  "abstract": "This document addresses the problem of protocol support for measuring One-Way IP Capacity metrics specified by RFC 9097. The Method of Measurement discussed in that RFC requires a feedback channel from the receiver to control the sender's transmission rate in near real-time. This document defines the UDP Speed Test Protocol (UDPSTP) for conducting measurements as described in RFC 9097 and other related measurements.",
