YANG for Protocol for Forwarding Policy Configuration (FPC)
draft-ietf-dmm-fpc-yang-00

Abstract

This document provides YANG modules to exhibit a data model for the information models defining Forwarding Policy Configuration (FPC) to manage the separation of data-plane and control-plane. FPC defines a flexible mobility management system using FPC agent and FPC client functions. A FPC agent provides an abstract interface to the data-plane. The FPC client configures data-plane nodes by using the functions and abstractions provided by the FPC agent for the data-plane nodes.

Table of Contents

1. Introduction

This document provides YANG modules to exhibit a data model for the information models defining Forwarding Policy Configuration (FPC) [I-D.ietf-dmm-fpc-cpdp] to manage the separation of data-plane and control-plane. FPC defines a flexible mobility management system using FPC agent and FPC client functions. A FPC agent provides an abstract interface to the data-plane. The FPC client configures data-plane nodes by using the functions and abstractions provided by the FPC agent for the data-plane nodes.

2. Terminology

The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this document are to be interpreted as described in [RFC2119]. The following FPC-specific terms used in this document are defined in [I-D.ietf-dmm-fpc-cpdp].

3. YANG Data Model for the FPC protocol

This section provides a type mapping for FPC structures in YANG. When being mapped to a specific information such as YANG the data type MAY change.

Action and Descriptor Templates are mapped as choices. This was done to ensure no duplication of Types and avoid use of identityref for typing.

Policy Expressions are provided as default values. NOTE that a static value CANNOT be supported in YANG.

Mapping of templates to YANG are performed as follows:

The CONFIGURE and CONFIGURE-RESULT-NOTIFICATION use the yang-patch-status which is a container for edits. This was done to maximize YANG reuse.

In the configure rpc, operation-id is mapped to patch-id and in an edit the edit-type is mapped to operation.

The Result-Status attribute is mapped to the 'ok' (empty leaf) or errors structure.

The Policy-Status is mapped to entity-state to reduce YANG size.

Five modules are defined:

All modules defined in this specification make use of (import) ietf-inet-types as defined in [RFC6991].

ietf-dmm-fpc-settingsext and ietf-diam-trafficclassifier make use of (imports) ietf-yang-types as defined in [RFC6991].

ietf-dmm-fpc imports the restconf (ietf-restconf) [RFC8040] and yang patch (ietf-yang-patch) [RFC8072] modules.

ietf-pmip-qos and ietf-dmm-fpc-settings import the trafficselector from the ietf-traffic-selector-types module.

ietf-dmm-fpc-settings also imports the qosattribute (ietf-pmip-qos) and classifier (ietf-diam-trafficclassifier).

ietf-dmm-fpc-settingsext groups various settings, actions and descriptors and is used by the fpc module (ietf-dmm-fpc).

The following groupings are intended for reuse (import) by other modules.

The YANG modules in this document conform to the Network Management Datastore Architecture (NMDA) defined in [RFC8342].

A DPN conformant to NMDA MAY only have policies, installed policies, topology, domains and mobility session information that has been assigned to it in its intended and operational datastores.

ServiceGroups are not expected to appear in operational datastores of DPNs as they remain in and are used by FPC Agents and Clients. They MAY be operationally present in DNS when using the Dynamic Delegation and Discovery System (DDDS) as defined in [RFC3958] or the operational datastore of systems that provide equivalent functionality.

3.1. FPC YANG Model

This module defines the information model and protocol elements specified in this document.

This module references [RFC6991], [RFC8040] and the fpc-settingsext module defined in this document.
