Abstract

   The RTFM Traffic Measurement Architecture provides a general
   framework for describing and measuring network traffic flows.  Flows
   are defined in terms of their Address Attribute values and measured
   by a 'Traffic Meter'.  This document discusses RTFM flows and the
   attributes which they can have, so as to provide a logical framework
   for extending the architecture by adding new attributes.

   Extensions described include Address Attributes such as DSCodePoint,
   SourceASN and DestASN, and Group Attributes such as short-term bit
   rates and turnaround times.  Quality of Service parameters for
   Integrated Services are also discussed.
