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.

This document is a product of the IP Performance Measurement Working Group of the IETF.

This is now a Proposed Standard.

STANDARDS TRACK: This document specifies an Internet Standards Track
protocol for the Internet community, and requests discussion and suggestions
for improvements.  Please refer to the current edition of the Official
Internet Protocol Standards (https://www.rfc-editor.org/standards) for the 
standardization state and status of this protocol.  Distribution of this 
memo is unlimited.
