Aaron - This is to forward the draft draft-irtf-tmrg-metrics-09.txt to the IRTF, to be considered for Informational. The draft is available at "http://www.icir.org/tmrg/draft-irtf-tmrg-metrics-09.txt", and will be submitted to the internet-drafts editor at the end of this IETF. The report on the document is appended below. If this needs anything more, let me know. Many thanks, - Sally http://www.icir.org/floyd/ --------------------------------------------------------- Document shepherd: Sally Floyd Has the document had adequate review? Yes, the document has had strong reviews, from both TMRG and ICCRG members and others. The draft has had contributions or reviews from the following: Armando Caro, Dah Ming Chiu, Dado Colussi, Wesley Eddy, Nelson Fonseca, Janardhan Iyengar, Doug Leith, Saverio Mascolo, Sean Moore, David Ros, Injong Rhee, David Ros, Andras Veres, and Damon Wischik, Feedback from the ICCRG has come from Mark Allman, Lachlan Andrew, and Michael Welzl. Does the Document Shepherd have concerns that the document needs more review from a particular or broader perspective? Nope. It is a pretty low-key document. Does the Document Shepherd have any specific concerns or issues with this document that the IRTF should be aware of? There isn't any particular consensus in the IETF or research communities about the metrics that congestion control should be designed to optimize. The document makes this explicit. From the abstract: This document is a product of the Transport Modeling Research Group (TRMG), 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. How solid is the RG consensus behind this document? It is a very low-activity RG, but none of the feedback, which is from a wide range of people, has expressed unresolved problems with the document. The paragraph above from the abstract tries to make clear the nature of the consensus. Has the Document Shepherd personally verified that the document satisfies all ID nits? Yep. ---------------------------------------------------------
