                A framework for large-scale measurements
                    draft-eardley-lmap-framework-01

Abstract

   Measuring broadband service on a large scale requires standardisation
   of the logical architecture and a description of the key protocols
   that coordinate interactions between the components.  The document
   presents an overall framework for large-scale measurements and
   discusses which elements could be standardised in the IETF.  It is
   intended to assist the discussions about the potential creation of
   the LMAP working group.

Internet-Draft               LMAP Framework                February 2013

1.  Introduction

   [use-cases] discusses several use cases have been proposed for large-
   scale measurements:

   o  Operators: to help plan their network and identify faults

   o  End Users: to run diagnostic checks, such as a network speed test

   o  Regulators: to benchmark several network operators

   The LMAP framework should be useful for all these.

   The key requirement is for large scale.  A measurement system might
   have at least ~100k Measurement Agents.

   There are existing measurement systems.  However, they typically lack
   some of the desirable features for a large-scale measurement system:

   o  Standardised - in terms of the tests that they perform, the
