       IPv6 Performance and Diagnostic Metrics Destination Option
               draft-elkins-6man-ipv6-pdm-dest-option-05

Abstract

   To diagnose performance and connectivity problems, metrics on real
   (non-synthetic) transmission are critical for timely end-to-end
   problem resolution. Such diagnostics may be real-time or after the
   fact, but must not impact an operational production network. The base
   metrics are: packet sequence number and packet timestamp.  Metrics
   derived from these will be described separately. This document solves
   these problems with a new destination option, the Performance and
   Diagnostic Metrics destination option (PDM).
