Abstract Abstract
This document defines a reference path for Large-scale Measurement of This document defines a reference path for Large-scale Measurement of
Broadband Access Performance (LMAP) and measurement points for Broadband Access Performance (LMAP) and measurement points for
commonly used performance metrics. Other similar measurement commonly used performance metrics. Other similar measurement
projects may also be able to use the extensions described here for projects may also be able to use the extensions described here for
measurement point location. The purpose is to create an efficient measurement point location. The purpose is to create an efficient
way to describe the location of the measurement point(s) used to way to describe the location of the measurement point(s) used to
conduct a particular measurement. conduct a particular measurement.
