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.

Internet-Draft                  PCEP MIB                       July 2014


   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", "NOT RECOMMENDED", "MAY" and
   "OPTIONAL" in this document are to be interpreted as described in BCP
   14, RFC 2119 [RFC2119].

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.



Koushik, et al.         Expires January 26, 2015                [Page 3]

Internet-Draft                  PCEP MIB                       July 2014


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.

   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.

Internet-Draft                  PCEP MIB                       July 2014


   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.
