The IESG has no problem with the publication of 'Metrics for the Evaluation of Congestion Control Mechanisms' <draft-irtf-tmrg-metrics-11.txt> as an Informational RFC. The IESG would also like the RFC-Editor to review the comments in the datatracker (https://datatracker.ietf.org/public/pidtracker.cgi?command=view_id&dTag=13610&rfc_flag=0) related to this document and determine whether or not they merit incorporation into the document. Comments may exist in both the ballot and the comment log. The IESG contact person is Lars Eggert. A URL of this Internet-Draft is: http://www.ietf.org/internet-drafts/draft-irtf-tmrg-metrics-11.txt The process for such documents is described at http://www.rfc-editor.org/indsubs.html. Thank you, The IESG Secretary Technical Summary This document discusses the metrics to be considered in an evaluation of new or modified congestion control mechanisms for the Internet. These include metrics for the evaluation of new transport protocols, of proposed modifications to TCP, of application-level congestion control, and of Active Queue Management (AQM) mechanisms in the router. Working Group Summary This document is a product of the Transport Modeling Research Group (TMRG), and has received detailed feedback from many members of the Research Group (RG). As the document tries to make clear, there is not necessarily a consensus within the research community (or the IETF community, the vendor community, the operations community, or any other community) about the metrics that congestion control mechanisms should be designed to optimize, in terms of tradeoffs between throughput and delay, fairness between competing flows, and the like. However, we believe that there is a clear consensus that congestion control mechanisms should be evaluated in terms of tradeoffs between a range of metrics, rather than in terms of optimizing for a single metric. Protocol Quality Lars Eggert (lars.eggert@nokia.com) has reviewed this document for the IESG. It is planned that these metrics play a role in the evaluation of new congestion control schemes in the IRTF's ICCRG research group and related IETF working groups, such as TCPM. RFC Editor Note Section 2.2.1., paragraph 2: > bandwith-delay product changes are expected to become s/bandwith-delay/bandwidth-delay/ IESG Note Based on the Working Group Summary, the IESG believes that the second variant suggested in Appendix A of draft-irtf-rfcs-0 is appropriate for this document: "This document in not an IETF Internet Standard. It represents the individual opinion(s) of one or more members of the TMRG Research Group of the Internet Research Task Force. It may be considered for standardization by the IETF or adoption as a IRTF Research Group consensus document in the future." _______________________________________________ IETF-Announce@ietf.org https://www.ietf.org/mailman/listinfo/ietf-announce
