Abstract Abstract
The IETF has developed a one way packet loss metric that measures the The IETF has developed a one way packet loss metric that measures the
loss rate on a Poisson probe stream between two hosts. However, the loss rate on a Poisson probe stream between two hosts. However, the
impact of packet loss on applications is in general sensitive not 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 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 losses are distributed in loss episodes (i.e., maximal sets of
consecutively lost probe packets). This draft defines one-way packet consecutively lost probe packets). This draft defines one-way packet
loss episode metrics, specifically the frequency and average duration loss episode metrics, specifically the frequency and average duration
