Technical Summary This document describes terminology for the benchmarking of devices that implement traffic control based on IP precedence or Diffserv code point criteria. The terminology is to be applied to measurements made on the data plane to evaluate IP traffic control mechanisms. New terminology is needed because most existing measurements assume the absence of congestion and only a single per-hop- behavior. This document introduces several new terms that will allow measurements to be taken during periods of congestion. Another key difference from existing terminology is the definition of measurements as observed on egress as well as ingress of a device/system under test. Again, the existence of congestion requires the addition of egress measurements as well as those taken on ingress; without observing traffic leaving a device/system it is not possible to say whether traffic-control mechanisms effectively dealt with congestion. The principal measurements introduced in this document are vectors for rate, delay, and jitter, all of which can be observed with or without congestion of the DUT/SUT. Working Group Summary This document is a product of the BMWG WG. The WG has consensus to publish this document as an Informational RFC.
