NETCONF or RESTCONF protocol operations and content.¶
There are a number of data nodes defined in this YANG module that are writable/creatable/deletable (i.e., config true, which is the default). These data nodes may be considered sensitive or vulnerable in some network environments. Write operations (e.g., edit-config) and delete operations to these data nodes without proper protection or authentication can have a negative effect on network operations. These are the subtrees and data nodes and their sensitivity/ vulnerability in the "ietf-ac-ntw" module:¶
Some of the readable data nodes in this YANG module may be considered sensitive or vulnerable in some network environments. It is thus important to control read access (e.g., via get, get-config, or notification) to these data nodes. These are the subtrees and data nodes and their sensitivity/vulnerability in the "ietf-ac-svc" module:¶
7. IANA Considerations
IANA is requested to register the following URI in the "ns" subregistry within the "IETF XML Registry" [RFC3688]:¶
URI: urn:ietf:params:xml:ns:yang:ietf-ac-ntw Registrant Contact: The IESG. XML: N/A; the requested URI is an XML namespace.¶
IANA is requested to register the following YANG module in the "YANG Module Names" subregistry [RFC6020] within the "YANG Parameters" registry.¶
Name: ietf-ac-ntw Maintained by IANA? N Namespace: urn:ietf:params:xml:ns:yang:ietf-ac-ntw Prefix: ac Reference: RFC xxxx¶
