Introduction YANG [RFC6020] and [RFC7950] is a data modeling language that was introduced to define the contents of a conceptual data store that allows networked devices to be managed using NETCONF [RFC6241]. YANG has proved relevant beyond its initial confines, as bindings to other interfaces (e.g. RESTCONF [RFC8040]) and encoding other than XML Saad, et al. Expires August 19, 2019 [Page 2] Internet-Draft TE YANG Data Model February 2019 (e.g. JSON) are being defined. Furthermore, YANG data models can be used as the basis of implementation for other interfaces, such as CLI and programmatic APIs. This document describes YANG data model for TE Tunnels, Label Switched Paths (LSPs) and TE interfaces and covers data applicable to generic or device-independent, device-specific, and Multiprotocol Label Switching (MPLS) technology specific. The document describes a high-level relationship between the modules defined in this document, as well as other external protocol YANG modules. The TE generic YANG data model does not include any data specific to a signaling protocol. It is expected other data plane technology model(s) will augment the TE generic YANG data model. Also, it is expected other YANG module(s) that model TE signaling protocols, such as RSVP-TE ([RFC3209], [RFC3473]), or Segment-Routing TE (SR-TE) will augment the TE generic YANG module. 1.1. Terminology 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 terminology for describing YANG data models is found in [RFC7950]. 1.2. Prefixes in Data Node Names In this document, names of data nodes and other data model objects are prefixed using the standard prefix associated with the corresponding YANG imported modules, as shown in Table 1.

TE Technology Models This document describes the TE generic YANG data model that is independent of any dataplane technology. One of the design objectives is to allow specific data plane technology models to reuse the TE generic data model and possibly augment it with technology specific data. The elements of the TE generic YANG data model, including TE tunnels, LSPs, and interfaces have leaf(s) that identify the technology layer where they reside. For example, the LSP encoding type can identify the technology associated with a TE tunnel or LSP. Also, the TE generic YANG data model does not cover signaling protocol data. This is expected to be covered by augmentations defined in other document(s). 1.4. State Data Organization The Network Management Datastore Architecture (NMDA) [RFC8342] addresses modeling state data for ephemeral objects. This draft adopts the NMDA proposal for configuration and state data representation as per IETF guidelines for new IETF YANG models. 2. Model Overview The data model(s) defined in this document cover core TE features that are commonly supported across different vendor implementations. The support of extended or vendor specific TE feature(s) is expected to be in augmentations to the base model defined in this document. Saad, et al. Expires August 19, 2019 [Page 4] Internet-Draft TE YANG Data Model February 2019 2.1. Module(s) Relationship The TE generic YANG data model defined in "ietf-te.yang" covers the building blocks that are device independent and agnostic of any specific technology or control plane instances. The TE device model defined in "ietf-te-device.yang" augments the TE generic YANG data model and covers data that is specific to a device - for example, attributes of TE interfaces, or TE timers that are local to a TE node. The TE data model for specific instances of data plane technology exist in a separate YANG module(s) that augment the TE generic YANG data model. For example, the MPLS-TE module "ietf-te-mpls.yang" is defined in another document and augments the TE generic model as shown in Figure 1. The TE data model for specific instances of signaling protocol are outside the scope of this document and are defined in other documents. For example, the RSVP-TE YANG model augmentation of the TE model is covered in [I-D.ietf-teas-yang-rsvp]. Saad, et al.

Expires August 19, 2019 [Page 6] Internet-Draft TE YANG Data Model February 2019 2.2. Design Considerations The following design considerations are taken into account with respect data organization: o reusable TE data types that are data plane independent are grouped in the TE generic types module "ietf-te-types.yang" defined in [I-D.ietf-teas-yang-te-types] o reusable TE data types that are data plane specific are defined in a data plane type module, e.g. "ietf-te-packet-types.yang" as defined in [I-D.ietf-teas-yang-te-types]. Other data plane types are expected to be defined in separate module(s) as shown in Figure 2 o The TE generic YANG data model "ietf-te" contains device independent data and can be used to model data off a device (e.g. on a controller). The device-specific TE data is defined in module "ietf-te-device" as shown in Figure 1. o In general, minimal elements in the model are designated as "mandatory" to allow freedom to vendors to adapt the data model to their specific product implementation. o This model declares a number of TE functions as features that can be optionally supported. 2.3.

