Abstract

   Using the base loss metric defined in RFC 2680, this document defines
   two derived metrics "loss distance" and "loss period", and the
   associated statistics that together capture loss patterns experienced
   by packet streams on the Internet.  The Internet exhibits certain
   specific types of behavior (e.g., bursty packet loss) that can affect
   the performance seen by the users as well as the operators.  The loss
   pattern or loss distribution is a key parameter that determines the
   performance observed by the users for certain real-time applications
   such as packet voice and video.  For the same loss rate, two
   different loss distributions could potentially produce widely
   different perceptions of performance.
