This document specifies a YANG service data model for Attachment Circuits (ACs). The model can be used for the provisioning of ACs prior or during service provisioning (e.g., Network Slice Service).¶
The model is designed with the intent to be reusable. Whether a service model reuses structures defined in the AC service model or simply include an AC reference is a design choice of these service models. Relying upon the AC model to manage ACs over which a service is delivered has the merit to decorrelate the management of a service vs. upgrade the AC components to reflect recent AC technologies or features.¶
Each AC is identified with a unique identifier within a domain. The mapping between this AC and a PE that terminates the AC is hidden to the application/customer that makes use of the AC service model. Such an information is internal to the network controller. Thus, the details about the (network node-specific) attachment interfaces are not exposed in this service model.¶

This document specifies a YANG service data model for managing attachment circuits (ACs) that are exposed by a network to its customers (e.g., an enterprise site, a network function, a hosting infrastructure, a peer network provider) . The model can be used for the provisioning of ACs prior or during advanced service provisioning (e.g., Network Slice Service).¶
Also, the model is designed with the intent to be reusable. Whether a service model reuses structures defined in the AC service model or simply includes an AC reference (that was communicated during AC instantiation) is a design choice of these service models. Relying upon the AC service model to manage ACs over which services are delivered has the merit to decorrelate the management of a service vs. upgrade the AC components to reflect recent AC technologies or new features (e.g., new encryption scheme, additional routing protocol).¶
Each AC is identified with a unique identifier within a domain. From a network provider standpoint, an AC can be bound to a single or multiple SAPs [I-D.ietf-opsawg-sap]. Likewise, a SAP can be bound to one or multiple ACs. However, the mapping between this AC and a local PE that terminates the AC is hidden to the application that makes use of the AC service model. This information is internal to the Network controller. As such, the details about the (node-specific) attachment interfaces are not exposed in this service model.¶
The YANG data model in this document conforms to the Network Management Datastore Architecture (NMDA) defined in [RFC8342].¶
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 meanings of the symbols in the YANG tree diagrams are defined in [RFC8340].¶
This document uses the following terms:¶
Denotes a functional entity responsible for the management of the service provider network.¶
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.¶
A network that is able to provide network services (e.g., Network Slice Services).¶
A service provider that offers network services (e.g., Network Slice Services).¶
Figure 1 depictes two target topology flavors that may host ACs. A CE may be a physical node or a logical entity. The same AC request may include one or multiple ACs that may belong to one or both of these flavors. For the sake of simplfying the illustration, only a subset of these ACs is shown in Figure 1.¶
CEs may be dedicated to one single service or host multiple services (e.g., service functions [RFC7665]). A single AC (as seen by a network provider) may be bound to one or multiple peer SAPs.¶
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 the 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.¶
Figure 2 shows the positioning of the AC service model is the overall service delivery process.¶

This section includes a non-exhaustive list of examples to illustrate the use of the AC service model.¶
An example of of a request message body to create a simple AC over an existing bearer is shown in Figure 3. The bearer reference is assumed to be known to both the customer and the network provider. How such reference is shared is out of scope.¶

}
An example of a request to create a simple AC, when the peer SAP is known, is shown in Figure 4. In this example, the peer SAP identifier points to an identifier of a service function. The (topological) location of that service function is assumed to be known to the network controller. For example, this can be determined as part of an on-demand procedure to instantiate a service function in a cloud. That instantiated service function can be granted a connectivity service via the provider network.¶

A customer may request adding a new AC by simply referring to an existing per-node AC profile as shown in Figure 8. This AC inherites all the data that was enclosed in the indicated per-node AC profile (IP addressing, routing, etc.).¶

The overall tree structure of the AC service module is shown in Figure 11.¶

The full tree structure is provided in Appendix A.¶
Each AC is identified with a unique identifier within a domain. The mapping between this AC and a local PE that terminates the AC is hidden to the application that makes use of the AC service model. This information is internal to the Network controller. As such, the details about the (node-specific) attachment interfaces are not exposed in this service model.¶
The 'specific-provisioning-profiles' container (Figure 12) can be used by a service provider to maintain a set of specific profiles that are similar to those defined in [RFC9181]. The exact definition of the profiles is local to each service provider. The model only includes an identifier for these profiles in order to facilitate identifying and binding local policies when building an AC.¶

As shown in Figure 12, two profile types can be defined: 'specific-provisioning-profiles' and 'service-provisioning-profiles'. Whether only specific profiles, service profiles, or a combination thereff are used is local to each service provider.¶
The following specific rovisioning profiles can be defined:¶
Refers to a profile that defines the external connectivity provided to a site that is connected via an AC. External connectivity may be access to the Internet or restricted connectivity, such as access to a public/private cloud.¶
Refers to a set of policies related to the encryption setup that can be applied when provisioning an AC.¶
Refers to a set of policies, such as classification, marking, and actions (e.g., [RFC3644]).¶
Refers to a set of Bidirectional Forwarding Detection (BFD) policies [RFC5880] that can be invoked when building an AC.¶
Refers to the policies that apply to the forwarding of packets conveyed within an AC. Such policies may consist, for example, of applying Access Control Lists (ACLs).¶
Refers to a set of routing policies that will be invoked (e.g., BGP policies) when building an AC.¶
All these profiles are uniquely identified by the NETCONF/RESTCONF server by an identifier. To ease referencing these profiles by other data models, specific typedefs are defined for each of these profiles. Likewise, an attachment circuit referenc typedef is defiened when referencing a (global) attachment circuit by its name is required. These typedefs SHOULD be used when other modules need a reference to one of these profiles or attahment circuits.¶

As shown in the tree depicted in Figure 16, the 'routing-protocols' container defines th erequired parameters to enable the required routing features for an AC. One or more routing protocols can be associated with an AC. Such routing protocols are then enabled between a PE and the CE. Each routing instance is uniquely identified to accommodate scenarios where multiple instances of the same routing protocol have to be configured on the same link.¶
In addition to static routing, the module supports the following routing protocols:¶
The model also supports the Virtual Router Redundancy Protocol (VRRP) [RFC5798] on an AC.¶

For all supported routing protocols, 'address-family' indicates whether IPv4, IPv6, or both address families are to be activated. For example, this parameter is used to determine whether RIPv2 [RFC2453], RIP Next Generation (RIPng), or both are to be enabled [RFC2080].¶
As shown in the tree depicted in Figure 17, the 'oam' container defines OAM-related parameters of an AC.¶

<CODE ENDS>¶
The YANG module specified in this document define 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-svc" 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:¶
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-svc 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.¶
