A Framework for Large-Scale Measurement of Broadband Performance (LMAP)

Abstract

   Measuring broadband service on a large scale requires a description
   of the logical architecture and standardisation of the key protocols
   that coordinate interactions between the components.  This document
   presents an overall framework for large-scale measurements.  It also
   defines terminology for LMAP (Large-Scale Measurement of Broadband
   Performance).
