The IETF has developed a one-way packet loss metric that measures the
loss rate on a Poisson and Periodic probe streams between two hosts.
However, the impact of packet loss on applications is, in general,
sensitive not just to the average loss rate but also to the way in
which packet losses are distributed in loss episodes (i.e., maximal
sets of consecutively lost probe packets).  This document defines
one-way packet loss episode metrics, specifically, the frequency and
average duration of loss episodes and a probing methodology under
which the loss episode metrics are to be measured.  [STANDARDS-TRACK]
