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.

This document is a product of the IP Performance Metrics Working Group
of the IETF.
