The IPPM WG has developed a set of standard metrics that can be applied to the quality, performance, and reliability of Internet data delivery services. These metrics are designed such that they can be performed by network operators, end users, or independent testing groups. It is important that the metrics not represent a value judgment (i.e. define "good" and "bad"), but rather provide unbiased quantitative measures of performance. Functions peripheral to Internet data delivery services, such as NOC/NIC services, are beyond the scope of this working group. The IPPM WG has produced documents that define specific metrics and procedures for accurately measuring and documenting these metrics. This is the current list of fundamental metrics and the existing set of derived metrics. - connectivity - one-way delay and loss - round-trip delay. - delay variation - loss patterns - packet reordering - bulk transport capacity - link bandwidth capacity - packet duplication The working group will advance these metrics along the standards track within the IETF. The WG will document the process of moving documents along the standards track, based on draft-bradner-metricstest. As this process is likely to be needed by other groups as well (in particular BMWG, PMOL), the group will collaborate with other groups in order to ensure that there is consensus amongst all groups expected to use the process. Additionally, the WG will produce Proposed Standard AS documents, comparable to applicability statements in RFC 2026, that will focus on procedures for measuring the individual metrics and how these metrics characterize features that are important to different service classes, such as bulk transport, periodic streams, packet bursts or multimedia streams. Each AS document will discuss the performance characteristics that are pertinent to a specified service class; clearly identify the set of metrics that aid in the description of those characteristics; specify the methodologies required to collect said metrics; and lastly, present the requirements for the common, unambiguous reporting of testing results. The AS documents can also discuss the use of the metrics to verify performance expectations, such as SLA's, report results to specific user groups or investigate network problems. The focus is, again, to define how this should be done, not to define a value judgment. The WG may define additional statistics for its metrics if needed. Specific topics of these AS documents must be approved by the Area Directors as charter additions. The WG will work on documents describing how to compose and decompose the results of its metrics over time or space. The WG has produced protocols to enable communication among test equipment that implements the one- and two-way metrics (OWAMP and TWAMP respectively). OWAMP and TWAMP will be advanced along the standards track. Further development of these protocols will also be done inside the WG. The metrics developed by the WG were developed inside an active measurement context, that is, the devices used to measure the metrics produce their own traffic. However, most metrics can be used inside a passive context as well. No work is planned is this area though, this may be changed with AD approval. The intent of the WG is to cooperate with other appropriate standards bodies and forums (such as ATIS IIF, ITU-T SG 12, 13 and 15, MEF) to promote consistent approaches and metrics. Within the IETF process, IPPM metrics definitions will be subject to as rigorous a scrutiny for usefulness, clarity, and accuracy as other protocol standards. The IPPM WG will interact with other areas of IETF activity whose scope intersect with the requirement of these specific metrics. The WG will, on request, provide input to other IETF WG on the use of these metrics.
