Path Computation Element Protocol (PCEP) Management Information Base
draft-ietf-pce-pcep-mib-07
This memo defines a portion of the Management Information Base for use with network management protocols in the Internet community. In particular, it describes managed objects for modeling of Path Computation Element communication Protocol (PCEP) for communications between a Path Computation Client (PCC) and a Path Computation Element (PCE), or between two PCEs.

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.
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].
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].
The terminology used in this document is built on notions introduced and discussed in PCE WG documents. The reader should be familiar with these documents.
This document also uses the terminology defined in [RFC4655] and [RFC5440].
The PCEP MIB contains the following information:
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.
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.
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.
The PCEP MIB contains notifications for the following conditions.
The PCEP MIB imports the following textual conventions from the INET-ADDRESS-MIB defined in RFC 4001 [RFC4001]:
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.

Consider the case where a PCReq message is received by a PCE

"The notifications for a PCEP MIB implementation."
::= { pcePcepGroups 2 }
END
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.
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.
