This document specifies an Internet Best Current Practices for the
Internet Community, and requests discussion and suggestions for

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.

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:
