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.
