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.

1 Introduction

The Real-Time Flow Measurement (RTFM) Working Group (WG) has developed a system for measuring and reporting information about traffic flows in the Internet. This document explores the definition of extensions to the flow measurements as currently defined in [RTFM-ARC]. The new attributes described in this document will be useful for monitoring network performance...
