Al, thanks for your work. At least the two of us read each others documents. I think it is good to work out general principles and carefully go to details later on. Your draft contains a bit of both. The really bad thing is, that as soon we go to a detailed description, we face issues. That's why I would suggest to start by the general approach. I however prefer a sufficiently defined statistical test, if our purpose is to avoid "everything" to be IPPM compliant. But may have overlooked other possibilities to reach this aim. Regards, Ruediger -----Original Message----- From: Al Morton [mailto:acmorton@att.com] Sent: Monday, July 06, 2009 9:09 PM To: Henk Uijterwaal; Geib, Rüdiger Cc: matt@internet2.edu; ippm@ietf.org Subject: Re: [ippm] Advancement of metrics to standards draft Ruediger and all, Rather that write a long e-mail on this topic (that few people will read), I wrote a short memo (that few people will read). This memo is intended as a background for discussion of some of the issues Ruediger touched-on, and several new issues that occurred to me. It is intended to help advance (not replace) either the geib or bradner versions of the metrictest memos. Whenever the advancing metrics topic comes up, I've made a taken a position at the microphone that may not have been fully understood. So, I've given-up some of my holiday weekend and included details of my rant in this short memo. I hope it will be useful to IPPM as we seek a way *up* the standards track that works. Al A New Internet-Draft is available from the on-line Internet-Drafts directories. Title : Problems and Possible Solutions for Advancing Metrics on the Standards Track Author(s) : A. Morton Filename : draft-morton-ippm-advance-metrics-00.txt Pages : 11 Date : 2009-07-06 This memo identifies some issues with the process of progressing performance metric RFCs along the standards track. This memo takes the position that the metric definitions themselves should be the primary focus, rather than the implementations of metrics. This appears to allow some simplification of the task at hand and subsequently leads to solutions for the issues raised.
