The IESG has approved the following document: - 'Hash and Stuffing: Overlooked Factors in Network Device Benchmarking ' <draft-ietf-bmwg-hash-stuffing-08.txt> as an Informational RFC This document is the product of the Benchmarking Methodology Working Group. The IESG contact persons are David Kessens and Dan Romascanu. A URL of this Internet-Draft is: http://www.ietf.org/internet-drafts/draft-ietf-bmwg-hash-stuffing-08.txt Technical Summary Test engineers take pains to declare all factors that affect a given measurement, including intended load, packet length, test duration, and traffic orientation. However, current benchmarking practice overlooks two factors that have a profound impact on test results. First, existing methodologies do not require the reporting of addresses or other test traffic contents, even though these fields can affect test results. Second, "stuff" bits and bytes inserted in test traffic by some link-layer technologies add significant and variable overhead, which in turn affects test results. This document describes the effects of these factors; recommends guidelines for test traffic contents; and offers formulas for determining the probability of bit- and byte-stuffing in test traffic. Working Group Summary From the initial work proposal through the final WG Last Call, there was wide agreement that this work was important for BMWG in that it added key testing considerations to our body of literature. Protocol Quality David Kessens reviewed this document for the IESG. _______________________________________________ IETF-Announce@ietf.org https://www1.ietf.org/mailman/listinfo/ietf-announce
