              Metrics and Methods for One-way IP Capacity
               draft-ietf-ippm-capacity-metric-method-04

Abstract

   This memo revisits the problem of Network Capacity metrics first
   examined in RFC 5136.  The memo specifies a more practical Maximum
   IP-layer Capacity metric definition catering for measurement
   purposes, and outlines the corresponding methods of measurement.
