3.  Scope, Goals, and Applicability

   The scope of this document is to define a protocol to measure the
   Maximum IP-Layer Capacity Metric according to the Method of
   Measurement standardized by Section 8 of [RFC9097].  As such, this
   document adheres to the applicability scope defined in Section 2 of
   [RFC9097].

   Some aspects of this protocol and end-host configuration can lead to
   support of additional forms of measurement, such as application
   emulation enabled by creative use of the load rate adjustment
   algorithm.  Per [RFC9097], that algorithm must not be used as a
   general Congestion Control Algorithm (CCA).  Instead, the load rate
   adjustment algorithm's goal is to help determine the Maximum IP-Layer
   Capacity in the context of an infrequent, diagnostic, short-term
   measurement.

   The goal is to harmonize the specified IP-Layer Capacity Metric and
   Method across the industry, and this protocol supports the
   specifications of IETF (see [RFC9097]) and other Standards
   Development Organizations (SDOs) (see, e.g., [TR-471]).

   The primary application of UDPSTP described here is the same as in
   Section 2 of [RFC7497] where:

   |  The access portion of the network is the focus of this problem
   |  statement.  The user typically subscribes to a service with
   |  bidirectional access partly described by rates in bits per second.

   UDPSTP is a client-based protocol.  It may be applied by consumers to
   measure their own access bandwidth.  Consumers may prefer an
   independent third-party domain hosting the measurement server for
   this purpose.  UDPSTP may be deployed in Large-scale Measurement of
   Broadband Performance (LMAP) environments (see [RFC7497]) and other
   independent third-party domain measurement server deployments.  A
   network operator may support operation and maintenance by UDPSTP, a
   typical intra-domain deployment.  All these deployments require or
   benefit from trusting the results, which are ensured by authenticated
   communication.
