       IPv6 Marking and Performance and Diagnostic Metrics (MPDM)
                        draft-fear-ippm-mpdm-02

Abstract

   To assess performance problems,  this document describes optional
   headers embedded in each packet that provide marking, sequence
   numbers and timing information as a basis for measurements.  Such
   measurements may be interpreted in real-time or after the fact. This
   document specifies the IPv6 Marking and Performance and Diagnostic
   Metrics (M-PDM) Hop-byHop and Destination Options extension headers.
