Internet-Draft PCEP MIB April 2014
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.
The PCE communication protocol (PCEP) is the communication protocol
between a PCC and PCE for point-to-point (P2P) path computations and
is defined in [RFC5440]. Such PCEP communication 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.
This memo defines a portion of the Management Information Base (MIB)
for use with network management protocols in the Internet community.
In particular, it defines a MIB module that can be used to monitor
PCEP communications between a PCC and a PCE, or between two PCEs.
This document uses the terminology defined in [RFC4655] and
[RFC5440].
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
RFC 3410 [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,
RFC 2578 [RFC2578], STD 58, RFC 2579 [RFC2579], and STD 58, RFC 2580
[RFC2580].
3. 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, RFC 2119
[RFC2119].

Internet-Draft PCEP MIB April 2014
4. PCEP MIB Module Architecture
The PCEP MIB contains the following information:
a. PCE and PCC entity status (see pcePcepEntityTable).
b. PCEP peer information (see pcePcepPeerTable).
c. PCEP session information (see pcePcepSessTable).
d. Notifications to indicate PCEP session changes.
4.1. pcePcepEntityTable
The pcePcepEntityTable contains one row for each PCEP-speaking entity
(PCC or PCE). Each row is read-only and contains current status
information plus the running configuration of the PCEP-speaking
entity.
4.2. pcePcepPeerTable
The pcePcepPeerTable contains one row for each PCEP peer that the
PCEP entity (PCE or PCC) knows about. Each row is read-only and
contains information to identify the peer, the running configuration
relating to that peer and statistics that track the messages
exchanged with that peer and its response times.
Since PCEP sessions can be ephemeral, the pcePcepPeerTable tracks a
peer even when no PCEP session currently exists to that peer. The
statistics contained in pcePcepPeerTable are an aggregate of the
statistics for all successive sessions to that peer.
To limit the quantity of information that is stored, an
implementation MAY choose to discard a row from the pcePcepPeerTable
if and only if no PCEP session exists to the corresponding peer.
4.3. pcePcepSessTable
The pcePcepSessTable contains one row for each PCEP session that the
PCEP entity (PCE or PCC) is currently participating in. Each row is
read-only and contains the running configuration that is applied to
the session, plus identifiers and statistics for the session.
The statistics in pcePcepSessTable are semantically different from
those in pcePcepPeerTable since the former apply to the current
session only, whereas the latter are the aggregate for all sessions
that have existed to that peer.
Koushik, et al. Expires October 4, 2014 [Page 4]
Internet-Draft PCEP MIB April 2014
Although [RFC5440] forbids there from being more than one active PCEP
session between a given pair of PCEP entities at any one time, there
is a window during session establishment where the pcePcepSessTable
may contain two rows for a given peer, one representing a session
initiated by the local PCEP speaker and one representing a session
initiated by the remote PCEP speaker. If either of these sessions
reaches active state, then the other is discarded.
4.4. PCEP Notifications
The PCEP MIB contains notifications for the following conditions.
a. pcePcepSessUp: PCEP Session has gone up.
b. pcePcepSessDown: PCEP Session has gone down.
c. pcePcepSessLocalOverload: Local PCEP entity has sent an overload
PCNtf on this session.
d. pcePcepSessLocalOverloadClear: Local PCEP entity has sent an
overload-cleared PCNtf on this session.
e. pcePcepSessPeerOverload: Remote PCEP entity has sent an overload
PCNtf on this session.
f. pcePcepSessPeerOverloadClear: Remote PCEP entity has sent an
overload-cleared PCNtf on this session.
4.5. Relationship to other MIB modules
The PCEP MIB imports the following textual conventions from the INET-
ADDRESS-MIB defined in RFC 4001 [RFC4001]:
o InetAddressType
o InetAddress
PCEP relies on existing protocols which have specialized MIB objects
to monitor their own activities. Consequently this document
considers that the monitoring of underlying protocols is out of scope
of the PCEP MIB module.

6. Security Considerations
The readable objects in the PCE-PCEP-MIB module (i.e., those with
MAX-ACCESS other than not-accessible) may be considered sensitive in
some environments since, collectively, they provide information about
the amount and frequency of path computation requests and responses
within the network and can reveal some aspects of their
configuration.
In such environments it is important to control also GET and NOTIFY
access to these objects and possibly even to encrypt their values
when sending them over the network via SNMP.
SNMP versions prior to SNMPv3 did not include adequate security.
Even if the network itself is secure (for example by using IPsec),
even then, there is no control as to who on the secure network is
allowed to access and GET/SET (read/change/create/delete) the objects
in this MIB module.
It is RECOMMENDED that implementers consider the security features as
provided by the SNMPv3 framework (see [RFC3410], section 8),
including full support for the SNMPv3 cryptographic mechanisms (for
authentication and privacy).
Further, deployment of SNMP versions prior to SNMPv3 is NOT
RECOMMENDED. Instead, it is RECOMMENDED to deploy SNMPv3 and to
enable cryptographic security. It is then a customer/operator
responsibility to ensure that the SNMP entity giving access to an
instance of this MIB module is properly configured to give access to
the objects only to those principals (users) that have legitimate
rights to indeed GET or SET (change/create/delete) them.
7. IANA Considerations
The MIB module in this document uses the following IANA-assigned
OBJECT IDENTIFIER values recorded in the SMI Numbers registry:
Descriptor OBJECT IDENTIFIER value
---------- -----------------------
pcePcepMIB { mib-2 XXX }
Editor's Note (to be removed prior to publication): the IANA is
requested to assign a value for "XXX" under the 'mib-2' subtree and
to record the assignment in the SMI Numbers registry. When the
assignment has been made, the RFC Editor is asked to replace "XXX"
(here and in the MIB module) with the assigned value and to remove
this note.
