Network Working Group E. Stephan Request for Comments: 4148 France Telecom R&D BCP: 108 August 2005 Category: Best Current Practice 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. Copyright Notice Copyright (C) The Internet Society (2005). 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. Table of Contents 1. The Internet-Standard Management Framework ......................2 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]. 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]Show full document text
