Description of Working Group:

Steve Waldbusser is TA for SNMP/MIB related matters
  Matt Zekauskas is TA for Transport Retaled matters

The RMON MIB Working Group is chartered to define a set of managed
objects for remote monitoring of networks. These objects will be the
minimum necessary to provide the ability to monitor multiple network
layers of traffic in remote networks; providing fault, configuration,
and performance management, and will be consistent with the SNMP
framework and existing SNMP standards.

The following list of features for this RMON has been previously
discussed in relation to existing RMON functionality and is included
to focus these RMON activities. It is recognized that other issues
may be considered and that certain of the following issues may not
be part of the final specification(s):

  1. Application Performance Measurement

    Monitoring support for the measurement and characterization
    of network application protocols, striving to measure an
    application user's experience as closely as possible.
    The RMON-2 MIB (RFC 2021) contains a protocol directory
    that will be used to identify applications for monitoring
    purposes.

    While it is important to measure the performance of computing
    and network resources, these measurements don't give an insight
    to the actual service delivered to end-users. This end-user
    experience is best measured by the response-time and availability
    of application transactions because users interact directly
    with applications. This working group will create extensions
    to the RMON-2 MIB that will allow Application Performance
    Measurements to be retrieved with SNMP, no matter which
    technology is used to perform the measurements.

    The goal of the working group is to provide a common framework
    and set of MIB objects, within the current RMON framework,
    for the identification and characterization of application
    responsiveness and availability, and the reporting of
    test results produced by such mechanisms.  Common metrics and
    derived metrics will be characterized and reported in a manner
    consistent with the IP Performance Metrics Framework (RFC 2330).

    It is an explicit non-goal of the working group to select
    one or more mechanisms as the preferred or standard RMON
    application performance measurement mechanism. However, it is
    possible that one or more standard mechanisms will be
    developed in the future, after significant implementation
    experience has been gained by the working group.

  2. Differentiated Services Statistics Collection

    Monitoring support for Differentiated Services (DS) statistics
    collection, for the purpose of DS codepoint usage analysis
    and possibly other statistics related to DS deployment and
    performance tuning.

  3. Interface TopN Reporting

    It is often too slow or difficult to determine the
    busiest ports in devices such as high port-density switches,
    using existing RMON mechanisms.
    New monitoring support is needed for quickly determining
    the most congested (highest utilized) physical ports and
    links in an RMON-capable device with multiple interfaces.

  4. TR-RMON MIB Advancement

    The Token Ring RMON MIB (RFC 1513) is ready for standards
    track advancement. An interoperability and deployment survey
    has already been completed, but the MIB must be updated in
    SMIv2 format before it can be advanced on the standards track.


  5. Transport Performance Measurement

    There is a need for standardized means to collect and report
    selectable performance metrics and statistics derived from
    the monitoring of network packets and transport protocol states.
    The monitoring covers both passive and active traffic generation
    sources. Monitoring support for the these measurements can
    provide a drill-down capability to provide insight into the
    performance of the lower-level transactions which comprise the
    overall performance of a network application.

    The goal of the working group is to provide a common framework
    and set of MIB objects, within the current RMON framework,
    for the identification and characterization of transaction-level
    performance, and the reporting of test results produced by such
    mechanisms. Common metrics and derived statistics will be
    characterized and reported in a manner consistent with the
    IP Performance Metrics Framework (RFC 2330).

  6. SMON MIB Advancement

    The SMON MIB (RFC 2613) is ready for standards
    track advancement. An interoperability and deployment survey
    will be completed, and submitted to the IESG.
    It is possible that minor enhancements and corrections to
    RFC 2613 will be made, based on the survey findings and
    working group input.

  7. RMON-2 MIB Advancement

    The RMON-2 MIB (RFC 2021) is ready for standards
    track advancement. An interoperability and deployment survey
    will be completed, and submitted to the IESG.
    It is possible that minor enhancements and corrections to
    RFC 2021 will be made, based on the survey findings and
    working group input.

  8. RMON PI Reference Advancement

    The RMON Protocol Identifiers Reference (RFC 2895) is ready
    for standards track advancement. An interoperability and
    deployment survey will be completed, and submitted to the
    IESG. It is possible that minor enhancements and corrections
    to RFC 2895 will be made, based on the survey findings and
    working group input.

  9. Synthetic Sources for Performance Monitoring

    Mechanisms are needed for the remote control of synthetic
    packet sources and destinations, for the purpose of
    enhancing remote performance monitoring capabilities within
    IP networks and services. These mechanisms must utilize
    the RMON protocol directory for protocol encapsulation
    identification. Any interactions with the
    RMON Framework or dependencies on specific RMON MIB objects
    (if any) will be specified as well.

  10. RMON Framework

    Documentation is needed which clarifies the remote network
    monitoring framework, and describes the inter-relationships and
    dependencies between the various RMON MIB modules. A conceptual
    model is needed to help administrators and developers better
    understand data sources, the protocol directory, and the existing
    RMON statistical collections. Undocumented 'RMON folklore', as
    well as the limitations and appropriate application of various
    implementation techniques will also be addressed.

  11. Real-time Application QoS Monitoring MIB

    There is a need to extend the RMON framework to monitor end
    devices such as IP Phones, pagers, Instant Message Clients, Cell Phones,
    and PDA devices. An end-to-end user experience of the quality of
    service (QoS) and performance for such an application is a
    combination of device performance and transport network
    performance. Monitoring should be performed at the application
    layer that reflects a specific end user experience on a
    particular IP end point, reflecting specific transport network performance

There is a need to extend the RMON framework to monitor end devices
such as IP Phones, pagers, Instant Message Clients, Cell Phones,
and PDA devices. An end-to-end user experience of the quality of
service (QoS) and performance for such an application is a combination
of device performance and transport network performance. Monitoring
should be performed at the application layer that reflects a specific
end user experience on a particular IP end point, reflecting specific
transport network performance.

This working group will extend the RMON Framework to allow Real-time
Application QoS information of these types of end devices to be
retrieved with SNMP, independent of the technology used to
perform the measurements.

The WG will define a common framework and set of MIB objects,
within the current RMON framework, for the identification and
characterization of application QoS parameters, and the reporting
of the on-going measurement reports produced by these mechanisms.
Common metrics and derived metrics will be characterized and reported
in a manner consistent with the IP Performance Metrics Framework
(RFC 2330).

The WG will also define a set of RAQMON Application level QoS PDUs
to have common formats of reporting statistics between a RAQMON
Data Source and a RAQMON Report Collector. These Common
RAQMON PDUs will be transported over existing protocols, such as
RTCP or SNMP.

The measurement methodology is out of the scope of the RAQMON work
and will be in conformance with the IPPM WG recommendations, and
also may take into account considerations from application-specific
(IM and telephony) WGs as needed. This WG will consider the
cases for transport of RAQMON PDUs, including how RTCP might be
used and still meet security/privacy goals.

Security aspects related to RAQMON reports will be cognizant of
privacy and anonymity issues while being responsive to the needs
of measurement applications.
