<abstract>
<t>This document defines a YANG data model for the management of
Path Computation Element communications Protocol (PCEP) for
communications between a Path Computation Client (PCC) and a Path
Computation Element (PCE), or between two PCEs. The data model
includes configuration data and state data (status information and
counters for the collection of statistics).</t>
</abstract>

<section title="Introduction" toc="default">
<t>The Path Computation Element (PCE) defined in <xref target="RFC4655"/>
is an entity that is capable of computing a network path or route
based on a network graph, and applying computational constraints.
A Path Computation Client (PCC) may make requests to a PCE for paths
to be computed.</t>
<t>PCEP is the communication protocol between a PCC and PCE and is
defined in <xref target="RFC5440"/>. PCEP interactions include path
computation requests and path computation replies as well as
notifications of specific states related to the use of a PCE in the
context of Multiprotocol Label Switching (MPLS) and Generalized MPLS
(GMPLS) Traffic Engineering (TE). <xref target='RFC8231'/>
specifies extensions to PCEP to enable stateful control of MPLS TE LSPs. </t>
<t>This document defines a YANG <xref target="RFC6020"/> data model
for the management of PCEP speakers. It is important to
establish a common data model for how PCEP speakers are identified,
configured, and monitored. The data model includes configuration data
and state data (status information and counters for the collection of
statistics).</t>
<t>This document contains a specification of the PCEP YANG module,
"ietf-pcep" which provides the PCEP <xref target="RFC5440"/> data
model.</t>
<t>The PCEP operational state is included in the same tree as the PCEP
configuration consistent with Network Management Datastore
Architecture <xref target="RFC8342"/>.
The origin of the data is indicated as per the origin metadata
annotation.</t>
</section>
<section title="Requirements Language" toc="default">
<t>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 <xref target="RFC2119" /> <xref target="RFC8174"/> when, and only when, they
appear in all capitals, as shown here.</t>

<!--
<list style="symbols">
<t>Brackets "[" and "]" enclose list keys.</t>
<t>Abbreviations before data node names: "rw" means
configuration (read-write) and "ro" state data

<section title="Objectives" toc="default">
<t>This section describes some of the design objectives for the model:
<list style="symbols">
<t>In case of existing implementations, it needs to map
the data model defined in this document to their proprietary
native data model. To facilitate such mappings, the data model
should be simple.</t>
<t>The data model should be suitable for new implementations to use
as is.</t>
<t>Mapping to the PCEP MIB Module should be clear.</t>
<t>The data model should allow for static configurations of peers.</t>
<t>The data model should include read-only counters in order to
gather statistics for sent and received PCEP messages,
received messages with errors, and messages that could not be sent
due to errors. This could be in a separate model which
augments the base data model.</t>
<t>It should be fairly straightforward to augment the base data model
for advanced PCE features.</t>
