IP Performance Metrics (IPPM) Metrics Registry
Status of this Memo
This document specifies an Internet Best Current Practices for the
Internet Community, and requests discussion and suggestions for
improvements. Distribution of this memo is unlimited.

Abstract
This memo defines a registry for IP Performance Metrics (IPPM). It
assigns and registers an initial set of OBJECT IDENTITIES to
currently defined metrics in the IETF.
This memo also defines the rules for adding IP Performance Metrics
that are defined in the future and for encouraging all IP performance
metrics to be registered here.
IANA has been assigned to administer this new registry.

RFC 4148 IP Performance Metrics Registry August 2005
1. 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].
2. Overview
This memo defines a registry of the current metrics and a framework
for the integration of future metrics for the following reasons:
o to permit metrics to be clearly referenced by MIB modules or other
data models;
o to provide metrics identifiers for measurement interoperability;
o to take special care with the integration of future standardized
metrics because it is a continuous process;
o to provide room where other standards bodies can register their
metrics in order to encourage IP performance metrics to have
OBJECT IDENTITIES rooted at a common point because the intent of
the IPPM WG is to cooperate with other appropriate standards
bodies (or fora) to promote consistent metrics;
o and, similarly, to provide room for enterprises to register
metrics.
3. IP Performance Metrics Registry Framework
MIB modules need to be able to reference IPPM Metrics precisely. The
registry associates an OBJECT-IDENTITY with each metric. For
example, Type-P-One-way-Delay and Type-P-One-way-Delay-Poisson-Stream
have different OBJECT IDENTITIES.
The registry has one branch. Metrics are identified in the
'ianaIppmMetrics' subtree.
Stephan Best Current Practice [Page 2]
RFC 4148 IP Performance Metrics Registry August 2005
This document defines an initial registry of the existing metrics
defined in the IPPM WG and the rules to manage the registry.
Documents defining metrics in the future will include in the IANA
section the registration information to identify these metrics
unambiguously.
4. Initial IPPM Metrics Registry Creation
The initial registry identifies the metrics currently defined in the
RFCs produced in the IPPM WG. To date, the IPPM WG defined 33
metrics related to the following 7 topics:
1. IPPM Metrics for Measuring Connectivity, RFC 2678 [RFC2678]
2. One-way Delay Metrics, RFC 2679 [RFC2679]
3. One-way Packet Loss Metrics, RFC 2680 [RFC2680]
4. Round-trip Delay Metrics, RFC 2681 [RFC2681]
5. One-way Loss Pattern Sample Metrics, RFC 3357 [RFC3357]
6. IP Packet Delay Variation Metric, RFC 3393 [RFC3393]
7. IPPM Metrics for periodic streams, RFC 3432 [RFC3432]
These are sequentially registered in the node ianaIppmMetrics.
The naming conventions used for the existing metrics, and encouraged
for new IPPM metrics, are:
o Metrics names conform SMIv2 rules for descriptors defined in
section 3.1 of [RFC2578];
o The name starts with the prefix 'ietf';
o 'Type-P' prefix is removed;
o '-' are removed;
o The letter following a '-' is changed to uppercase.

RFC 4148 IP Performance Metrics Registry August 2005
5. IANA Considerations
This section describes the rules for the management of the registry
by IANA.
5.1. Management Rules
Registrations are done sequentially by IANA in the ianaIppmMetrics
subtree on the basis of 'Specification Required', as defined in
[RFC2434].
The reference of the specification must point to a stable document
including a title, a revision, and a date.
The name always starts with the name of the organization and must
respect the SMIv2 rules for descriptors defined in section 3.1 of
[RFC2578].
A document that creates new metrics would have an "IANA
Considerations" section in which it would describe new metrics to be
registered.
An OBJECT IDENTITY assigned to a metric is definitive and cannot be
reused. If a new version of a metric is produced, then it is
assigned with a new name and a new identifier.
5.2. Registration Template
The following is a proposed template to insert in the IANA
considerations section. For each metric, that section would
instantiate the following statement:
IANA has registed the following metric in the IANA-IPPM-METRICS-
REGISTRY-MIB:
aNewMetricName OBJECT-IDENTITY
STATUS current
DESCRIPTION
"The identifier for a new metric."

7. Security Considerations
This module does not define any management objects. Instead, it
assigns a set of OBJECT-IDENTITIES which may be used by other MIB
modules to identify specific IP Performance Metrics.
Meaningful security considerations can only be written in the MIB
modules that define management objects. This document has therefore
no impact on the security of the Internet.
