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.
