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> <dromasca@xxxxxxxxx> Ronald Bonica <rbonica@xxxxxxxxxxx>
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
