Network Working Group R. Dietz Request for Comments: 4150 Hifn, Inc. Category: Standards Track R. Cole JHU/APL August 2005 Transport Performance Metrics MIB Status of This Memo This document specifies an Internet standards track protocol for the Internet community, and requests discussion and suggestions for improvements. Please refer to the current edition of the "Internet Official Protocol Standards" (STD 1) for the standardization state and status of this protocol. Distribution of this memo is unlimited. Copyright Notice Copyright (C) The Internet Society (2005). Abstract This memo defines a portion of the Management Information Base (MIB) for use with network management protocols in the Internet community. In particular, it describes managed objects used for monitoring selectable performance metrics and statistics derived from the monitoring of network packets and sub-application level transactions. The metrics can be defined through reference to existing IETF, ITU, and other standards organizations' documents. The monitoring covers both passive and active traffic generation sources.

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 document continues the architecture created in the RMON2-MIB [RFC2021] by providing a major feature upgrade, primarily by providing new metrics and studies to assist in the analysis of performance for sub-application transaction flows in the network, in direct relationship to the transport of application layer protocols. Performance-monitoring agents have been widely used to analyze the parameters and metrics related to the perceived performance of distributed applications and services in networks. The metrics collected by these agents have ranged from basic response time to a Dietz & Cole Standards Track [Page 2] RFC 4150 TPM-MIB August 2005 combination of metrics related to the loss and re-transmission of datagrams and PDUs. Although the metrics are becoming more useful in the implementation of service-level monitoring and troubleshooting tools, the lack of a standard method to report these has limited the deployment to very specific customer needs and areas. This document is intended to create a general framework for the collection and reporting of performance-related metrics on sub- application level transaction flows in a network. The MIB in this document is directly linked to the current RMON2-MIB [RFC2021], andShow full document text
