A YANG Data Model for Segment Routing in IPv6 (SRv6) support in Path
Computation Element Communications Protocol (PCEP)
draft-li-pce-pcep-srv6-yang-02
Abstract
This document augments 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 in support for Segment Routing in
IPv6. The data model includes configuration data and state data
(status information and counters for the collection of statistics).

1. Introduction
The Path Computation Element (PCE) defined in [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.
PCEP is the communication protocol between a PCC and PCE and is
defined in [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). [RFC8231] specifies extensions to PCEP to
enable stateful control of MPLS TE LSPs.
[I-D.ietf-pce-segment-routing-ipv6] extends [RFC8664] to support SR
