1. Introduction
YANG [RFC6020] a data definition language that was introduced to
define the contents of a conceptual data store that allows networked
devices to be managed using NETCONF [RFC6241]. YANG is proving
relevant beyond its initial confines, as bindings to other

interfaces (e.g. ReST) and encoding other than XML (e.g. JSON) are
being defined. Furthermore, YANG data models can be used as the
basis of implementation for other interface, such as CLI and
programmatic APIs.
This document defines a YANG data model for representing and
manipulating TE Topologies. This model contains technology agnostic
TE Topology building blocks that can be augmented and used by other
technology-specific TE Topology models.
1.1. Tree Structure - Legend
A simplified graphical representation of the data model is presented
in Section 3 of this document. The following notations are used for
the YANG model data tree representation.
<status> <flags> <name> <opts> <type>
<status> is one of:
+ for current
x for deprecated
o for obsolete
<flags> is one of:
rw for read-write configuration data
ro for read-only non-configuration data
-x for execution rpcs
-n for notifications
<name> is the name of the node
If the node is augmented into the tree from another module, its
name is printed as <prefix>:<name>
<opts> is one of:
? for an optional leaf or node
! for a presence container
* for a leaf-list or list
Brackets [<keys>] for a list's keys
Curly braces {<condition>} for optional feature that make node
conditional
Colon : for marking case nodes
Ellipses ("...") subtree contents not shown
Parentheses enclose choice and case nodes, and case nodes are
also marked with a colon (":").
Beeram, et al Expires September 09, 2015 [Page 3]
Internet-Draft YANG - TE Topology March 2015
<type> is the name of the type for leafs and leaf-lists.
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.
+--------+-----------------+-----------+
| Prefix | YANG module | Reference |
+--------+-----------------+-----------+
| yang | ietf-yang-types | [RFC6991] |
| inet | ietf-inet-types | [RFC6991] |
+--------+-----------------+-----------+

2. Design Considerations
2.1. Extensible Model
The TE Topology model proposed in this document is meant to be
technology agnostic. Other technology specific TE Topology models
can augment and use the building blocks provided by the proposed
model.
2.2. Overlay/Underlay Relationship
The model captures overlay and underlay relationship for TE
nodes/links. For example - in networks where multiple TE Topologies
are built hierarchically, this model allows the user to start from a
specific topological element in the top most topology and traverse
all the way down to the supporting topological elements in the
bottom most topology.
2.3. Scheduling Parameters
The model allows time scheduling parameters to be specified for each
topological element. These parameters allow the provider to present
different topological views to the client at different time slots.

| +--rw schedule-duration? string
Beeram, et al Expires September 09, 2015 [Page 4]
Internet-Draft YANG - TE Topology March 2015
| +--rw repeat-interval? string
2.4. Provider vs Abstract TE Topologies
The TE Topology exported by the provider network to a client could
be a provider TE Topology or an abstract TE Topology. Provider TE
Topology is the TE topology exported by the provider network exactly
as the topology is known to the provider itself in an unmodified
way. The nodes/links that make up a provider TE topology are named
from the provider name space and are private to that topology.

+--rw provider
+--rw node* [te-node-id]
| +--rw te-node-id te-node-id
| :
+--rw link* [source-te-node-id source-te-link-id dest-te-node-id

+-rw source-te-node-id leafref
+--rw source-te-link-id leafref
+--rw dest-te-node-id leafref
+--rw dest-te-link-id leafref
:
An abstract TE Topology allows the provider to present the network
in abstract terms on per client basis. These topologies are
typically decoupled from the provider network topology. The
nodes/links that constitute an abstract TE Topology are picked from
a global pool of nodes/links. The nodes/links in the global pool can
be used in more than one abstract TE Topologies.

2.5. Open Items
- Relationship with "generic network topology" model: The generic
network topology building blocks are discussed in [YANG-NET-TOPO].
This version of the document does not use any of those building
blocks. The authors would like to explore the possibility of doing
that in future revisions of this document.
- Incremental notifications: The model proposed in this version does
not cover incremental notifications. The authors intend to add
this in future revisions of the document.
- Terminology: A provider network can export its TE Topology as is
to the client or it could export an abstract representation of
that TE Topology. This version of the document uses the term
"Provider TE Topology" for the former and the term "Abstract TE
Topology" for the latter. The authors would like to get wider
consensus on the use of these terms (and if necessary, find
alternatives) before the next revision.

"TE link is a logical construct that represents a way to
group/map information about certain physical resources
(and their properties) that interconnect TE nodes.
A Network Link connects a by Local (Source) node and
a Remote (Destination) Network Nodes via a set of the
nodes' TE links.
As it is possible to have several links between the same
source and destination nodes, and as a link could
potentially be re-homed, to
ensure that we would always know to distinguish between
links, every link is identified by a dedicated link
identifier.
Note that a link models a point-to-point link, not a
multipoint link.";

5. Security Considerations
The transport protocol used for retrieving/manipulating the TE
topology data MUST support authentication and SHOULD support
encryption. The data-model by itself does not create any security
implications.
6. IANA Considerations
This document registers the following URIs in the IETF XML registry
[RFC3688]. Following the format in [RFC3688], the following
registration is requested to be made.
URI: urn:ietf:params:xml:ns:yang:ietf-te-topology
XML: N/A, the requested URI is an XML namespace.
This document registers a YANG module in the YANG Module Names
registry [RFC6020].
