 Alternate Marking method for passive and hybrid performance monitoring
                      draft-ietf-ippm-alt-mark-13

Abstract

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

Requirements Language

   The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
   "SHOULD", "SHOULD NOT", "RECOMMENDED", "NOT RECOMMENDED", "MAY", and
   "OPTIONAL" in this document are to be interpreted as described in BCP
   14 [RFC2119] [RFC8174] when, and only when, they appear in all
   capitals, as shown here.