Expires August 19, 2019 [Page 45] Internet-Draft TE YANG Data Model February 2019 Figure 3: TE generic model configuration and state tree 3. Model Organization The TE generic YANG data module "ietf-te" covers configuration, state, RPC and notifications data pertaining to TE global, tunnels and LSPs parameters that are device independent. The container "te" is the top level container in the data model. The presence of this container enables TE function system wide. The model top level organization is shown below in Figure 4: module: ietf-te +--rw te! +--rw globals . . +--rw tunnels . . +-- lsps-state rpcs: +---x globals-rpc +---x tunnels-rpc notifications: +---n globals-notif +---n tunnels-notif Figure 4: TE generic highlevel model view 3.1. Global Configuration and State Data The global TE branch of the data model covers configurations that control TE features behavior system-wide, and its respective state. Examples of such configuration data are: o Table of named SRLG mappings o Table of named (extended) administrative groups mappings o Table of named path-constraints sets o System-wide capabilities for LSP reoptimization Saad, et al. Expires August 19, 2019 [Page 46] Internet-Draft TE YANG Data Model February 2019 * Reoptimization timers (periodic interval, LSP installation and cleanup) * Link state flooding thresholds * Periodic flooding interval o Global capabilities that affect originating, transiting and terminating LSPs. For example: * Path selection parameters (e.g. metric to optimize, etc.) * Path or segment protection parameters 3.2. Interfaces Configuration and State Data This branch of the model covers configuration and state data corresponding to TE interfaces that are present on a device. The module "ietf-te-device" is introduced to hold such TE device specific properties. Examples of TE interface properties are: * Maximum reservable bandwidth, bandwidth constraints (BC) * Flooding parameters * Flooding intervals and threshold values * interface attributes * (Extended) administrative groups * SRLG values * TE metric value * Fast reroute backup tunnel properties (such as static, auto-tunnel) module: ietf-te-device augment /te:te: +--rw interfaces . +-- rw te-dev:te-attributes <> . +-- ro state <> Figure 5: TE interface state The derived state associated with interfaces is grouped under the interface "state" sub-container as shown in Figure 5. This covers state data such as: o Bandwidth information: maximum bandwidth, available bandwidth at different priorities and for each class-type (CT) o List of admitted LSPs Saad, et al. Expires August 19, 2019 [Page 47] Internet-Draft TE YANG Data Model February 2019 * Name, bandwidth value and pool, time, priority o Statistics: state counters, flooding counters, admission counters (accepted/rejected), preemption counters o Adjacency information * Neighbor address * Metric value 3.3. Tunnels Configuration and State Data This branch covers data related to TE tunnels configuration and state. The derived state associated with tunnels is grouped under a state container as shown in Figure 6. module: ietf-te +--rw te! +--rw tunnels <> . +-- ro state <> Figure 6: TE interface state tree Examples of tunnel configuration data for TE tunnels: o Name and type (e.g. P2P, P2MP) of the TE tunnel o Administrative and operational state of the TE tunnel o Set of primary and corresponding secondary paths and corresponding path attributes o Bidirectional path attribute(s) including forwarding and reverse path properties o Protection and restoration path parameters 3.3.1. Tunnel Compute-Only Mode A configured TE tunnel, by default, is provisioned so it can carry traffic as soon as a valid path is computed and an LSP instantiated. In some cases, however, a TE tunnel may be provisioned for the only purpose of computing a path and reporting it without the need to instantiate the LSP or commit any resources. In such a case, the Saad, et al. Expires August 19, 2019 [Page 48] Internet-Draft TE YANG Data Model February 2019 tunnel is configured in "compute-only" mode to distinguish it from default tunnel behavior. A "compute-only" TE tunnel is configured as a usual TE tunnel with associated per path constraint(s) and properties on a device or controller. The device or controller computes the feasible path(s) subject to configured constraints and reflects the computed path(s) in the LSP(s) Record-Route Object (RRO) list. At any time, a client may query "on-demand" the "compute-only" TE tunnel computed path(s) properties by querying the state of the tunnel. Alternatively, the client can subscribe on the "compute-only" TE tunnel to be notified of computed path(s) and whenever it changes. 