 Alternate-Marking Method for Passive and Hybrid Performance Monitoring

Abstract

   This document describes a method to perform packet loss, delay, and
   jitter measurements on live traffic.  This method is based on an
   Alternate-Marking (coloring) technique.  A report is provided in
   order to explain an example and show the method applicability.  This
   technology can be applied in various situations, as detailed in this
   document, and could be considered Passive or Hybrid depending on the
   application.
