Retrieval Methods YANG Data Model for Connectionless Operations, Administration, and Maintenance(OAM) protocols
draft-ietf-lime-yang-connectionless-oam-methods-00
This document presents a retrieval method YANG Data model for connectionless OAM protocols. It provides a technology-independent RPC commands for connectionless OAM protocols. The retrieval methods model presented here can be extended to include technology specific details. This is leading to uniformity between OAM protocols and support nested OAM workflows (i.e., performing OAM functions at different or same levels through a unified interface).
This Internet-Draft is submitted in full conformance with the provisions of BCP 78 and BCP 79.

Operations, Administration, and Maintenance (OAM) are important networking functions that allow operators to:
An overview of OAM tools is presented at [RFC7276].
Ping and Traceroute [RFC792], [RFC4443] are well-known fault verification and isolation tools, respectively, for IP networks. Over the years, different technologies have developed similar tools for similar purposes.
In this document, we present a retrieval method YANG Data model for connectionless OAM protocols. This module provides technology-independent RPC commands for connectionless OAM protocols. It is separated from the generic YANG model for connectionless OAM [lime base model]and can avoid mixing the models for the retrieved-data from the retrieval procedures. It is expected that retrieval procedures would evolve faster than the data model[lime base model] and will allow new procedures to be defined for retrieval of the same data defined by the base data model.
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 terms are defined in [RFC6241] and are not redefined here:
The following terms are defined in [RFC6020] and are not redefined here:
The terminology for describing YANG data models is found in [RFC6020].
TP - Test Point
MAC - Media Access Control
RPC - A Remote Procedure Call, as used within the NETCONF protocol
A simplified graphical representation of the data model is used in this document. The meaning of the symbols in these diagrams is as follows:
<status> <flags> <name> <opts> <type>
<status> is one of:
+ for current
x for deprecated
o for obsolete
<flags> is one of:
rw for configuration data
ro for non-configuration data
-x for rpcs
-n for notifications
<name> is the name of the node
Each node is printed as:
<opts> is one of:
? for an optional leaf or choice
! for a presence container
* for a leaf-list or list
[<keys>] for a list's keys
<type> is the name of the type for leafs and leaf-lists
If the node is augmented into the tree from another module, its name is printed as <prefix>:<name>.
In this document, we present a retrieval method YANG Data model for connectionless OAM protocols. This module provides technology-independent retrieval procedures (RPC commands) for connectionless OAM protocols. It will allow the user to flexibility to retrieve the retrieved-data which defined by the base data model[lime base model].
The rpc model facilitates issuing commands to a NETCONF server (in this case to the device that need to execute the OAM command) and obtaining a response.
Under connectionless-oam-methods module, we summarize the common OAM functions and define the generic rpc commands: continuity-check and path-discovery. In practice, these commands are supported by corresponding technology-specific OAM tools [RFC7276]. For example, for the IP OAM model, the continuity-check rpc corresponds to the IP Ping, while the path-discovery rpc command corresponds to IP Traceroute.
Note that the rpc command presented in this document is the base building block, which is used to derive a model for a technology-specific OAM(i.e., icmp ping, lsp ping), the base building block should be extended with corresponding technology specific parameters. To facilitate this and for future enhancements to data retrieval methods, the RPCs are captured under a separate module.
The generic path-discovery-data and continuity-check-data are used as data outputs from the different RPCs described in the document. Similar methods including other RPCs can retrieve the data using the same data model.
