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.

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:

   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]
