              Large-Scale Broadband Measurement Use Cases

Abstract

   Measuring broadband performance on a large scale is important for
   network diagnostics by providers and users, as well as for public
   policy.  Understanding the various scenarios and users of measuring
   broadband performance is essential to development of the Large-scale
   Measurement of Broadband Performance (LMAP) framework, information
   model, and protocol.  This document details two use cases that can
   assist in developing that framework.  The details of the measurement
   metrics themselves are beyond the scope of this document.

1.  Introduction

   This document describes two use cases for the Large-scale Measurement
   of Broadband Performance (LMAP).  The use cases contained in this
   document are (1) the Internet Service Provider Use Case and (2) the
   Regulator Use Case.  In the first, a network operator wants to
   understand the performance of the network and the quality experienced
