    IPv6 Performance and Diagnostic Metrics (PDM) Destination Option
                   draft-ietf-ippm-6man-pdm-option-10

Abstract

   To assess performance problems,  this document describes optional
   headers embedded in each packet that provide sequence numbers and
   timing information as a basis for measurements.  Such measurements
   may be interpreted in real-time or after the fact. An implementation
   of the existing IPv6 Destination Options extension header, the
   Performance and Diagnostic Metrics (PDM) Destination Options
   extension header as well as the field limits, calculations, and usage
   of the PDM in measurement are included in this document.
