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.

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.
