Extensions to the Path Computation Element Protocol(PCEP) Management
Information Base(MIB) Module
draft-pce-mib-extensions-01
Abstract
This memo defines a portion of the Management Information Base (MIB)
for use with network management protocols in the Internet community.
In particular, it describes extensions to the managed objects for
modeling of the Path Computation Element Communication Protocol
(PCEP) for communications between a Path Computation Client (PCC) and
a Path Computation Element (PCE), or between two PCEs, that support
stateful capabilities.

1. Introduction
The 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 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).
[RFC7420] defined a MIB module that can be used to monitor PCEP
interactions between a PCC and a PCE, or between two PCEs. This memo
proposes extensions to the MIB module that can help monitor
interactions between PCEP peers that have stateful capabilities as
defined in [I-D.ietf-pce-stateful-pce],
[I-D.ietf-pce-pce-initiated-lsp] and
[I-D.ietf-pce-stateful-sync-optimizations].
The scope of this document is to extend the MIB module for the PCEP
base protocol as defined in [RFC7420].

1.1. Requirements Language
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 BCP 14 [RFC2119].
1.2. Terminology
This document uses the terminology defined in [RFC4655] and
[RFC5440], [draft-ietf-pce-stateful-pce-10], [draft-ietf-pce-pce-
initiated-lsp-03] and [draft-ietf-pce-stateful-sync-optimizations-
02]. In particular, it uses the following acronyms.
o Path Computation Request (PCReq) message.
o Path Computation Reply (PCRep) message.
o Notification (PCNtf) message.
o Error (PCErr) message.
o LSP State Report (PCRpt) message.
o LSP State Update (PCUpd) message.
o LSP Initiate (PCInitiate) message.
This document uses the term "PCEP entity" to refer to a local PCEP
speaker, "peer" to refer to a remote PCEP speaker, and "PCEP speaker"
where it is not necessary to distinguish between local and remote.
2. The Internet-Standard Management Framework
For a detailed overview of the documents that describe the current
Internet-Standard Management Framework, please refer to section 7 of
[RFC3410].
Managed objects are accessed via a virtual information store, termed
the Management Information Base or MIB. MIB objects are generally
accessed through the Simple Network Management Protocol (SNMP).
Objects in the MIB are defined using the mechanisms defined in the
Structure of Management Information (SMI). This memo specifies a MIB
module that is compliant to the SMIv2, which is described in STD 58,
[RFC2578], STD 58, [RFC2579] and STD 58, [RFC2580].

Internet-Draft Extenstions to PCEP MIB Module October 2016
3. Overview
The PCEP MIB module contains the following information:
a. PCE and PCC local entity status (see
pcePcepEntityTable [RFC7420])
b. PCEP peer information (see pcePcepPeerTable [RFC7420])
c. PCEP session information (see pcePcepSessTable [RFC7420])
d. Notifications to indicate PCEP session changes ([RFC7420])
This document proposes additional "read-only" access fields for the
tables pcePcepEntityTable, pcePcepPeerTable and pcePcepSessTable.
These new fields will be defined in new tables pcePcepXEntityTable,
pcePcepXPeerTable and pcePcepXSessTable that augment
pcePcepEntityTable, pcePcepPeerTable and
pcePcepSessTable respectively. No changes to, or additional,
Notifications are proposed.
These new objects help a user to get information on stateful timers
configured, stateful capabilities negotiated by the peers, as well as
statistics about different kinds of messages exchanged between PCEP
speakers.
3.1. pcePcepXEntityTable
The PCEP MIB module may contain status information for multiple
logical local PCEP entities. The pcePcepXEntityTable contains one
row for each local PCEP entity. It augments the table
pcePcepEntityTable, and is indexed by the object pcePcepEntityIndex
defined in pcePcepEntityTable.
This table includes the following information:
a. State timeout interval value configured.
b. Redelegation timeout interval value configured.
The state timeout and redelegation timeout intervals are defined in
[draft-ietf-pce-stateful-pce-10], and extended in [draft-ietf-pce-
pce-initiated-lsp-03].

Internet-Draft Extenstions to PCEP MIB Module October 2016
3.2. pcePcepXPeerTable
The pcePcepXPeerTable augments the pcePcepPeerTable which contains
one row for each peer that the local PCEP entity knows about. Each
row is read-only and contains information to identify the peer.
This table includes the following information for each peer:
a. Number of PCRpts sent/received.
b. Number of PCRpts sent/received with different flags on:
* Sync
* Delegate
* Create
* Remove
c. Number of PCUpds sent/received.
d. Number of PCupds sent/received with different flags on.
* Sync
* Delegate
e. Number of PCInitiates sent/received
f. Number of PCInitiates sent/received with different flags on.
* Create
* Remove
For PCUpds, the sync flag is used only in the case of PCE triggered
initial sync and PCE triggered resync as defined in [draft-ietf-pce-
stateful-sync-optimizations-02].
3.3. pcePcepXSessTable
The pcePcepXSessTable augments the pcePcepSessTable. The
pcePcepSessTable contains one row for each PCEP session that the PCEP
entity (PCE or PCC) is currently participating in.
The statistics in pcePcepSessTable are semantically different from
those in pcePcepPeerTable since the former applies to the current
Ramany, et al. Expires April 10, 2017 [Page 5]
Internet-Draft Extenstions to PCEP MIB Module October 2016
session only, whereas the latter is the aggregate for all sessions
that have existed to that peer.
The pcePcepXSessTable will include the same information as in
pcePcepXPeerTable, but for each session. Apart from those fields
described in 3.2, it has the following additional information.
a. Stateful capabilities negotiated on the session. This is the
intersection of the capabilities advertised by the local entity
and the remote peer.
