    Leslie> Performance Metrics at Other Layers (pmol)
    Leslie> ==============================================

    Leslie> Current Status: Proposed Working Group

    Leslie> WG Chairs: TBD

    Leslie> Operations and Management Area: Dan Romascanu
    Leslie> <[e-mail]> Ronald Bonica <[e-mail]>

    Leslie> Description:

    Leslie> The successful implementation and operation of IP based
    Leslie> applications often depends on some underlying performance
    Leslie> measurement infrastructure that helps service operators or
    Leslie> network managers to recognize when performance is
    Leslie> unsatisfactory and identify problems affecting service
    Leslie> quality. Standardized performance metrics add the
    Leslie> desirable features of consistent implementation,
    Leslie> interpretation, no comparison.

    Leslie> The IETF has two Working Groups dedicated to the
    Leslie> development of performance metrics however each has strict
    Leslie> limitations in their charters:

    Leslie> - The Benchmarking Methodology WG has addressed a range of
    Leslie> networking technologies and protocols in their long
    Leslie> history (such as IEEE 802.3, ATM, Frame Relay, and Routing
    Leslie> Protocols), but the charter strictly limits their
    Leslie> Performance characterizations to the laboratory
    Leslie> environment.

    Leslie> - The IP Performance Metrics WG has the mandate to develop
    Leslie> metrics applicable to the performance of Internet data
    Leslie> delivery, but it is specifically prohibited from
    Leslie> developing metrics that characterize traffic (such as a
    Leslie> VoIP stream).

    Leslie> The IETF also has current and completed activities related
    Leslie> to the reporting of application performance metrics
    Leslie> (e.g. RAQMON and RTCP XR) and is also actively involved in
    Leslie> the development of reliable transport protocols which
    Leslie> would affect the relationship between IP performance and
    Leslie> application performance.

    Leslie> Thus there is a gap in the currently chartered coverage of
    Leslie> IETF WGs: development of performance metrics for IP-based
    Leslie> protocols and applications that operate over UDP, TCP,
    Leslie> SCTP, DCCP, Forward Error Correction (FEC) and other
    Leslie> robust transport protocols, and that can be used to
    Leslie> characterize traffic on live networks.

    Leslie> The working group will focus on the completion of two
    Leslie> RFCs:

    Leslie> 1. A PMOL framework and guidelines memo that will describe
    Leslie> the necessary elements of performance metrics of protocols
    Leslie> and applications transported over IETF-specified protocols
    Leslie> (such as the formal definition, purpose, and units of
    Leslie> measure) and the various types of metrics that
    Leslie> characterize traffic on live networks (such as metrics
    Leslie> derived from other metrics, possibly on lower layers). The
    Leslie> framework will also address the need to specify the
    Leslie> intended audience and the motivation for the performance
    Leslie> metrics. There will also be guidelines for a performance
    Leslie> metric development process that includes entry criteria
    Leslie> for new proposals (how a proposal might be evaluated for
    Leslie> possible endorsement by a protocol development working
    Leslie> group), and how an successful proposal will be developed
    Leslie> by PMOL WG in cooperation with a protocol development WG.

    Leslie> 2. A proof-of-concept RFC defining performance metrics for
    Leslie> SIP, based on draft-malas-performance-metrics. This memo
    Leslie> would serve as an example of the framework and the PMOL
    Leslie> development process in the IETF.

    Leslie> Discussion of new work proposals is strongly discouraged
    Leslie> under the initial charter of the PMOL WG, except to advise
    Leslie> a protocol development WG when they are evaluating a new
    Leslie> work proposal for related performance metrics.

    Leslie> The PMOL WG will also be guided by a document describing
    Leslie> how memos defining performance metrics are intended to
    Leslie> advance along the IETF Standards track
    Leslie> (draft-bradner-metricstest).

    Leslie> PMOL WG will take advantage of expertise and seek to avoid
    Leslie> overlap with other standards development organizations,
    Leslie> such as ETSI STQ, ITU-T SG 12, ATIS IIF, ATIS PRQC, and
    Leslie> others.

    Leslie> Milestones

    Leslie> June 08 SIP Performance Metrics Draft to IESG Review for
    Leslie> consideration as Proposed Standard

    Leslie> Sept 08 PMOL Framework and Guidelines Draft to IESG Review
    Leslie> for consideration as BCP