3.3.2. Tunnel Hierarchical Link Endpoint TE LSPs can be set up in MPLS or Generalized MPLS (GMPLS) networks to be used to form links to carry traffic in in other (client) networks [RFC6107]. In this case, the model introduces the TE tunnel hierarchical link endpoint parameters to identify the specific link in the client layer that the underlying TE tunnel is associated with. 3.4. TE LSPs State Data TE LSPs are derived state data that are present whenever the LSP(s) are instantiated - for example, when associated signaling completes. TE LSPs exists on routers as ingress (starting point of LSP), transit (mid-point of LSP ), or egress (termination point of the LSP). In the model, the nodes holding TE LSP data exist in the read-only lsps- state list as show in Figure 3. 3.5. Global RPC Data This branch of the model covers system-wide RPC execution data to trigger actions and optionally expect responses. Examples of such TE commands are to: o Clear global TE statistics of various features 3.6. Interface RPC Data This collection of data in the model defines TE interface RPC execution commands. Examples of these are to: o Clear TE statistics for all or for individual TE interfaces o Trigger immediate flooding for one or all TE interfaces Saad, et al. Expires August 19, 2019 [Page 49] Internet-Draft TE YANG Data Model February 2019 3.7. Tunnel RPC Data This branch of the model covers TE tunnel RPC execution data to trigger actions and expect responses. The TE generic YANG data model defines target containers that an external module in [I-D.ietf-teas-yang-path-computation] augments with RPCs that allow the invocation of certain TE functions (e.g. path computations). 4.

IANA Considerations This document registers the following URIs in the IETF XML registry [RFC3688]. Following the format in [RFC3688], the following registrations are requested to be made. URI: urn:ietf:params:xml:ns:yang:ietf-te XML: N/A, the requested URI is an XML namespace. URI: urn:ietf:params:xml:ns:yang:ietf-te-device XML: N/A, the requested URI is an XML namespace. This document registers two YANG modules in the YANG Module Names registry [RFC6020]. name: ietf-te namespace: urn:ietf:params:xml:ns:yang:ietf-te prefix: ietf-te reference: RFCXXXX name: ietf-te-device namespace: urn:ietf:params:xml:ns:yang:ietf-te-device prefix: ietf-te-device reference: RFCXXXX 6. Security Considerations The YANG module defined in this memo is designed to be accessed via the NETCONF protocol [RFC6241]. The lowest NETCONF layer is the secure transport layer and the mandatory-to-implement secure transport is SSH [RFC6242]. The NETCONF access control model [RFC8341] provides means to restrict access for particular NETCONF Saad, et al. Expires August 19, 2019 [Page 94] Internet-Draft TE YANG Data Model February 2019 users to a pre-configured subset of all available NETCONF protocol operations and content. There are a number of data nodes defined in the YANG module which 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., ) to these data nodes without proper protection can have a negative effect on network operations. Following are the subtrees and data nodes and their sensitivity/vulnerability: "/te/globals": This module specifies the global TE configurations on a device. Unauthorized access to this container could cause the device to ignore packets it should receive and process. "/te/tunnels": This list specifies the configured TE tunnels on a device. Unauthorized access to this list could cause the device to ignore packets it should receive and process. "/te/lsps-state": This list specifies the state derived LSPs. Unauthorized access to this list could cause the device to ignore packets it should receive and process. "/te/interfaces": This list specifies the configured TE interfaces on a device. Unauthorized access to this list could cause the device to ignore packets it should receive and process. 7.
