        A framework for large-scale measurement platforms (LMAP)
                      draft-ietf-lmap-framework-03

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.  The document
   presents an overall framework for large-scale measurements.  It also
   defines terminology for LMAP (large-scale measurement platforms).
