Rate Measurement Test Protocol Problem Statement and Requirements
Abstract
This memo presents a problem statement for access rate measurement
for test protocols to measure IP Performance Metrics (IPPM). Key
rate measurement test protocol aspects include the ability to control
packet characteristics on the tested path, such as asymmetric rate
and asymmetric packet size.

1. Introduction
There are many possible rate measurement scenarios. This memo
describes one rate measurement problem and presents a rate
measurement problem statement for test protocols to measure IP
Performance Metrics (IPPM).
When selecting a form of access to the Internet, subscribers are
interested in the performance characteristics of the various
alternatives. Standardized measurements can be a basis for
comparison between these alternatives. There is an underlying need
to coordinate measurements that support such comparisons and to test
control protocols to fulfill this need. The figure below depicts
some typical measurement points of access networks.

Device -|------ Copper ------- Access Node -|-- Infrastructure -- GW
or Host \------ Radio ------- Access Node /
GW = Gateway
The access rate scenario or use case has received widespread
attention of Internet-access subscribers and seemingly all Internet-
industry players, including regulators. This problem is being
approached with many different measurement methods. The eventual
protocol solutions to this problem (and the systems that utilize the
protocol) may not directly involve users, such as when tests reach
from the infrastructure to a service-specific device, such as a
residential gateway. However, no aspect of the problem precludes
users from developing a test protocol controlled via command line
